Out if stock but available for backorder.

Schneider Electric LV431950 is a Moulded Case Circuit Breaker (MCCB) with embedded earth leakage protection, part of the NSX250F Vigi sub-range. It features a lug connection type and is designed with 4 poles. This MCCB offers thermal protection for overload scenarios, magnetic protection against short-circuits, and earth leakage protection with Vigi functionality. It has a rated current of 250A and a rated insulation voltage of 800V. The protection settings are adjustable, with over-current settings ranging from 0.7 to 1.0 times the rated current (In), short-circuit pickup current adjustable between 5-10 times In, and a fully protected neutral pickup current set at 1 times the rated current (Ir). The rated impulse voltage stands at 8kV, and the residual current sensitivity is adjustable between 30mA to 10A. The trip current rating is 250 AT, and the frame current rating is 250 AF. It boasts a mechanical durability of 20,000 operations at no load and an electrical durability of 20,000 operations at 440Vac with half the rated current (In/2), and 10,000 operations at 440Vac with the rated current (In). The rated voltage for phase-to-phase connections is 690V, with all 4 poles protected. The trip unit type is a TMD Interchangeable Thermal-Magnetic, adjustable for precise protection needs. The time delay for tripping is adjustable between 0 to 800 milliseconds, offering flexibility in response times. It falls under utilisation category A.
