FAQs
Install the NZMH2-AF175-NA using the front screw terminals on the three-pole NZM2 frame. Ensure proper clearance and mounting in a compatible panel, then wire L1, L2, and L3 per the 690 Vac / 750 Vdc rating. Set the overload trip to the 175-175A range and verify wiring integrity with a torque check according to Eaton's datasheet.
Key specs include an amperage rating of 175 A, voltage rating of 690 Vac / 750 Vdc, short-circuit breaking capacity of 150 kAIC, and an adjustable overload range with a fixed 175 A setting. The device is a three-pole NZM2 frame MCCB with front screw connection and includes optional rocker lever and motor-drive compatibility.
Yes. The three-pole NZM2 frame and adjustable overload/short-circuit protection make it suitable for motor protection in three-phase systems. When used in motor control centers, coordinate with appropriate overload relays and starters, and consider motor-in-rush characteristics to optimize protection without nuisance trips.
