PRODUCT DESCRIPTION
SCHNEIDER ELECTRIC LV481524 - Molded Case Circuit Breaker
The SCHNEIDER ELECTRIC LV481524 is a ComPact NSXm series Molded Case Circuit Breaker (MCCB) engineered for comprehensive overcurrent and short-circuit protection in low voltage electrical distribution systems. Featuring a 4-pole configuration and an integrated Micrologic 4.1 electronic trip unit, this device provides precise LSI (Long-time, Short-time, Instantaneous) protection for critical industrial infrastructure, commercial installations, and machinery control panels. It is designed for fixed mounting applications requiring reliable circuit interruption and selective coordination.
