Product details

The 200 A rating holds flat from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C, which is the maximum operating ambient.

This breaker carries a 220 kA interrupting rating at 240 VAC, 154 kA at 415 VAC, 36 kA at 440 VAC, and 17 kA at 690 VAC. The steep drop between 415 V and 440 V reflects the transition from the IEC 60898-1 test voltage to the higher 440 V level where arc extinction becomes harder. For a 400 V distribution board (the most common industrial voltage in Europe and Asia), the 154 kA figure gives substantial headroom above typical transformer-fed fault currents of 25–50 kA. At 690 V, the 17 kA rating still covers most low-voltage motor control centre (MCC) applications. The 220 kA at 240 V is relevant for North American 120/208 V or 277/480 V systems where the line-to-neutral fault can be extreme near a large step-down transformer.

It is a fixed-mount (non-withdrawable) MCCB designed for screw-mounting onto a backplate or mounting plate inside a distribution panel. No auxiliary contacts or shunt trip are included as-delivered, but the design accepts the 3VA9688-0BL33 auxiliary trip block if remote tripping is needed.

Frequently asked questions

Where can I buy 3VA1220-6EF42-0KA0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm current availability and pricing at the time of your order.

What is the breaking capacity of 3VA1220-6EF42-0KA0 at 415 V?

At 415 VAC the interrupting rating is 154 kA, which provides substantial margin above typical industrial fault levels.

What is the rated continuous current of this MCCB?

The rated continuous current Iu is 200 A, and it holds at that value from 40 °C through 50 °C ambient before derating.

What type of overcurrent release does this breaker have?

It is fitted with a TM240 thermal-magnetic release — the thermal element handles overloads, the magnetic element handles short-circuits, and the 240 designation indicates the magnetic trip threshold.
