Eaton NZMH2-4-A125 Molded Case Circuit Breaker - NZM2 Frame

High-capacity protection for mixed- voltage systems: The NZMH2-4-A125 offers a 125 A rating with both 690 Vac and 750 Vdc capabilities, enabling protection of main feeders and DC-powered drives within the same panel. This reduces device count, simplifies stocking, and lowers lifecycle costs by consolidating protection duties in a single, reliable breaker. It’s well suited to demanding industrial environments where multiple voltage rails coexist. Adjustable thermal and magnetic trip: The unit provides adjustable thermal and magnetic trip settings with a 100-125 A range. This enables precise coordination with load profiles, minimizing nuisance trips and improving uptime. Panel builders can tailor protection to specific motor starts, pump loads, and process shifts, while maintaining safety margins. High fault tolerance: Short-circuit breaking capacity of 150 kAIC and an interrupt rating of 85-150 kAIC yield robust clearance under fault conditions. This reduces downstream equipment damage and supports safer start-up sequences in high-energy applications such as heavy industry and large drives. Compact, panel-friendly form: NZM2 frame, four-pole construction, front screw connections, and a compact footprint (8.75 in × 5 in × 4.75 in; 3.4 lb) simplify installation in space-constrained panels. This enables quicker retrofits and easier field servicing, especially in control cabinets where space is at a premium. Ease of integration and support: Included accessories such as rocker lever and motor drive options improve operation and automation compatibility. Warranty and support include a 1-year policy from installation or 18 months from shipment, plus direct Eaton assistance for spare parts and service, reducing total cost of ownership and simplifying procurement.
