What ships in the box
The Siemens 3RV1902-1DP00-0FQ0 is a shunt trip accessory for SIRIUS 3RV circuit breakers, covering frame sizes S00, S0, S2, and S3. It operates on a 210-240V AC supply at 50/60 Hz with 100% ED (continuous duty), and also accepts 190-330V AC for a 5-second short-time duty (CDF/ED) — useful for applications where the trip coil is energized only during a fault event, not held continuously.
What the ratings mean for fit
The 210-240V AC 50/60Hz rating at 100% ED means the coil can be energized continuously without overheating — typical for a shunt trip that stays powered in a control circuit and trips on loss of voltage. The 190-330V AC 5-second duty rating covers the inrush or short-duration pulse from a remote trip signal, common in emergency-stop or undervoltage-release circuits. The size S00-S3 range ensures mechanical fit across the SIRIUS 3RV breaker family; no adapter bracket is needed for these frame sizes.
