Product details

Interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — that's serious fault-current headroom for a main or feeder breaker in a 480 V industrial panel. At 690 V it still clears 11.9 kA.

Four poles let it switch three-phase plus neutral, with the N-conductor protection set at 50% of the phase rating.

Trip unit and adjustability

The TM240 thermal-magnetic release has an adjustable magnetic trip (li) up to 1250 A, so you can dial the instantaneous pickup to coordinate downstream. Maximum power loss is 28.1 W, worth factoring into your enclosure thermal budget.

Frequently asked questions

Where can I buy 3VA1112-4FF46-0AA0?

This part is sourced to order against an RFQ through independent distribution channels; availability and price are confirmed at quote time.

Will 3VA1112-4FF46-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0?

Both are 4-pole SENTRON MCCBs in the same 3VA11 frame size, so the mounting footprint and bus-bar centers match. The difference is the trip unit: this one carries a TM240 thermal-magnetic release, while the 5EE32 variant uses an electronic trip. If the panel wiring and bus work are already sized for the same frame, it's a mechanical fit, but verify the trip coordination and accessory compatibility before swapping.

What is the interrupting capacity at 240 V?

It clears 121 kA at 240 V, which is a high-fault rating suitable for main-breaker duty in most industrial panels.
