Eaton NZMH2-A160-NA Molded Case Breaker - 85-150 kAIC
Part Number: NZMH2-A160-NA
Quick Summary
The Eaton NZMH2-A160-NA molded case breaker provides reliable overcurrent protection for industrial power distribution and motor-control panels. Engineers often struggle to coordinate adjustable thermal and magnetic trips across fluctuating loads, risking nuisance trips or under-protection. This unit uses a NZM2 frame with three poles, a 160 A rating, and 690 Vac / 750 Vdc compatibility, delivering 85–150 kAIC interrupt capacity. Compliance details (such as CE/UL markings) are provided by the manufacturer; review the datasheet for exact certifications. With front screw connections and optional accessories like a rocker lever or motor drive, installation is fast and maintenance is predictable, supporting distribution protection in demanding environments. This combination translates to reduced downtime, safer operation, and more efficient spare-part planning for your facility.

Adjustable thermal and magnetic trip allows precise protection for motor loads and process equipment, reducing nuisance trips and extending equipment life. This precision translates into measurable efficiency gains on manufacturing lines and safer operation in critical processes. The NZM2 frame compatibility and front screw terminals simplify installation and future maintenance, lowering field labor costs and improving reliability in panel assemblies. The 690 Vac / 750 Vdc rating supports mixed AC/DC networks commonly found in industrial facilities, while the 960-1600 A delayed trip helps manage inrush during motor startup without compromising protection. With a short-circuit breaking capacity of 150 kAIC and an interrupt rating of 85-150 kAIC, this device provides robust fault-current protection in dense switchboards. Accessories such as rocker lever and motor drive, plus a 125-160 A setting range, offer flexible integration for diverse applications and easier retrofit. A one-year warranty (or eighteen months from shipment) reduces procurement risk while ensuring reliable service life for critical protection gear.
