Product details

The TM110M thermal-magnetic overcurrent release gives it a fixed thermal curve paired with a magnetic trip, so you get motor-matched overload protection without an external relay. Breaking capacity runs 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker can interrupt very high fault currents at typical low-voltage distribution levels. At 500 V and 690 V it still holds 7.5 kA, which covers most industrial motor branch circuits on 480/600 V class systems.

Panel fit and thermal derating

Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a compact 3-pole MCCB footprint that drops into standard SENTRON panel-mounting cutouts. Max power loss is 0.39 W, negligible for enclosure heat budgeting.

Frequently asked questions

Will 3VA1181-6MG36-0AA0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?

Yes — both are 3VA1 frame size, same 130 mm height, 76.2 mm width, 70 mm depth. The mounting cutout and busbar pattern are identical. The difference is the release: TM110M thermal-magnetic on this one vs electronic ETU on the 3VA1110.
