Specs

Brand: EATON (MOELLER) Model: NZM7-150S-NA Part No.: 1003700 Product series: NZM7 Product category: Molded case circuit breaker Pole: 3P Rated current: 150A Trip unit: Thermal-magnetic Certification: UL489, CSA, IEC60947-2 Version suffix: NA (North America version) Mounting: Fixed base mounting Optional accessories: Auxiliary contact, alarm contact, shunt trip, UVR

Principle

EATON MOELLER NZM7-150S-NA 1003700 continuously monitors three-phase load current. When overcurrent persists, the thermal bimetallic element deforms and triggers delayed overload trip. When severe short-circuit fault occurs, the magnetic trip unit acts instantly and opens the main contacts. Auxiliary and alarm contacts change state synchronously to transmit fault alarm signal to PLC and SCADA. EATON MOELLER NZM7-150S-NA 1003700 isolates fault circuit to protect downstream cables, motors and loads.

Applications

EATON MOELLER NZM7-150S-NA 1003700 is widely used in industrial low-voltage distribution systems. It is commonly installed in MCC motor control centers, pump and fan feeders, factory distribution panels, packaging and chemical process cabinets. It is used for branch feeder protection, motor circuit protection and spare replacement for old Moeller NZM series control cabinets.
