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.","metaTitle":"Siemens 3VA1116-4EF36-0BH0 160A Molded Case Circuit Breaker,","metaDescription":"Siemens 3VA1116-4EF36-0BH0 IEC frame 160 MCCB, 36kA breaking capacity at 415V, 160A TM240 thermal-magnetic trip, UVR 24V DC, auxiliary switches.

Submit an RFQ through the storefront; the order is sourced and quoted to order through independent distribution channels."},{"question":"What does the 36 kA breaking capacity at 415 V mean for my panel?","answer":"The 36 kA Icu at 415 V AC means this breaker can safely interrupt a fault current up to 36,000 amps without welding its contacts or rupturing the case. That's class S (standard) breaking capacity — suitable for sub-distribution boards where the prospective fault current is below that level. For main service entrances with higher fault currents, you'd step up to a class H or L frame."},{"question":"What is the adjustable trip range on this MCCB?","answer":"The TM240 thermal-magnetic trip unit allows overload protection (Ir) adjustable from 112 A to 160 A, and short-circuit protection (Ii) adjustable from 5× to 10× In — meaning 800 A to 1600 A. This lets you tune the breaker to the actual load current and motor inrush characteristics."},{"question":"What accessories are included with this order code?","answer":"This variant ships with an undervoltage release (UVR) rated 24 V DC, two HQ auxiliary switches, and one HQ trip alarm switch — all factory-fitted.
