General Information

The PowerPacT H-, J-, and L-frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. H- and J-frame circuit breakers are available with either thermal-magnetic or MicroLogic electronic trip units. L-frame circuit breakers are available with MicroLogic electronic trip units only.

H- and J-frame circuit breakers with thermal-magnetic trip units contain individual thermal (overload) and instantaneous (short circuit) sensing elements in each pole. The amperage ratings of the thermal trip elements are calibrated at 104°F (40°C) free air ambient temperature. Per the National Electric Code® (NEC®) and the Canadian Electrical Code, standard circuit breakers may only be applied continuously at up to 80% of their rating. Circuit breakers rated for 100% operation are available but require specially-designed enclosures and 194°F (90°C) rated wire.

Devices with the MicroLogic electronic trip unit provide adjustable protection settings for greater system flexibility. In addition to electronic protection, MicroLogic trip units allow users to monitor both energy and power. Through direct access to in-depth information and networking using open protocols, PowerPacT circuit breakers with MicroLogic trip units let operators optimize the management of their electrical installations. Far more than just a circuit breaker, these devices are a measurement and communication tool ready to meet energy-efficiency needs through optimized power requirements, increased energy availability, and improved installation management.

PowerPacT™ H-, J-, and L-frame will include the industries only LED locator in an MCCB called Visi-Trip. Visi-Trip is designed to provide a visual light alert when a breaker needs to be inspected, increasing safety and saving customers time finding the concern and allowing them to being the troubleshooting process faster.

Applications

PowerPacT H-, J- and L-frame circuit breakers offer high performance and a wide range of interchangeable trip units to protect most applications.

Electronic trip units provide highly accurate protection with wide setting ranges and can integrate measurement, metering and communication functions. They can be combined with the front display module (FDM121) to provide functions similar to a power meter.

Power Meter

PowerPacT H-, J-, and L-frame circuit breakers equipped with MicroLogic 5/6 trip units offer type A (ammeter) or E (energy) metering functions as well as communication capability. Using MicroLogic trip unit sensors and intelligence, PowerPacT H-, J-, and L-frame circuit breakers provide access to measurements of all the main electrical parameters on the built-in screen, on a dedicated front display module (FDM121) or through the communication network.

Operating assistance

Integration of measurement functions provides operators with operating assistance functions including alarms tripped by user-selected measurement values, time-stamped event tables and histories, and maintenance indicators.

Front display module

The main measurements can be read on the built-in screen of MicroLogic 5/6 trip units. They can also be displayed on the equipment FDM121 along with pop-up windows signalling the main alarms.

Communication network

PowerPacT H-, J-, and L-frame circuit breakers equipped with MicroLogic 5/6 trip units provide communication capabilities. Simple RJ45 cables connect to a Modbus communication interface module.

Applications

Protection of distribution systems

The PowerPacT H-, J-, and L-frame circuit breakers provide protection against short circuits and overloads for:

  • distribution systems supplied by transformers

  • distribution systems supplied by engine generator sets

They are easily installed at all levels in distribution systems, from the main LV switchboard to the subdistribution boards and enclosures. All PowerPacT circuit breakers can protect against insulation faults by adding an external Vigirex relay.

Mission critical applications

The PowerPacT H-, J-, and L-frame mission critical circuit breakers provide high levels of selective coordination with QO and ED/EG/EJ circuit breakers.

Protection of motors

The PowerPacT H-, J-, and L-frame circuit breakers include a number of versions to protect motor applications:

  • basic short-circuit protection with electronic instantaneous only MCP or the electronic MicroLogic 1.3 M trip units, combined with a special overload relay to provide thermal protection

  • protection against overloads, short circuit and phase unbalance or loss with MicroLogic 2 M trip units

The exceptional limiting capacity of the PowerPacT circuit breakers automatically provides coordination with the motor starter.

Protection of special applications

The PowerPacT H-, J-, and L-frame circuit breakers offer a number of versions for special protection applications:

  • industrial control panels with:
    — compliance with international standards IEC 60947-2 and UL 508/CSA 22.2 N°14
    — compliance with UL 489
    — installation in universal and functional enclosures

  • 400 Hz systems

Control using automatic switches

An automatic switch version of PowerPacT H-, J-, and L-frame circuit breakers is available for circuit control. All add-on functions for the circuit breakers may be combined with the basic automatic switch function, including motor operators.

