Product details

125 A MCCB with 187 kA interrupting capacity

Max power loss runs 28.1 W, which factors into enclosure thermal rise calculations.

Fit and panel integration

Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — standard 3-pole MCCB width for a 125 A frame. The 70 mm depth is shallower than many older frames, which helps in shallow enclosures or gland-plate clearance. The basic switch assembly is order code 3VA11125EF360AA0.

At 55 °C it derates to 122 A, at 60 °C to 120 A, at 65 °C to 117 A, and at 70 °C to 114 A (–).

Frequently asked questions

What is the interrupting capacity of 3VA1112-5EF36-0JC0 at different voltages?

187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V (–).

Does 3VA1112-5EF36-0JC0 include a shunt trip?

Yes, it includes a shunt trip (STL) release and 2 HQ auxiliary switches.

How do I get current pricing and availability for 3VA1112-5EF36-0JC0?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
