The Siemens SENTRON 3VA1180-6EF32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated 80 A at 40 °C, with a shunt trip release (STL) for remote tripping. Its 220 kA breaking capacity at 240 V means it can safely interrupt very high fault currents on a 240 V line without upstream cascading — a key spec for high-available-fault-current panels. The 800 V rated insulation voltage gives headroom for 480 V and 600 V class systems.
Compared to the 3VA1110-5ED32-0AA0 (a 100 A frame with electronic release), this 3VA1180-6EF32-0JA0 uses a TM240 thermal-magnetic release and tops out at 80 A continuous. The 3VA1110 frame is physically larger; this unit's 76.2 mm width and 70 mm depth are tighter, so a panel laid out for the 1110 frame won't accept a drop-in swap without re-drilling the mounting holes or re-terminating the bus bars.
Mounts on a DIN rail or panel-mount via the SENTRON 3VA accessory base. The shunt trip (STL) release occupies the auxiliary slot — verify the control voltage matches your trip circuit before wiring. Operating temperature range of -25 °C to 70 °C covers most indoor panel environments; storage range of -40 °C to 80 °C handles warehouse extremes. Power loss at full load is 19.2 W — factor that into enclosure thermal calculations if the panel is densely packed.
