Rated continuous current Iu is 100 A, with a rated insulation voltage Ui of 800 V and max operating voltage of 690 V AC at 50/60 Hz or 500 V DC. This is a pure disconnect — no overload or short-circuit protection elements inside. It's designed for manual isolation and switching of loads where the upstream protection is handled by a separate device. The integrated shunt trip (STL) release operates on 220-250 V DC or 208-277 V AC, letting you remotely trip the disconnect via a control signal. The unit also carries a voltage trigger for undervoltage or remote trip monitoring. Panel footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — the standard 3-pole MCCB cutout for the SENTRON 3VA frame 160 family. Main circuit connection is via front busbar terminals; the busbar connection type means it's meant for horizontal or vertical busbar systems in a distribution panel, not lugged cable entry. Auxiliary contacts and the shunt trip are factory-fitted — no field-kit installation needed. The unit accepts an optional motor drive for remote motorized operation if the application requires it. The 100 A continuous rating is the current it can carry indefinitely without exceeding temperature limits — sized for a 100 A feeder or load circuit. The 800 V insulation voltage means it's suitable for 400/480 V and 690 V systems with adequate clearance. The 2 kA short-time withstand at 1 s and 0.5 s is the fault current it can hold closed during coordination; it's not a breaking capacity rating since this is a disconnect, not a circuit breaker. The shunt trip coil draws its power from the control voltage — verify the control transformer or DC supply can source the inrush. The 2 HQ auxiliary switches are rated for typical control circuit loads; they share the same terminal compartment as the main busbar connection.","metaTitle":"Siemens 3VA1110-1AA32-0KC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0KC0 switch disconnector, 100 A rated continuous current, 3-pole, IEC frame 160.
