Product Positioning

The 3RV2902-1AV0 is an undervoltage release device specifically designed for Siemens SIRIUS 3RV2 series motor protection circuit breakers. It has a rated voltage of 400/440V AC and can automatically trigger the circuit breaker to trip when the power supply voltage drops abnormally, thus preventing damage to the motor due to low voltage operation.

Core Product Advantages and Features

Undervoltage protection mechanism

When the power supply voltage is detected to be lower than the set value, the circuit breaker will automatically trip to prevent the motor from being damaged due to continuous operation under abnormally low voltage.

Rated 400/440V AC

It is compatible with 50/60Hz dual-frequency power systems and meets the power specifications requirements of Taiwan and various international standards.

Installed directly on the side of the circuit breaker

It adopts a snap-on installation method on the 3RV2 S00/S0/S2 circuit breaker body, eliminating the need for additional wiring space and enabling rapid construction.
