It's sized for the SIRIUS 3RV frame sizes S00, S0, S2, and S3, so one part covers a range of breaker footprints in the panel. The control supply is AC only — no DC variant here. At 18.5 mm wide, it tucks into a single module slot alongside the breaker. The front carries IP20 finger-safe touch protection per IEC 60529, so it's safe for open-panel work with vertical access. ## Integration notes The shunt release mounts directly onto the left side of the 3RV circuit breaker. No auxiliary contacts are included on this variant — zero NO, NC, or changeover contacts (instantaneous or leading). If you need auxiliary signaling from the shunt, you'll add a separate auxiliary switch block. Depth is 68 mm, height 90 mm, width 18.5 mm. The 18.5 mm width matches the standard DIN rail pitch.","metaTitle":"Siemens 3RV1902-1DS0 SIRIUS Shunt Release, 500 V AC","metaDescription":"Siemens SIRIUS 3RV1902-1DS0 shunt release, 500 V AC 50/60 Hz for circuit breakers S00-S3.
