It's designed specifically for the 3RV2 family of motor circuit breakers in frame sizes S00, S0, S2, and S3. The ring cable lug connection keeps wiring clean inside the panel. Snap-on mounting onto a DIN rail. Width is 18.5 mm, depth 68 mm, height 90 mm. Front is finger-safe against vertical contact. Protection class is IP00, for enclosed panel installation.","metaTitle":"Siemens 3RV2902-4AV0 SIRIUS undervoltage release, 400 V AC/5","metaDescription":"Siemens SIRIUS 3RV2902-4AV0 undervoltage release for 3RV2 motor circuit breakers.
