What the ratings mean for fit
The 3VA1180-6EF32-0BC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 80 A continuous current (Iu) at 40 °C, with a TM240 thermal-magnetic overcurrent release. The 220 kA breaking capacity at 240 V is the headline number for high-fault panels — it safely interrupts faults up to that level without cascading upstream, which matters when the transformer or bus is stiff. At 415 V the rating drops to 154 kA, and at 690 V to 17 kA, so the actual SCCR you can claim depends on the line voltage. This is a line-protection version — no ground-fault monitoring, no communication module, no phase-failure detection. It carries an undervoltage release (UVR) as the auxiliary trip, plus two auxiliary switches (HQ type) for status feedback to a PLC or indication lamp. The TM240 release is a fixed thermal-magnetic design — no interchangeable trip units. That means the 80 A rating is baked in; if the load grows, you replace the breaker, not the trip. For a BOM freeze or a panel that's already built, this is a one-time decision.
Deployment context
The breaker measures 76.2 mm wide by 130 mm high by 70 mm deep — standard 3-pole MCCB footprint for a 160 A frame. It mounts on a DIN rail or directly to a backplate via the integrated lugs. The IP40 front protection means it's fine inside a closed panel but not for washdown areas. Rated continuous current holds at 80 A from 40 °C up to 50 °C, then derates to 72 A at 70 °C. If the panel ambient runs hot — say near a drive cabinet or in a steel-mill control room — check the thermal curve at the actual enclosure temperature.
Panel fit vs. a common sibling
A buyer comparing this 80 A unit to the 3VA1112-5EF32-0CA0 (a 125 A frame in the same 3VA family) should know the physical footprint is different — the 125 A frame is wider and taller, so it won't drop into a panel drilled for the 80 A without rework. The 3VA1180-6EF32-0BC0 uses the 160 A frame size; the 3VA1112 uses the 250 A frame. If the panel is already punched for the smaller frame, this is the correct fit.
