It is built on the 160 A frame and intended for isolation and switching of loads where overload or short-circuit protection is handled upstream or by a separate device. The 500 V DC rating allows use in some DC bus or battery circuits. The trip indicator is absent, so the handle position is the only visual state cue. For applications requiring a remote status signal, an external auxiliary switch block (optional motor drive slot available) must be added. The front terminal connection accepts lug-type conductors, which is the standard for panel feeder circuits. The device measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 125 A disconnect. The front-terminal lug connection allows straightforward bus-bar or cable landing.","metaTitle":"Siemens 3VA1112-1AA36-0HA0 SENTRON Switch Disconnector, 125A","metaDescription":"Siemens 3VA1112-1AA36-0HA0 SENTRON switch disconnector, 125A rated current, 3-pole, shunt trip release, IEC frame 160.

The 3VA1110-5EE32-0JA0 is a molded case circuit breaker rated at 100 A with a TM220 thermal-magnetic release for overload and short-circuit protection. They share the same physical footprint (130×76.2×70 mm) and frame size, so the switch disconnector can drop into a panel designed for the breaker without rewiring, but it will not provide circuit protection."},{"question":"What compliance documentation is available for 3VA1112-1AA36-0HA0?","answer":"As a Siemens SENTRON product, it carries CE marking for the European market and is designed to IEC 60947-3 standards for switch-disconnectors.
