The Siemens SENTRON 3VA1116-1AA32-0BA0 is a 3-pole switch disconnector in a molded-case circuit breaker (MCCB) footprint, rated 160 A continuous at 40 °C through 50 °C. It provides visible isolation and safe disconnection under load — no overload or short-circuit protection built in, so it's strictly a disconnect, not a breaker. The undervoltage release (UVR) set for 24 V DC will trip the switch open if control voltage drops, which is common in emergency-stop chains or safety circuits where loss of power must open the load.
That covers most 400 V and 480 V industrial distribution systems with headroom. Maximum power loss is 38 W, which is modest for this current class and won't drive much additional heat inside a ventilated cabinet.
It's a front-terminal, busbar-connection design — the main circuit wires land on the front face, not the back. That's typical for MCCB-style disconnectors in panelboard or switchboard layouts. No auxiliary contacts are included, and there's no communication function — it's a pure disconnect with UVR. If you need aux contacts for status feedback, you'll add them externally.
