The Siemens 3VA1180-6GD42-0AA0 is a SENTRON-series molded case circuit breaker (MCCB) rated for 80 A continuous, with a 4-pole configuration and a TM210 thermal-magnetic overcurrent release. The interrupting ratings are what make this part stand out: 220 kA at 240 V AC, 154 kA at 415 V, and still 17 kA up to 690 V — meaning it handles high-fault-current scenarios like transformer secondaries or large motor control centers without cascading upstream. The 70 mm depth and 101.6 mm width fit standard panel layouts, and the IP40 front protection keeps dust out of the enclosure face.
What the ratings mean for fit
The 80 A rating holds from 40 °C up to 50 °C ambient without derating — at 55 °C it's 78 A, at 70 °C it's still 74 A. That thermal curve matters if the breaker sits in a warm enclosure near other heat sources. The TM210 release is a fixed thermal-magnetic type: thermal for overload protection, magnetic for short-circuit. No trip indicator, no undervoltage release, no communication module — this is a straight line-protection breaker, not a metering or remote-trip device. Power loss at full load is 19.2 W, which is modest for an 80 A frame; factor it into enclosure thermal calculations if you're packing multiple breakers in a small panel.
Panel fit and environment
Mounts in a standard distribution panel or motor control center — the 70 mm depth leaves room behind the door for wiring gutters. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C, so it's fine for unheated warehouses or outdoor enclosures as long as the front stays IP40-protected. Rated insulation voltage is 800 V, which covers 480 V and 600 V systems with margin.
