Product details

Rated continuous current and breaking capacity

That figure holds across 40 °C to 50 °C ambient; above that, the thermal-magnetic trip (TM240) derates linearly to 583 A at 70 °C, per the datasheet curve. The breaking capacity reaches 121 kA at 240 V, 76 kA at 415 V and 440 V, 53 kA at 500 V, and 10.5 kA at 690 V — so the SCCR headroom at 480 V systems is substantial, and the part is suited for high-fault utility feeds or transformer secondaries.

The breaker measures 248 mm high, 184 mm wide, and 110 mm deep.

Thermal management and power loss

Maximum power loss is 192.9 W at rated current. That figure drives ventilation requirements inside the enclosure — at full load the breaker dissipates nearly 200 W, so the panel thermal calculation must account for this to avoid exceeding the 70 °C maximum operating temperature.

Frequently asked questions

What is the breaking capacity of 3VA1463-4EF42-0AB0 at 415 V?

76 kA at 415 V, and the same at 440 V. At 500 V it drops to 53 kA, and at 690 V to 10.5 kA.

Where can I buy 3VA1463-4EF42-0AB0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the rated continuous current of this MCCB?

630 A, with derating above 50 °C: 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C.
