Schneider Electric LV431630 Molded Case Circuit Breaker

The Schneider Electric LV431630 molded case circuit breaker is a 3-pole, NSX250F frame MCCB from the Compact NSX series, rated for 250 A at 40°C and up to 690 VAC. It uses a thermal-magnetic (TM-D) trip unit to provide overload protection and magnetic short-circuit protection, with a breaking capacity of 36 kA at 380/415 VAC and an impulse withstand of 8 kV. Rated insulation voltage is 800 V and it operates on 50/60 Hz networks. This fixed-mount device is widely used in industrial power distribution, including control panels, switchboards, motor control centers, HVAC systems, and pump control systems, for reliable circuit protection and quick isolation. Durability specs include up to 20,000 mechanical cycles and up to 10,000 electrical cycles, and it complies with IEC 60947-2. Common replacements include Schneider Electric LV432630, LV433630, and LV429630.
