Product details

Line protection MCCB with ETU340 trip unit

Breaking capacity is 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that cover most industrial service-entrance and feeder applications without needing a current-limiting upstream device. The 500 A rating holds from 40 °C through 50 °C; above that, derate linearly to 410 A at 70 °C.

If you need remote signaling or shunt-trip capability, the 3VA2 accessory platform accepts those add-ons without changing the base breaker.

Frequently asked questions

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

330 kA at 415 V AC, which covers most industrial main-breaker applications without requiring a current-limiting upstream device.

Where can I buy 3VA2450-8HK32-0AA0?

This part is sourced to order against an RFQ through independent industrial distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

What does the ETU340 trip unit do?

The ETU340 is an electronic overcurrent release that provides adjustable overload (L) and short-circuit (S, I) protection curves, enabling selective coordination with downstream breakers in a distribution system.

Does this breaker include a ground-fault module?

No — this variant ships without ground-fault monitoring. If ground-fault protection is required, a separate GF module from the 3VA2 accessory range can be added.
