Eaton NZMN4-4-VE800 Molded Case Circuit Breaker - UL Listed
Part Number: NZMN4-4-VE800
Quick Summary
NZMN4-4-VE800 is a molded case circuit breaker used to protect electrical distribution panels in industrial plants. Designers often struggle to choose protective settings that deliver reliable fault clearance while minimizing nuisance trips across dynamic load profiles. This unit carries UL Listed certification, and combines an 800 A rating with a 690 V AC maximum and a 50 kAIC short-circuit rating for demanding feeders. Its four-pole NZM4 frame, front-screw terminals, and bolt-on mounting support straightforward installation in panelboards. Optional rocker lever or motor-drive accessories simplify operation and retrofit. By delivering predictable protection and scalable current settings (400–800 A), it supports compliant, cost-efficient distribution circuit protection in modern industrial environments.
