It mounts on the left side of the breaker and triggers a remote trip when its coil is energized — standard practice for emergency-stop circuits, undervoltage protection schemes, or interlocking between breakers in a distribution panel. Coil accepts 24 V AC at 50/60 Hz or 12–30 V DC, drawing up to 30 VA apparent power on AC or 45 W active power on DC. That 45 W DC figure is the peak inrush; steady-state hold is lower, but the control transformer or DC supply must be sized for the inrush without voltage sag. The shunt trip occupies a compact footprint — 65.1 mm tall, 25.7 mm wide, 31.2 mm deep — and clips directly onto the left side of the 3VM breaker without additional DIN-rail space. The stripped length of 10 mm (0.4 in) on the flying leads matches standard ferrule or direct-wire termination in the control cabinet. Surge voltage resistance of 4 kV.","metaTitle":"Siemens 3VM9908-0BL30 Shunt Trip, 24V AC/DC, SENTRON","metaDescription":"Siemens SENTRON 3VM9908-0BL30 shunt trip for 3VM breakers to 630A. 24V AC 50/60Hz / 12-30V DC.
