Rated for 230 V AC at 50 Hz and 240 V AC at 60 Hz, this release is a straight swap-in accessory for any 3RV2 breaker in those frame sizes. No wiring modification needed — it mounts into the breaker's accessory slot and connects to the control voltage. ## Integration Note The release snaps into the accessory slot on the left side of the 3RV2 breaker. No tools required for installation; the breaker must be in the OFF position. Control wiring is brought to the screw terminals on the release body — torque to 0.8 Nm for reliable contact. Because it shares the same accessory slot as auxiliary contacts and shunt trips, verify slot availability before specifying. Only one accessory can occupy the slot at a time.","metaTitle":"Siemens 3RV1902-1AP00-0FJ0 Undervoltage Release, 230V AC 50/","metaDescription":"Siemens 3RV1902-1AP00-0FJ0 undervoltage release for S00-S3 circuit breakers.
