FAQs
NZMH2-A160-BT-NA is designed for the NZM2 frame and three-pole configurations, enabling straightforward mounting in standard distribution panels. Ensure mounting provisions match front frame clamp terminals and that electrical clearance, termination space, and wiring routes accommodate the 5.9 in length, 7.7 in height, and 4.1 in width. Always verify that your enclosure supports 690 Vac/750 Vdc and the device’s 160 A rating for safe installation.
Key specs include an amperage rating of 160 A, voltage rating of 690 Vac / 750 Vdc, and a trip type of adjustable thermal and magnetic. The short-circuit breaking capacity is 150 kAIC, with a setting range of 125-160 A. These figures indicate the device protects against overloads and short circuits while allowing on-site setting to match load demands, improving protection coordination and reducing the risk of unnecessary trips.
Yes. The NZMH2-A160-BT-NA is specified for 690 Vac and 750 Vdc, making it suitable for most industrial distribution panels and control circuits. Its three-pole configuration supports balanced protection across phases, and the adjustable trip enables alignment with machine and process loads, ensuring reliable protection and safe shutdown under fault conditions.
