Product details

At 415 V AC the interrupting rating drops to 9 kA, so verify the point-of-use SCCR before specifying this breaker in a 400 V line-up.

That means in a tightly packed panel with elevated internal temperature, the continuous current capability is still over 110 A — useful for derating headroom without upsizing the frame.

At 25.4 mm wide (1 inch), 130 mm tall, and 70 mm deep, this single-pole MCCB occupies a standard 1-module width on a DIN rail.

The SENTRON series carries UL, CSA, and IEC certifications standard for the 3VA platform. RoHS and REACH compliance documentation is available through the manufacturer's support portal.

Frequently asked questions

Where can I buy 3VA1112-5ED12-0AA0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at that time.

What is the interrupting capacity of 3VA1112-5ED12-0AA0?

121 kA at 240 V AC and 9 kA at 415 V AC — the higher figure suits service-entrance duty where fault current is high; the 415 V rating must be checked against the available fault current at the installation point.

What is the continuous current rating of 3VA1112-5ED12-0AA0?

125 A continuous at 40 °C ambient, derating to 114 A at 70 °C. The full 125 A holds through 50 °C.

What compliance documentation does Siemens provide for 3VA1112-5ED12-0AA0?

Standard SENTRON-series documentation includes UL, CSA, and IEC certifications, plus RoHS and REACH declarations available through the manufacturer's support portal.
