SCHNEIDER LV432409 ComPacT NSX400H Molded-Case Circuit Breaker Basic Frame

SCHNEIDER LV432409 is a 4-pole molded-case circuit breaker basic frame from Schneider ComPacT NSX series for low-voltage power distribution applications. This molded-case circuit breaker basic frame is the empty breaker body without trip unit, rated 400A continuous current and 70kA ultimate short-circuit breaking capacity at 415V AC. The molded-case circuit breaker basic frame allows flexible assembly with different electronic trip units to meet varied protection requirements. The molded-case circuit breaker basic frame supports panel fixed installation inside low-voltage switchgear cabinets.

Low-voltage power circuit mechanical switching & modular trip unit mounting is the core function of SCHNEIDER LV432409 ComPacT NSX400H Molded-Case Circuit Breaker Basic Frame. Low-voltage power circuit mechanical switching & modular trip unit mounting provides mechanical contact make-and-break function for 4-wire three-phase distribution networks including neutral conductor. Reliable Low-voltage power circuit mechanical switching & modular trip unit mounting accepts user-selected trip modules to configure overload, short-circuit and earth-fault protection functions. Configurable Low-voltage power circuit mechanical switching & modular trip unit mounting matches with auxiliary contacts, shunt trip and under-voltage release accessories for remote monitoring and control.

This unit delivers outstanding power distribution cabinet hardware mechanical & dielectric performance for indoor electrical panel environments. power distribution cabinet hardware mechanical & dielectric performance adopts high-strength flame-retardant molded housing complying with IEC 60947-2 standards. Robust power distribution cabinet hardware mechanical & dielectric performance features visible contact status indicator and built-in arc quenching chamber for safe fault current interruption. Complete power distribution cabinet hardware mechanical & dielectric performance supports quick trip unit assembly and disassembly for on-site protection scheme modification.

SCHNEIDER LV432409 operates at rated voltage up to 690V AC, 50/60Hz, 4-pole basic frame without trip unit. It is discontinued legacy Schneider hardware. Widely deployed in industrial plants, commercial buildings, water treatment facilities for low-voltage main feeder and branch circuit protection after fitted with corresponding trip units. It acts as an original critical circuit breaker frame spare part for Schneider ComPacT NSX low-voltage power distribution solutions.
