This Siemens 3VA1116-4EF36-0BH0 is a 3-pole IEC frame 160 molded case circuit breaker from the 3VA1 series, rated at In=160A with a TM240 thermal-magnetic trip unit. The 'breaking capacity class S' means it can interrupt 36 kA at 415 VAC — enough for most industrial distribution boards downstream of a transformer, but not for a main service entrance with a higher fault current. The TM240 trip gives you an adjustable overload range from 112 A to 160 A via a dial, and the short-circuit pickup (Ii) is adjustable from 5× to 10× In, so you can set it to ride through motor inrush or tighten it for feeder protection. The part arrives with an undervoltage release (UVR) coil rated for 24 V DC — that's the 'UVR 24V DC' in the order code. It also includes two HQ auxiliary switches and one HQ trip alarm switch, so the panel PLC gets a separate status contact for 'breaker on' and 'breaker tripped on fault' — no need to add a separate auxiliary block later.
The UVR coil draws its 24 V DC from the control circuit; if you're reusing an existing panel's 24 V bus, verify the coil's inrush doesn't drop the bus below the PLC's hold-up threshold. The two HQ auxiliary switches and the trip alarm switch are wired via the front-accessible terminal blocks, so you can land the control wiring without pulling the breaker out of the panel.
