Product details

The Siemens SENTRON 3VA1112-5ED32-0AG0 is a 3-pole molded case circuit breaker rated 125 A at 40 °C, with a TM210 thermal-magnetic overcurrent release designed for line protection. Its interrupting capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 75.6 kA at 440 V — enough headroom to clear high-fault conditions without cascading upstream. Current rating holds flat at 125 A from 40 °C through 50 °C, then derates gradually to 114 A at 70 °C.

The breaker measures 70 mm deep by 76.2 mm wide by 130 mm tall — a standard 3-pole MCCB footprint that drops into a SENTRON distribution panel or standalone enclosure without re-drilling the mounting plate.

Frequently asked questions

Where can I buy 3VA1112-5ED32-0AG0 and get a price?

We source this part to order against an RFQ. Submit a request with quantity and target delivery date; availability and current pricing are confirmed at quote time.

What interrupting capacity does 3VA1112-5ED32-0AG0 offer at 240 V?

It delivers 187 kA at 240 V, with 121 kA at 415 V and 75.6 kA at 440 V — suitable for high-fault industrial distribution panels.

What is the continuous current rating of 3VA1112-5ED32-0AG0 at elevated ambient temperatures?

Rated 125 A from 40 °C through 50 °C, derating to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C.

Will 3VA1112-5ED32-0AG0 drop into a panel specified around 3VA1110-5ED36-0AC0?

Both are 3-pole SENTRON MCCBs with the same 70 mm depth, 76.2 mm width, and 130 mm height, so the footprint is identical. The key difference is the overcurrent release: this unit uses a TM210 (125 A), while the 3VA1110-5ED36-0AC0 uses a different release rating. Verify the load current and coordination study before swapping.
