Product details

The Siemens SENTRON 3VA1050-2ED32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated 50 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL) auxiliary release.

Rated breaking capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.

Maximum power loss is 14.6 W — relevant for enclosure thermal calculations when grouping multiple breakers.

Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts. The shunt trip (STL) adds a small module on the side; verify clearance if retrofitting into a tight gland plate.

Frequently asked questions

Where can I buy 3VA1050-2ED32-0KA0 and how is it quoted for volume?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the closest functional second-source — 3VA1010-2ED32-0AD0?

The 3VA1010-2ED32-0AD0 is a lower-current sibling (10 A frame) with the same TM210 release and shunt trip, so it shares the same footprint and wiring pattern. It will drop into a panel specified for the 3VA1050 without rewiring, but the continuous rating must match the load — the 50 A 3VA1050 cannot be replaced by a 10 A breaker.

What is the depth of 3VA1050-2ED32-0KA0?

The depth is 70 mm (2.76 in).

What is the width of 3VA1050-2ED32-0KA0?

The width is 76.2 mm (3 in).

Will 3VA1050-2ED32-0KA0 drop into a panel that was specified around 3VA1010-2ED32-0AD0 without rewiring?

Yes — both share the same 3-pole footprint, same TM210 release, and same shunt trip module, so the physical fit and terminal layout are identical. The only difference is the continuous current rating (50 A vs 10 A), so the upstream protection and conductor sizing must be verified.

What compliance documentation does Siemens provide for 3VA1050-2ED32-0KA0?

Siemens SENTRON MCCBs typically carry UL 489, CSA C22.2 No. 5, IEC 60947-2, CE, and RoHS/REACH declarations. Specific certs for this order code should be confirmed at quote time, as the evidence does not list them individually.
