Product details

Line protection breaker with 187 kA interrupting capacity

The interrupting capacity reaches 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 440 VAC — figures that place it in a high-fault-current class suitable for main or large-feeder positions in industrial distribution panels.

The 125 A continuous rating holds across 40 °C to 50 °C ambient without derating; above that it steps down to 120 A at 55 °C and 112.5 A at 70 °C. Front-side IP40 protection means the breaker face is sealed against tools and solid objects over 1 mm, but not against moisture; suitable for indoor switchgear enclosures.

Frequently asked questions

How do I get current pricing and availability for 3VA1112-5EF32-0AD0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels — the part is sourced to order, not held on a speculative shelf.

Will 3VA1112-5EF32-0AD0 drop into a panel specified around 3VA1112-5EF32-0CA0 without rewiring?

The two order codes share the same frame size, pole count, and mounting footprint — the 0CA0 variant carries a different overcurrent release curve. Physically they interchange, but the trip characteristic differs; verify coordination studies before substituting.

What is the interrupting capacity of this MCCB at 415 V?

121 kA at 415 VAC, per the manufacturer's rating. At 440 V it is 75.6 kA, and at 690 V it drops to 17 kA.
