Adjustable thermal protection with a fixed magnetic trip provides selective protection that minimizes nuisance tripping while ensuring rapid response to high fault currents. This translates to reduced unplanned downtime and safer equipment coordination in panels and MCCs. The 175 A rating paired with a voltage envelope of 690 Vac / 750 Vdc optimizes for high-current loads in demanding environments, allowing you to consolidate feeders and simplify maintenance. The NZM2 frame and three-pole design deliver a compact footprint with front-frame clamp terminals that simplify installation and enable safer, faster servicing in crowded panel spaces. Accessories such as rocker lever and motor drive options support easier operation and integration into motor control schemes, reducing commissioning time. Short-circuit rating of 150 kAIC and interrupt rating of 85-150 kAIC provide a healthy protection margin for fault conditions. This combination supports reliable coordination and lower lifecycle costs in industrial power systems.

FAQs
Yes. The unit uses front frame clamp terminals on the NZM2 frame and is a three-pole MCCB suitable for distribution panels and motor control centers. Ensure the enclosure width and panel space accommodate the 5.86 in width and the 5.51 in depth; confirm 690 Vac rating for your system. This configuration supports straightforward installation and serviceability.
Core performance specs include a 175 A amperage rating, voltage rating of 690 Vac / 750 Vdc, short-circuit breaking capacity of 150 kAIC, and an interrupt rating of 85-150 kAIC. The trip type is adjustable thermal with a fixed magnetic element, and it is a three-pole device within the NZMH2 family designed for reliable distribution protection.
Ideal for distribution circuits, motor feeders, and control panels in manufacturing and process environments. The NZM2 frame’s compact three-pole design, combined with front-frame mounting, makes it well-suited for space-constrained panels and high-demand equipment requiring robust fault protection up to 150 kAIC.
Certification details vary by market. Expect regionally relevant listings such as CE and UL when procuring a product like this from Eaton; always consult the official Eaton datasheet or contact Eaton for region-specific approvals and certifications before procurement.
The adjustable thermal trip and fixed magnetic trip provide reliable protection with minimized nuisance tripping, reducing downtime. Front-frame access supports quick inspections and servicing, while compatible accessories like rocker lever and motor drive options streamline operation. The combination can lower lifecycle costs through faster commissioning and easier maintenance in a distributed-panel environment.
