Siemens SIRIUS undervoltage release, 200 V, order code 3RV1902-1AN6, phased-out product with successor SIRIUS 3RV2.
| Parameter | Value |
|---|---|
| Series | SIRIUS |
| Product designation | undervoltage release |
It's designed for 200 V control circuits and mounts directly onto SIRIUS 3RV motor-protective circuit breakers in the S00 frame size.
Screw-type terminals accept 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) finely stranded with ferrule. Torque to 0.8…1.2 N·m. The release shares the breaker's auxiliary contact slot — verify free-wheel diode polarity if the control circuit includes an inductive load.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The SIRIUS 3RV1011-0GA10 is a motor-protective circuit breaker in the same S00 frame size with similar mounting and terminal specs, but it is a circuit breaker, not an undervoltage release — it does not perform the same undervoltage trip function. The direct functional replacement is the SIRIUS 3RV2 series undervoltage release.
