ComPacT NS630b–NS1600 Performance

ComPacT NS630b–NS1600

The ComPacT NS630b–NS1600 circuit breakers feature 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 small footprint of the NS circuit breakers permit higher density installations. These circuit breakers are available in ratings up to 1600 A to meet a broad range of commercial and industrial application needs.

Circuit breakers are available in 1600 A construction with a sensor size range of 250–1600 A.

ComPacT circuit breaker size allows for smaller footprint installations. Nine 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 or cable for installation flexibility.
Additional options are available for five-cycle closing, stored energy mechanisms and drawout-mounting.

ComPacT NS630b–NS1600 Drawout Configuration

The drawout configuration makes it possible to:

extract and/or rapidly replace the circuit breaker without having to touch connectors
allow for the addition of circuits at a later date

ComPacT NS630b to NS1600 circuit breakers should be installed vertically only.

ComPacT NS630b-NS1600 Interrupting Ratings

See PowerPacT P-Frame Interrupting Ratings.

ComPacT NS630b-NS1600 Electrically-Operated Circuit Breakers

Electrically-operated NS630b–NS1600 circuit breakers are available in unit-mount construction up to 1600 A and are denoted in the catalog number by an “M_” suffix. These come equipped with a two-step stored energy mechanism and come standard with a motor assembly.

Motor assemblies provide on and off control from remote locations. The assemblies contain a spring-charging motor (MCH), a shunt trip (MX) and a shunt close (XF) and are available in standard or communicating versions. An SDE overcurrent trip switch is also included for trip indication. When remote indication of the circuit breaker status is required, use of a circuit breaker with an OF auxiliary switch (for on-off indication).

Motor Assembly Voltage Ratings (Vn)

Voltage Type	Voltage Ratings (Vn)
Vac 50/60 Hz	48, 100–130, 220–240, 380–415
Vdc	24–30, 48–60, 100–130, 200–250

For catalog numbers, see Spring-Charging Motors (MCH) for P-Frame Circuit Breakers.

ComPacT NS630b-NS1600 Termination Information

Unit-mount circuit breakers and switches have mechanical lugs standard on both ends. These lugs accept aluminum or copper wire. Manually operated circuit breakers are also available in drawout construction.

Other terminations are available as accessories for non-standard applications. See Mechanical, Compression, and Distribution Lugs for more lug options.

ComPacT NS630b-NS1600 Accessories

Accessories are available either factory-installed or field-installable. They can be installed in accessory compartments behind the circuit breaker accessory cover. See M-frame, P-frame, R-frame and NS630b–NS3200 Accessory Availability for available accessories.

ComPacT NS630b-NS1600 Control Wiring

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