It is designed for the IEC frame 160 platform and carries no overload or short-circuit protection — it is a pure disconnect, not a circuit breaker. Front terminal connections (clamp type) simplify bus-bar and cable landing in a panel. The 70 mm depth, 76.2 mm width, and 130 mm height fit standard DIN-rail enclosures; check your gland-plate clearance against the 70 mm projection, especially in shallow backboxes. That is unusual for a disconnect in this frame size; most parts lose 10–20 % above 50 °C. The 15 000 mechanical operating cycles typical is a service-life figure for the disconnect mechanism — not a short-circuit endurance rating (this unit has no short-circuit protection). ## Deployment context The front terminal arrangement keeps wiring accessible for panel builders. No auxiliary contacts or releases are fitted; if you need remote status or undervoltage tripping, you will add external components. The optional motor-drive extension (not included) allows remote switching.","metaTitle":"Siemens 3VA1112-1AA36-0AA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA36-0AA0 switch disconnector in MCCB design. 125 A continuous rating, 3-pole, 690 V AC, 500 V DC.

The 3VA1112-1AA36-0AA0 is a pure switch disconnector with no overload or short-circuit protection; the 5EE32 variant includes electronic overload protection. They share the same 125 A continuous rating and 3-pole form factor, so a panel designed for one can typically accept the other without rewiring, provided the protection scheme is adjusted accordingly."},{"question":"How do I get current pricing and availability for 3VA1112-1AA36-0AA0?","answer":"Submit an RFQ through this listing.
