Product details

At 440 V AC the breaker still clears 75.6 kA, and at 500 V and 690 V it holds 17 kA. That spread means it can serve as a main breaker on a 480 V panel or a feeder breaker in a 690 V industrial system, though at higher voltages the available fault current must stay under 17 kA.

The 3VA1112-5ED42-0AA0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a compact 4-pole footprint that fits standard distribution panelboards. Maximum power loss is 28.1 W, which matters for thermal budgeting in a sealed enclosure.

Frequently asked questions

How do I get current pricing and availability for 3VA1112-5ED42-0AA0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

Will 3VA1112-5ED42-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0 without rewiring?

Both are 4-pole SENTRON 3VA1 MCCBs sharing the same 101.6 mm width and 70 mm depth, so the mechanical footprint is identical. The deciding difference is the overcurrent release: the 5ED42-0AA0 uses a TM210 thermal-magnetic release, while the 5EE32-0AA0 uses a different release variant. Verify the trip curve and rating match your coordination study before swapping.

What compliance documentation does this brand provide for 3VA1112-5ED42-0AA0?

As a Siemens SENTRON product, the 3VA1112-5ED42-0AA0 carries standard IEC/EN 60947-2 certification for molded case circuit breakers. Compliance documentation including RoHS and REACH declarations is available through Siemens Industry Online Support. The rated insulation voltage is 800 V.
