PRODUCT DESCRIPTION
SCHNEIDER ELECTRIC LVS04263 - Molded Case Circuit Breaker (MCCB)
This device is a 4-pole, 250A Compact NSXm series molded case circuit breaker, engineered for low-voltage industrial and commercial power distribution systems. It integrates an electronic Micrologic 4.2 trip unit, providing LSI (Long-time, Short-time, Instantaneous) overcurrent protection and short-circuit interruption with a 36kA breaking capacity at 400/415VAC. Designed for critical circuit protection, it ensures operational continuity and equipment safety in applications such as motor control centers, distribution panels, and machinery feeders.
