It provides remote tripping capability by energizing the coil to mechanically open the breaker — essential for emergency-stop circuits or automated shutdown sequences where the breaker sits inside a panel and needs a control signal to trip. The coil accepts AC control voltage from 20 V to 70 V at 50/60 Hz, with a nominal pickup at 24 V. For DC control, the same 20...70 V range applies. Duty-cycle rating is split: 5-second energization (short-time) across the full voltage range, and 100% continuous duty limited to 20...24 V AC. That means if you need the shunt release held energized indefinitely — say, in a safety chain that stays tripped until manually reset — keep the control voltage at 24 V AC or below. Snap-on mounting onto the breaker side face, no tools required. The screw terminals accept the control wiring directly. Front IP20 finger-safe protection per IEC 60529 means accidental contact with live terminals is prevented when the panel door is open — standard for control-gear compartments. Width is 18.5 mm — one standard modular pitch on a DIN rail. Depth 68 mm, height 90 mm. When mounted on a S00 or S0 breaker, the assembly stays within the breaker's own envelope; no extra clearance needed beyond what the breaker already requires. Check the 68 mm depth against your enclosure depth if the breaker is mounted near the backplane.","metaTitle":"Siemens 3RV6902-1DB0 SIRIUS Shunt Release, AC 24 V, 50/60 Hz","metaDescription":"Siemens SIRIUS shunt release 3RV6902-1DB0 for motor circuit breakers sizes S00/S0.
