What it is and what it does
The Siemens 3RV1902-1DS00-0FH0 is a shunt trip accessory for SIRIUS 3RV circuit breakers in frame sizes S00 through S3. It provides remote tripping capability by energizing the shunt coil with a control signal, allowing an operator or a safety circuit to open the breaker from a distance. Rated for 500V AC at 50Hz with 100% ED (continuous duty), meaning the coil can be held energized indefinitely without overheating — no duty-cycle derating needed for applications that require the shunt trip to remain powered for extended periods.
Deployment context
Mounts directly onto the 3RV breaker's accessory slot — no separate DIN-rail footprint, no additional wiring channel. The trip coil connects to a control voltage source; when voltage is applied, the plunger mechanically trips the breaker mechanism.
