Schneider Electric NS1250N ComPacT Molded‑Case Circuit Breaker

Schneider Electric NS1250N is a high‑current molded‑case circuit breaker from the ComPacT NS series for low‑voltage power distribution main‑feeder and heavy‑load branch‑circuit protection applications. This molded‑case circuit breaker features 1250 A rated continuous current with 50 kA ultimate short‑circuit breaking capacity at 415 V AC. The molded‑case circuit breaker supports both 3‑pole and 4‑pole configurations, compatible with MicroLogic series electronic trip units. The molded‑case circuit breaker accepts fixed‑mount or draw‑out chassis installation inside low‑voltage switchgear assemblies.

Low‑voltage heavy‑duty power system overcurrent & short‑circuit protection is the core function of Schneider Electric NS1250N ComPacT Molded‑Case Circuit Breaker. Low‑voltage heavy‑duty power system overcurrent & short‑circuit protection provides adjustable long‑time overload, short‑time delay and instantaneous short‑circuit tripping via MicroLogic electronic trip unit. Reliable Low‑voltage heavy‑duty power system overcurrent & short‑circuit protection delivers precise selective coordination for upstream and downstream distribution devices to limit fault‑affected zones. Configurable Low‑voltage heavy‑duty power system overcurrent & short‑circuit protection can serve as main incoming breaker, large motor feeder or generator output protection within industrial and commercial power networks.

This unit delivers outstanding high‑power distribution cabinet‑grade hardware performance for indoor electrical switch‑room environments. high‑power distribution cabinet‑grade hardware performance complies with IEC 60947‑2 international distribution safety standards. Robust high‑power distribution cabinet‑grade hardware performance supports comprehensive optional accessories including auxiliary contacts, shunt trip, under‑voltage release and electrical motor operator for remote control and status feedback. Complete high‑power distribution cabinet‑grade hardware performance features visible contact position indication and built‑in LED fault diagnostic indicators for fast on‑site inspection.

Schneider Electric NS1250N operates at rated operational voltage up to 690 V AC 50/60 Hz. Multiple MicroLogic trip unit options (2.0, 5.0E, 6.0) offer basic protection or advanced power‑measurement functions. Draw‑out version allows hot removal for maintenance without full busbar de‑energization. Widely deployed in factories, data centres, hospitals, water‑treatment plants and commercial building main power switchgear. It acts as an original critical high‑current power‑protection spare unit for Schneider ComPacT NS low‑voltage distribution solutions.
