The Siemens SIRIUS 3RV1912-1CG6 is an undervoltage release with a leading auxiliary switch, rated at 100 V. It drops the main contactor or circuit breaker when supply voltage falls below the dropout threshold, protecting motor loads from undervoltage conditions and preventing automatic restart on brownout recovery.
The leading auxiliary switch provides early status feedback to the control system before the main contacts open, useful for sequencing downstream logic or safety interlocks.
It is an undervoltage release for SIRIUS motor protection and control assemblies. It trips the main device when supply voltage drops, preventing motor damage from undervoltage conditions.
