Compact® NSF and NSJ 150 to 600 A Circuit Breakers

Section 7—Mounting Configurations

The plug-in configuration makes it possible to:

Extract and/or rapidly replace the circuit breaker without having to touch connections

Allow for addition of future circuits at a later date

Parts of a Plug-in Configuration

When the circuit breaker is in the connected position, the primary voltage is fed through the circuit breaker by means of multiple finger disconnects. Control voltage of internal accessories is provided through secondary disconnects.

Compact® circuit breaker (fixed mounted)

Set of power and secondary disconnects that are added to the circuit breaker

Plug-in base for mounting through a front panel or on rails

Safety trip, to be installed on the circuit breaker, which causes automatic tripping if the circuit breaker is ON before engaging or withdrawing it; the safety trip does not prevent circuit breaker operation, even when the circuit breaker is disconnected

Mandatory short terminal shields

The plug-in mounting is Listed under UL file E113555 and Certified under CSA file LR 69561.

DRAWOUT MOUNTING

The chassis is made up of two side plates installed on the base and two other plates mounted on the circuit breaker.

Chassis Functions All functions of the plug-in base, plus:

Disconnected position: the power circuits are disconnected, the circuit breaker is simply "withdrawn" and may still be operated (on, off, push-to-trip)

Circuit breaker may be locked using 1 to 3 padlocks—diameter 0.19 to 0.31 inch (5 to 8 mm)—to prevent connection

Auxiliaries can be tested using manual auxiliary connector

Mounting

On a backplate, through a front panel or on rails

 

Horizontally or vertically
