ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC LVS04924 - Molded Case Circuit Breaker
The SCHNEIDER ELECTRIC LVS04924 is a 4-pole, 250A ComPact NSXm series Molded Case Circuit Breaker (MCCB) engineered for robust electrical distribution protection. It integrates a Micrologic 4.2 electronic trip unit, providing comprehensive overcurrent and short-circuit protection, alongside an embedded Vigi module for residual current (earth leakage) fault detection. This device is designed for critical industrial and commercial applications requiring precise circuit isolation and advanced fault discrimination in low voltage networks.
