Product FAQs
6 answersWhat equipment is the Federal Pacific NM632175 designed to fit?
This N-frame breaker is designed for bolt-on installation in legacy Federal Pacific switchgear and industrial panelboards. It is not compatible with residential Stab-Lok load centers.
Are the trip settings adjustable on the NM632175?
Yes, the thermal-magnetic trip unit features an adjustable magnetic element for instantaneous short-circuit protection, while the thermal long-time protection remains fixed.
Can the 600V-rated NM632175 be used on lower voltage systems?
Yes, this breaker is rated for up to 600VAC but can be safely applied on 240V or 480V systems. The interrupting capacity increases at lower voltages, providing up to 42kAIC at 240VAC.
Does the NM632175 include ground fault or short-time delay protection?
No. This breaker features a standard LI (Long-Time, Instantaneous) trip unit. It does not provide ground fault or short-time protection functions.
Is the Federal Pacific NM632175 still manufactured?
Federal Pacific Electric is no longer in business, making the NM632175 a legacy component. It is typically sourced to maintain existing FPE industrial switchgear rather than for new installations.
How does the NM632175 connect to the panelboard bus?
The NM632175 utilizes a bolt-on connection type. It must be physically bolted to the panelboard bus bars, which provides a secure and reliable connection for high-amperage industrial loads.
