It's the component that lets a remote signal — from an emergency-stop button, a safety relay, or a PLC output — trip the breaker electrically, without a person needing to be at the panel. Rated for 110–127 V AC (50/60 Hz) or DC, it pulls a maximum apparent power of 40 VA and a maximum active power of 40 W at DC. The shunt trip measures 31.2 mm deep, 25.7 mm wide, and 65.1 mm high. It snaps into the accessory slots on the left side of a 3VM breaker — three slots are available, so this occupies one of them alongside other accessories like an undervoltage release or auxiliary switch. The stripped length for the wiring is 10 mm (0.4 in), which is standard for the spring-cage terminals on these modules. This is a panel-mount accessory that integrates directly onto the breaker body. No extra DIN rail space is consumed — the footprint is the breaker's own. For a panel OEM or wireman, the key constraint is that the shunt trip must be wired with the correct polarity for DC operation (the coil is polarized), and the control voltage must be stable within the 110–127 V range to guarantee dropout below the minimum hold voltage.","metaTitle":"Siemens 3VM9908-0BL32 SENTRON Shunt Trip, 110-127V AC/DC","metaDescription":"Siemens 3VM9908-0BL32 SENTRON shunt trip accessory for 3VM breakers to 630A. 110-127V AC/DC, 40VA, 4kV surge.
