The Siemens 3RV1902-1DP00-0FJ0 is a shunt trip accessory for the 3RV2 series of circuit breakers, sized S00 through S3. It provides remote tripping capability on a 210-240V AC control supply at 50/60 Hz, with a continuous-duty (100% ED) rating. The coil also accepts an extended range of 190-330V AC for a 5-second duty cycle (CDF or ED), covering brownout or generator-sourced control power without dropping out.
What the Ratings Mean for Fit
The 210-240V AC nominal coil voltage matches standard European and North American control transformer secondaries. The 100% ED rating means the coil can be energized continuously without overheating — important for applications where the shunt trip must remain armed for extended periods, such as emergency-stop circuits or remote-disconnect panels. The extended 190-330V AC range at 5-second duty covers momentary trip commands from a wider voltage band, useful when the control supply is unregulated or shared with motor starting loads. The size S00-S3 designation means this shunt trip mounts directly onto the 3RV2 breaker family across the full frame range. No adapter plate or wiring harness change is needed when swapping between a size S00 and an S3 breaker — the accessory footprint is common. Panel integration is straightforward: the trip unit clips onto the breaker side, and the two coil leads terminate at the control terminal block.
Deployment Context
This shunt trip is used in motor control centers and distribution panels where a remote signal (E-stop, PLC output, fire-alarm relay) must open the breaker without an operator at the handle. The 3RV2 breaker itself mounts on DIN rail or directly to a backplate, so the trip unit follows the same panel layout.
