Product details

MCCB for high-fault line protection

Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and still delivers 17 kA at 690 V — meaning it can clear high-energy faults upstream without cascading to downstream gear. Thermal derating is minimal up to 50 °C (still 250 A), then drops to 243 A at 55 °C and 223 A at 70 °C. The 57 W maximum power loss is the heat you need to vent — factor it into the enclosure sizing calculation.

Auxiliaries and releases

The shunt trip allows remote tripping from an E-stop or safety relay — common for emergency-off circuits.

Footprint is 140 mm wide × 158 mm tall × 70 mm deep. The 70 mm depth keeps it within typical 200 mm deep enclosure clearance.

Frequently asked questions

Where can I buy 3VA1225-6GF42-0KH0 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures published here.

What is the interrupting capacity of 3VA1225-6GF42-0KH0 at different voltages?

220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V (–). The 690 V rating is the one to check for 600 V class systems.

What auxiliaries come fitted on this MCCB?

2 auxiliary switches plus 1 trip alarm switch (HQ type) and a shunt trip release (STL) are factory-installed. No undervoltage release or ground-fault monitoring on this variant.
