It is built for isolation, not overcurrent protection: no overload release, no short-circuit release inside. The job is to safely break load current and provide a visible disconnect gap for a downstream circuit. The main circuit connects via busbar connection at the front terminals, which keeps the wiring plane clean in a panel. Rated insulation voltage is 800 V, and it handles up to 690 V AC 50/60 Hz or 600 V DC across the poles. The DC rating at 600 V makes it usable in battery or UPS circuits within that voltage ceiling. This one is wound for 24 V DC. The UVR with leading contact option is not present here — the release acts directly, no early-warning auxiliary ahead of the dropout. That means if the 24 V DC control supply fails, the disconnector opens and stays open until the coil is re-energized manually or electrically. The width is the 4-pole frame width. Front-face protection is IP40. No last-time-buy clock, no forced substitute search. The UVR at 24 V DC is a specific variant — if the panel design calls for that undervoltage release function, this order code is the direct fit. The closest functional peer in the 3VA1 family is the 3VA1112-5EF32-0CA0 — a 3-pole, 125 A molded case circuit breaker with a TM240 thermal-magnetic release, line protection version, and a 24 V DC UVR. Both share the 70 mm depth, 130 mm height, IP40 front, and the same mechanical endurance of 15 000 cycles. The critical difference: the 3VA1116-1AA42-0BA0 is a switch disconnector only — no overcurrent protection — while the 3VA1112-5EF32-0CA0 is a full MCCB with LI protection. If the panel design already has upstream overcurrent protection and only needs a load-break disconnect with UVR, the 3VA1116 is the correct part. If the circuit requires integral short-circuit and overload protection, the 3VA1112-5EF32-0CA0 is the right frame. Also the pole count: 4 vs 3 — the 3VA1116 switches the neutral; the 3VA1112 does not.","metaTitle":"Siemens 3VA1116-1AA42-0BA0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0BA0 switch disconnector, 160 A rated continuous current, 4-pole, IP40 front, with undervoltage release 24V DC.
