FAQs
Installers should align the NZMB2-AF60-NA with the NZM2 frame, ensure the front screw terminals are securely tightened, and use the appropriate rocker lever or motor drive accessories if required. Verify alignment with the panel busbars, re-tighten all connections, and test the thermal-magnetic trip function with manufacturer-recommended procedures to confirm correct operation.
Key specs include a 60 A amperage rating, 440 Vac operating voltage, three-pole construction, NZMB2 circuit breaker type, NZM2 frame compatibility, 25 kAIC interrupt capacity, and a T185 trip type. It supports front screw connections and offers an adjustable short-circuit release range of 380-630 A delayed, with a setting range of 60-60 A.
Yes. The 60 A rating, three-pole design, and 25 kAIC interrupt capacity make it appropriate for distribution panels in automation environments. Its front-accessibility and available accessories (rocker lever, motor drive) help integrate with motor-control centers and drive systems while maintaining selective coordination in mixed-load panels.
Certification details are provided by Eaton; the model lists ‘Compliances: Contact Manufacturer.’ For regional verification, request CE marking, IP ratings, and SIL documentation from Eaton, and confirm compatibility with local electrical codes and standards before deployment.
The device offers reliable protection with a one-year warranty (or 18 months from shipment). Regular inspection of connections, trip settings, and mechanical operation helps prevent unexpected trips. The upfront robustness of a 25 kAIC breaker reduces fault-related downtime and component wear, improving total cost of ownership over time.