For information on other automatic switches, contact Schneider Electric.

Manual transfer systems

To ensure a continuous supply of power, some electrical installations are connected to two power systems:

  • the normal source, usually the utility (U)

  • a replacement source to supply the installation when the normal source is not available, generally from a generator (G)

A mechanical and/or electrical interlocking system between two circuit breakers or automatic switches helps minimize risk of parallel connection of the sources during switching.

A system can be manual transfer mechanical device interlocking.

Mission Critical Circuit Breakers

The PowerPacT J- and L-Frame Mission Critical circuit breakers deliver high levels of selective coordination in a flexible design that can be easily configured for a variety of applications. Tested to be selectively coordinated with the QO family of miniature circuit breakers and the ED, EG, and EJ circuit breakers, this solution provides peace of mind when power availability is critical.

An electronic trip unit provides adjustable long-time settings in three sensor sizes, allowing coverage from 70 through 600 A on 120–240, 208Y/120, 240, and 480Y/277 V systems.

Theory of Operation

There are several dynamic forces between the PowerPacT Mission Critical circuit breakers and downstream circuit breakers when a fault occurs downstream of the branch circuit breaker. Many of these events cannot be shown on the trip curve.

The PowerPacT Mission Critical circuit breakers analyze the fault current to make decisions which maximize selectivity with downstream circuit breakers. The trip units deploy a special selectivity delay to allow downstream circuit breakers to clear. However, on very high faults or if the downstream circuit breaker does not trip, the circuit breaker trips the mechanism instantaneously.

The combination of the PowerPacT Mission Critical circuit breaker and downstream circuit breakers shown in the selectivity charts in the instruction bulletin are selective due to the fact that the series impedance and the let-through from the downstream circuit breaker does not produce enough energy to trip the PowerPacT Mission Circuit circuit breaker.

This system maximizes the interaction of the circuit breakers in series to allow selectivity.

Trip Units and Trip Curves

The PowerPacT J- and L-Frame Mission Critical circuit breakers deliver high levels of selective coordination with the QO family of miniature circuit breakers and the ED, EG, and EJ circuit breakers in a flexible design that can be easily configured for a variety of applications.

Thermal-Magnetic or Electronic Trip Unit

Thermal-magnetic trip units (available on H- and J-frame circuit breakers only) protect against overcurrents and short-circuits using tried and true techniques. For applications requiring installation optimization and energy efficiency, electronic trip units offer more advanced protection functions combined with measurements.

Trip units using digital electronics are faster as well as more accurate. Wide setting ranges make installation upgrades easier. Designed with processing capabilities, MicroLogic trip units can provide measurement information and device operating assistance. With this information, users can avoid or deal more effectively with disturbances and can play a more active role in system operation. They can manage the installation, anticipate events and plan any necessary servicing.

Accurate Measurements for Complete Protection

PowerPacT H-, J-, and L-frame circuit breakers offer excellent measurement accuracy from 15 amperes on up to the short-circuit currents. This is made possible by a new generation of current transformers combining “iron-core” sensors for self-powered electronics and “air core” sensors (Rogowski coils) for measurements. The protection functions are managed by an ASIC (Application Specific Integrated Circuit) component that is independent of the measurement functions. This independence ensures immunity to conducted and radiated disturbances and increases reliability.

Numerous Security Functions

Torque-limiting screws

The screws secure the trip unit to the circuit breaker. When the correct tightening torque is reached, the screw heads break off. Optimum tightening avoids any risk of temperature rise. A torque wrench is no longer required.

Easy and sure changing of trip units

All trip units are interchangeable, without wiring. A mechanical mismatch-protection system minimizes the possibility of mounting a trip unit on a circuit breaker with a lower rating.*

“Ready” LED for a continuous self-test

The LED on the front of the electronic trip units indicates the result of the self-test running continuously on the measurement system and the tripping release. As long as the green LED is flashing, the links between the CTs, the processing electronics and the tripping mechanism are operational. The circuit breaker is ready to protect. A minimum current of 15 to 50 A, depending on the device, is required for this indication function.

A patented dual adjustment system for protection functions

Available on MicroLogic 5/6 trip units, the system consists of:

  • an adjustment using rotary switches sets the maximum value

  • an adjustment using the keypad or made remotely fine-tunes the setting. This setting may not exceed the first one. It can be read directly on the MicroLogic trip unit screen, to within one ampere and a fraction of a second.
