It operates at 690 V AC or 500 V DC, with an 800 V rated insulation voltage. Front terminal connections keep wiring accessible in a panel. The 3VA1 frame measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Mechanical service life is rated at 15,000 operating cycles typical — adequate for frequent switching in distribution or machine disconnect applications. The shunt trip release allows remote emergency-off or interlock tripping without an undervoltage release.","metaTitle":"Siemens 3VA1112-1AA36-0HH0 SENTRON Switch Disconnector, 125A","metaDescription":"Siemens SENTRON 3VA1112-1AA36-0HH0 switch disconnector in MCCB design. 125 A continuous rating, 3-pole, 690 V AC / 500 V DC.
