Product details

Interrupting capacity is the headline: 75.6 kA at 240 VAC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The TM210 release is a thermal-magnetic trip unit.

Panel fit and environment

Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for DIN-rail or direct-mount panel integration. The 76.2 mm width (3 inches) matches typical SENTRON 3VA base frame spacing, so retrofitting into an existing 3VA panel layout should not require busbar rework.

Frequently asked questions

Will 3VA1050-3ED32-0AE0 drop into a panel specified around 3VA1110-5ED36-0AC0?

Both are 3-pole SENTRON 3VA MCCBs on the same base frame, so the 76.2 mm width and 70 mm depth are identical — no busbar or mounting rework needed. The difference is rating: this one is 50 A with a TM210 release, while the 3VA1110 variant carries a higher current and different trip curve.
