The ComPacT NS1250N circuit breaker (C125N320FM) is part of the new ComPacT NS630bN to NS3200 range. It maintains the same reliable performance while introducing updates like a transparent front cover for better visibility of auxiliary components, an ergonomic toggle, and an optional LED trip status indicator. You can also add a wireless auxiliary contact (OF/SD) that uses the ZigBee communication protocol.

This 3-pole circuit breaker is compact and designed to save space while delivering excellent breaking capacity. It operates manually and is suitable for both general and specific applications. It has a breaking capacity (Icu) of 50kA rms at 415VAC (50/60Hz) and supports an operational voltage of up to 690VAC (50/60Hz). The breaker can be controlled with ON, OFF, or "push to trip" buttons.

Equipped with a MicroLogic 2.0 electronic control unit rated at 1250A, it offers adjustable long-time and instant protection (ANSI codes 49/50). Various optional features and accessories are available to customize the product.

Its dimensions are 327mm (height), 210mm (width), and 147mm (depth). It complies with IEC 60947-1 and IEC 60947-2 international standards. As part of Schneider Electric’s EcoStruxure Power architecture, this new generation is designed with sustainability in mind, featuring eco-friendly packaging and partnerships.
