It is a pure isolating device — no overload release, no short-circuit protection — meaning it functions as a load-break switch for manual disconnection under load, not as a circuit breaker. The 125 A rating suits it for feeder isolation on distribution panels, motor control centers, or as a main disconnect on smaller sub-distribution boards where upstream protection already exists. Rated operational voltage goes to 690 V AC 50/60 Hz and 500 V DC, so it covers common industrial voltages up to 480Y/277 and 400 V three-phase systems, plus DC bus applications up to 500 V. ## Shunt trip and auxiliary contact configuration That gives three independent signal paths: one for status feedback to a controller, one for a remote indicator lamp, and one for the trip alarm to flag an event. The 3VA1112-1AA32-0JH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact footprint for a 125 A disconnect. Main circuit connection is via busbar connection on front terminals, so it bolts directly onto a busbar system inside the panel, not lugged cable.","metaTitle":"Siemens 3VA1112-1AA32-0JH0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0JH0 switch disconnector, IEC frame 160, 125 A rated continuous current, 3-pole, shunt trip 110-127 V AC/DC.

The 3VA1112-1AA32-0JH0 is a switch disconnector with busbar connection and a shunt trip. The mounting hole pattern and frame size (160 A frame) are shared, but the wiring interface and functional role are different. A panel designed for the breaker would need rewiring to accept the switch disconnector."},{"question":"What compliance documentation does this brand provide for 3VA1112-1AA32-0JH0?","answer":"Siemens SENTRON 3VA series products carry IEC 60947-3 compliance for switch-disconnectors, CE marking, and UKCA certification.
