Schneider Electric's LV426802 is an undervoltage release accessory designed for spring-operated mechanisms. This specific unit operates with a nominal coil voltage of 48V AC at 50/60Hz or 48V DC, providing essential protection against voltage fluctuations in industrial control systems. It is commonly integrated into circuit breaker assemblies to ensure safe operation by tripping the breaker when voltage drops below a critical threshold.
