Product details

The 3VA1050-2ED42-0CA0: Breaking capacity is voltage-dependent: 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. Four poles, insulation voltage rated 800 V, and a TM210 thermal-magnetic overcurrent release.

Maximum power loss is 17.1 W. In a sealed, uncooled enclosure that heat adds up — account for it in your thermal calculation alongside the other breakers in the same row. The storage floor is the handling limit, not the running limit — don't let a cold warehouse trip you up during commissioning.

Frequently asked questions

How do I get current pricing and availability for 3VA1050-2ED42-0CA0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels.

Will 3VA1050-2ED42-0CA0 drop into a panel specified around 3VA1010-2ED32-0JA0 without rewiring?

Both are 4-pole SENTRON MCCBs with the same 70 mm depth, 101.6 mm width, and 130 mm height — so the mechanical footprint is identical. The electrical difference is the rating: this one is 50 A with a UVR; the 3VA1010 variant is a lower-current frame. If the panel was wired for a 50 A feed, it drops in. If the original was a smaller frame, check the lug size and bus bar ampacity before swapping.

What compliance documentation does this brand provide for 3VA1050-2ED42-0CA0?

As a SENTRON MCCB from Siemens, it carries the standard CE marking for the European market and is designed to meet IEC 60947-2. RoHS and REACH declarations are available from Siemens documentation. Specific UL/CSA listings should be verified against the exact variant — the order code suffix may indicate a different certification package.
