Product details

Its breaking capacity varies with system voltage — 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V or 690 V — so the actual fault-clearing capability depends on your supply voltage.

At 240 V the breaker interrupts up to 220 kA — that's a very high interrupting rating, typical for a main or large feeder breaker in a high-fault industrial panel. Above 500 V the rating settles at 17 kA, which still covers most downstream branch circuits. The thermal rating holds full 25 A up to 50 °C ambient (–); at 55 °C and 60 °C it derates to 24 A, and at 65–70 °C it runs at 23 A. That derating curve means you can mount it in a warm enclosure without losing much capacity.

Built-in auxiliary and release options

That means you get remote status indication (open/closed/tripped) plus a remote trip capability — useful for emergency-stop circuits or load-shedding schemes.

Frequently asked questions

What is the breaking capacity of 3VA1125-6GF46-0KF0 at different voltages?

At 240 V it interrupts 220 kA, at 415 V it is 154 kA, at 440 V it is 121 kA, and at 500 V and 690 V it is 17 kA (–). The rating drops as voltage rises, so match it to your system's available fault current.

What auxiliary switches and releases come with this breaker?

It includes one auxiliary switch plus one trip alarm switch (HQ) and a shunt trip release (STL). No undervoltage release or ground-fault monitoring is fitted.
