Product details

Thermal derating and power loss

The 3VA1110-5GF42-0AA0: The breaker carries its full 100 A up to 50 °C ambient; above that it derates linearly to 91 A at 70 °C. Maximum power loss is 25 W — a figure to account for in enclosed panel heat budgets, especially when multiple breakers stack on a DIN rail.

Mounting and protection

Front-face protection is IP40 — suitable for dry indoor panels where tools or fingers won't contact live parts. The 4-pole design handles three-phase plus neutral in a single unit, common for main disconnects in 400 V distribution boards. No undervoltage release or ground-fault monitoring is built in; those are external add-ons if the application requires them.

Frequently asked questions

What is the interrupting capacity of 3VA1110-5GF42-0AA0 at different voltages?

At 240 V it interrupts 187 kA; at 415 V it's 121 kA; at 440 V it's 75.6 kA; at 500 V and 690 V it's 17 kA. These ratings govern selectivity coordination with downstream breakers.

Where can I buy 3VA1110-5GF42-0AA0?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit a request for a firm quote.

Will 3VA1110-5GF42-0AA0 drop into a panel specified for 3VA1110-5ED32-0AA0?

Both are 4-pole 100 A SENTRON MCCBs with the same 70 mm depth and 101.6 mm width, so the physical footprint matches. The key difference is the overcurrent release: this unit uses a TM240 thermal-magnetic release, while the 5ED32 variant uses a different release curve. Verify the trip characteristic matches your coordination study before swapping.
