B-Line Eaton Series NZM complete , NZM2-, NZMN2, Thermal-magnetic trip type, Three-pole, 160A, 690 Vac, 750 Vdc, 50 kAIC, Distribution circuit protec

The part is NZMN2-A160-NA, an Eaton NZM series molded case circuit breaker on the NZM2 frame. It is a three-pole, 160A thermal-magnetic device rated 690 Vac and 750 Vdc with a 50 kAIC interrupting rating. Order by that full designation, since the NZM2 frame covers a range of amperages and breaking capacities.

Yes. The NZMN2-A160-NA carries a dual rating of 690 Vac and 750 Vdc, so it can be applied on three-phase distribution up to 690 volts AC and on DC systems up to 750 volts. That DC capability is why NZM frames show up in solar, battery and traction panels as well as standard AC distribution boards.

This one is thermal-magnetic, which means a bimetal element handles overload and a magnetic element handles short circuit. That is the standard pick for distribution circuit protection, which is the class this breaker is built for: feeders, sub-panels and general load circuits where you do not need adjustable long-time, short-time or ground-fault settings. If you need selective coordination with downstream devices or field-adjustable curves, an electronic trip unit version of the NZM frame is the better fit.

Plan for a device measuring 8.5 x 4.5 x 4.5 inches and weighing 5.4 lb. Check that footprint against your available panel bay and door cutout before you commit, and account for the motor drive if you are ordering it, since motorized operators add depth on the front of the breaker.

Yes. The NZMN2-A160-NA is a complete breaker configured with a rocker lever and motor drive, so it can be opened, closed and reset electrically rather than only by hand at the panel. That is what makes it usable in remote switching, automatic transfer and load management schemes where nobody is standing at the door.

It will. With a 690 Vac rating and three poles, the NZMN2-A160-NA covers 208V, 240V, 480V and 600V three-phase distribution, and 160A is the frame's continuous rating. Size the conductors and the load to that 160A, and confirm the fault current at that point is within the breaker's 50 kAIC capacity.

It ships as a complete molded case circuit breaker, thermal-magnetic trip included, with the rocker lever and motor drive accessories as configured. You are not assembling a frame and a separate trip unit the way you would with some electronic-trip product lines.
