Product details

MCCB for high-fault panel builds

At 440 V it still holds 75.6 kA, dropping to 17 kA at 500 V and 690 V. Four poles let it switch three-phase plus neutral in a single envelope, saving a DIN row over separate breakers.

The 25 A rating holds flat from 40 °C to 50 °C; above that it derates to 24 A at 55 °C and 60 °C, then 23 A at 65 °C and 70 °C. A panel OEM wiring a 24 A continuous load at 60 °C ambient needs to account for that step-down. Front IP40 protects against tool drops and dust ingress; the body is open-frame behind the panel, so clearance to live parts follows local wiring rules.

Frequently asked questions

What is the interrupting capacity of 3VA1125-5ED46-0AA0 at 415 V?

At 415 VAC the breaker is rated 121 kA. At 240 V it reaches 187 kA, at 440 V it is 75.6 kA, and at 500 V or 690 V it holds 17 kA.

Where can I buy 3VA1125-5ED46-0AA0 and get current pricing?

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

What is the thermal derating curve for 3VA1125-5ED46-0AA0?

The breaker carries 25 A from 40 °C to 50 °C, then derates to 24 A at 55 °C and 60 °C, and to 23 A at 65 °C and 70 °C. At 70 °C ambient the usable current is 23 A.

What is the overcurrent release type on 3VA1125-5ED46-0AA0?

It uses a TM210 thermal-magnetic release — a fixed thermal trip with magnetic short-circuit protection, designed for line-protection duty.
