Product details

The thermal derating curve is already mapped: at 55 °C it's still good for 78 A, at 65 °C it's 75 A, and at 70 °C it holds 74 A. At 240 V it's rated for 75.6 kA, at 415 V it's 52.5 kA, at 440 V it's 32 kA, and at 500 V or 690 V it's 11.9 kA.

Built-in auxiliaries and release options

The two auxiliary switches give you status feedback (open/closed) for the PLC or panel indication without needing an add-on module.

Panel fit and environment

Maximum power dissipation is 21.7 W — account for that heat in your enclosure thermal calculation if you're packing several breakers side by side.

Frequently asked questions

Where can I buy 3VA1180-3EF36-0DC0 and how do I get a price?

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 price and lead time.

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

At 415 V the breaking capacity is 52.5 kA. At 240 V it's 75.6 kA, at 440 V it's 32 kA, and at 500 V or 690 V it's 11.9 kA.

What is the continuous current rating at elevated ambient temperatures?

Rated 80 A at 40 °C, 45 °C, and 50 °C. It derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.

Does this breaker include an undervoltage release?

Yes, it ships with an undervoltage release (UVR) and two auxiliary switches (HQ type) already integrated.
