NM632175 - 175Amp Circuit Breaker

NM632175 - 175Amp Circuit Breaker

The NM632175 175-amp circuit breaker is a practical choice for maintaining or replacing protection in three-phase commercial and industrial electrical systems. It uses a thermal magnetic trip mechanism to respond to both overloads and short circuits, helping keep equipment protected under normal operating conditions. The molded case design holds up well in everyday electrical rooms, and the bolt-on mounting style allows for a solid, secure fit during installation. This breaker is commonly used where dependable fault protection is required without changing the existing setup.
