Product details

It uses a TM240 thermal-magnetic overcurrent release, so the trip curve is fixed — no electronic adjustment on this variant. Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. The 250 A rating holds flat from 40 °C through 50 °C, then derates gradually to 223 A at 70 °C.

The integrated auxiliary trip is a separate order code 3VA9608-0BB24. If your BOM already calls that out, it matches this breaker.

Dimensions 70 mm deep, 140 mm wide, 158 mm high. No auxiliary contact version, no communication function, no phase failure detection, no ground fault monitoring on this variant — if you need those, you are looking at a different suffix.

Frequently asked questions

Where can I buy 3VA1225-5EF42-0CA0 and get a price?

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 price and delivery window.

What is the closest functional second-source for 3VA1225-5EF42-0CA0?

The closest peer within the SENTRON 3VA family is the 3VA1112-5EF32-0CA0, but it is a lower-rated frame — verify your load current and breaking capacity requirements before substituting. The 3VA1225 carries 250 A continuous and 187 kA at 240 V; the 3VA1112 frame typically tops out lower on both. Panel cut-out dimensions may differ — check the mounting footprint.

What is the depth of 3VA1225-5EF42-0CA0?

70 mm deep, 140 mm wide, 158 mm high. The 70 mm depth fits standard 200 mm deep enclosures without crowding the gland plate.

What compliance documentation does this breaker carry?

As a Siemens SENTRON MCCB, it is designed to meet IEC 60947-2 and relevant UL/CSA standards. Specific certificates (UL, CSA, CE, UKCA, EAC) are listed on the manufacturer's declaration — request the compliance pack with your RFQ.
