Eaton NZMN1-4-A100 Molded Case Circuit Breaker - UL Listed
Part Number: NZMN1-4-A100
Quick Summary
The Eaton NZMN1-4-A100 molded case circuit breaker protects distribution panels by interrupting faults in AC systems. Engineers often struggle to balance high-current protection with fast, coordinated trips across multi-pole panels. This device is UL Listed for reliable distribution protection with a four-pole NZMN1 configuration, 690 Vac, and a 50 kAIC interrupt rating. From a procurement perspective, it simplifies maintenance with standard accessories like a rocker lever and clear amperage ratings, delivering value through compliance and serviceability. Key protections include the 100 A amperage rating and the 80-100 A overload range, making it well-suited for modern industrial panels.
