Eaton NZMH1-A50 NZM1 MCCB - 690V AC 150 kAIC
Part Number: NZMH1-A50
Quick Summary
NZMH1-A50 is a complete molded case circuit breaker designed for distribution protection in industrial electrical panels. It delivers reliable thermal-magnetic trip protection to prevent unplanned downtime in automation, packaging, and manufacturing lines. Many panel builders struggle with nuisance trips and maintenance access in crowded enclosures; this unit provides predictable protection, fast trip response, and a compact footprint to simplify installation. Compliances are listed as 'Contact Manufacturer' in these specs; verify CE marking, UL/CSA or IP ratings with Eaton for your region. The combination of a front-frame clamp, rockered operation, and a three-pole NZMH1 on an NZM1 frame supports easier wiring, safer servicing, and lower lifecycle costs in distributed power architectures.
