Section 6—PowerPacT R-Frame Molded Case Circuit Breakers

PowerPacT R-Frame Performance

R-Frame Unit-Mount

R-Frame I-Line

Providing unparalleled performance and control, the R-frame circuit breakers features the exclusive MicroLogic electronic trip units, which allow for a range of sophisticated applications for metering and monitoring. In addition, trip units can be interchanged in the field to allow for maximum flexibility.

The compact size and smaller footprint of the R-frame circuit breaker permits higher density installations using I-Line panelboards and switchboards. These circuit breakers are available in 100% rated construction up to 3000 A to meet a broad range of commercial and industrial application needs.

Both standard and 100% rated construction circuit breakers are available in 3000 A with a sensor size range of 600–3000 A.
Interrupting ratings (AIR):

Voltage	G	J	K	L
240 Vac	65 kA	100 kA	65 kA	125 kA
480 Vac	35 kA	65 kA	65 kA	100 kA
600 Vac	18 kA	25 kA	65 kA	50 kA

The K interrupting rating is recommended for applications having high inrush and/or non-linear loads such as large motors, transformers, motors with soft starts, etc.
ComPacT circuit breaker size allows for smaller footprint installations using I-Line panelboards and switchboards. Fifteen-inch width provides increased density installation.
Most field-installable accessories are common to all frame sizes for easier stocking and installation
Selection of four interchangeable MicroLogic trip units available, with PowerLogic power metering and monitoring capabilities available in advanced trip units.
Compatible with PowerLogic systems and high amperage power circuit breakers.
Built-in Modbus protocol provides an open communications platform and eliminates the need to purchase additional, proprietary network solutions.
Connection options include bus, cable or I-Line for installation flexibility.

PowerPacT R-Frame Automatic Molded Case Switches

Automatic molded case switches are available in unit-mount construction from 1200–3000 A. Automatic switches are similar in construction to electronic trip circuit breakers except that long-time protection is not present. The switches open instantaneously at a non-adjustable magnetic trip point calibrated to protect only the molded case switch itself. They must be used in conjunction with a circuit breaker or fuse of equivalent rating.

NOTE: Catalog numbers for automatic switches are designated by “000” in positions 7–9 (ampere rating) and S12, S16, S20, S25, or S30 in positions 11–14 (trip system). See Catalog Number for M-, P- and R-Frame (UL/IEC Dual-Rated) Circuit Breakers.

PowerPacT R-Frame Termination Information

I-Line circuit breakers have lugs standard on the O/OFF end. Unit-mount circuit breakers and switches are equipped for direct bus connection.

For cable connections, optional terminal pad RLTB or equivalent bus structure is required. RLTB kits are included with 2500 A 100% rated circuit breakers. The RL3TB kits are included with the 3000 A, 80% and 100% rated circuit breakers. For other circuit breakers, order terminal pad kit RLTB and optional lugs separately. Refer to Section 11—PowerPacT M-, P- and R-Frame and ComPacT NS630b–NS3200 Dimensional Drawings for terminal pad kit dimensions.

All Other R-Frame Circuit Breakers	Required for Cable, Optional for Bus	8	RLTB	RLTB4

For cable connection to RLTB, use AL2500RK lug. See Mechanical, Compression, and Distribution Lugs.

PowerPacT R-Frame Continuous Current Rating

All circuit breakers marked as 100% rated can be continuously loaded to 100% of their rating. 100% rated circuit breakers are available in unit-mount construction up to 3000 A and in I-Line construction up to 1200 A.

Because of the additional heat generated when applying circuit breakers at 100% of continuous current rating, the use of specially-designed enclosures and 194°F (90°C) wire is required. The 194°F (90°C) wire must be sized according to the ampacity of the 167°F (75°C) wire column in the NEC. Minimum enclosure size and ventilation specifications are indicated on a label on the circuit breaker, in the circuit breaker instruction bulletin and in Enclosure Sizes.

Circuit breakers with 100% rating can also be used in applications requiring only 80% continuous loading.

PowerPacT R-Frame Control Wiring

Control wiring is connected to terminals located under the circuit breaker accessory cover.

		NOTE: All diagrams show circuit breaker in open position.
A–Do not remove factory-installed jumpers between Z3, Z4 and Z5 unless ZSI is connected. B–Do not remove factory-installed jumper between T1 and T2 unless neutral CT is connected. Do not install jumper between T3 and T4. C–For proper wiring of neutral CT, refer to Instruction Bulletin 48041-082-03 shipped with it. D–24 Vdc power supply for trip unit must be separate and isolated from 24 Vdc power supply for communication modules.
