Product details

SENTRON 3VA1220-5EF32-0AH0 — 200 A MCCB with TM240 release

This is a straight feeder or distribution breaker, not a motor-protection device. Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

Thermal derating and ambient performance

Above that, it steps down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C.

Auxiliary switching and trip indication

The trip indicator is present. This means the breaker reports its position and trip state back to a PLC or status panel without an add-on module — useful for remote monitoring on a distribution board.

Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The 70 mm depth includes the arc-chamber housing; allow clearance for outgoing cable lugs and the handle throw.

Frequently asked questions

Will 3VA1220-5EF32-0AH0 drop into a panel specified around 5SQ2370-2YA05 without rewiring?

The 3VA1220-5EF32-0AH0 is a Siemens SENTRON MCCB; the 5SQ2370-2YA05 is a different manufacturer's breaker. Footprint and terminal spacing differ — mechanical fit and bus-bar alignment must be verified on the actual panel layout before assuming a drop-in replacement.
