Product details

Thermal derating and panel fit

The 3VA1112-3EF32-0HA0: The 125 A rating holds flat through 50 °C, then derates to 120 A at 55 °C and 112.5 A at 70 °C — useful if the breaker lives near other heat sources in a dense panel. Footprint is 130 mm high, 76.2 mm wide, 70 mm deep, so it fits standard 3-pole MCCB cutouts. IP40 on the front means it's protected against tools and wires >1 mm; no sealing against water ingress, so keep it inside the enclosure.

Shunt trip and auxiliary options

This variant ships without auxiliary contacts or undervoltage release, but it does include a shunt trip (STL) release — part number 3VA9688-0BL30 for the integrated auxiliary trip. That lets you remotely trip the breaker from a PLC or E-stop circuit without adding an external contactor. The shunt trip is voltage-triggered, so wire it through a dry contact or safety relay.

Frequently asked questions

Where can I buy 3VA1112-3EF32-0HA0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity at 415 V?

At 415 V the breaking capacity is 52.5 kA. At 240 V it's 75.6 kA, at 440 V it's 32 kA, and at 690 V it's 10.5 kA.

Will 3VA1112-3EF32-0HA0 drop into a panel specified around 3VA1010-2ED32-0JA0?

No — the two breakers are different frame sizes and ratings. The 3VA1112-3EF32-0HA0 is a 125 A, 3-pole MCCB with a TM240 release, while the 3VA1010-2ED32-0JA0 is a lower-current variant. Panel cutouts and bus connections differ; verify dimensions and lug spacing before substituting.
