Product details

Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V — the steep drop at 690 V tells you this breaker is optimized for low-voltage main or feeder duty, not 690 V motor circuits. Above that, derate linearly: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C.

Auxiliary configuration and integration

The shunt trip allows remote tripping via a control signal — useful for emergency-stop or interlock circuits. Mounts in standard panel cutouts for 3-pole SENTRON 3VA2 frames.

Maximum power loss is 96 W at rated load. Factor that into panel thermal calculations if mounting multiple breakers in a sealed enclosure.

Frequently asked questions

What is the interrupting capacity of this MCCB at 240 V?

330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. The 690 V figure is low — this breaker is intended for low-voltage main or feeder duty, not 690 V motor circuits.

Where can I buy 3VA2340-7HL32-0HH0 and what is the lead time?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

Does this breaker include a shunt trip or undervoltage release?

It includes a shunt trip (STL) for remote tripping. No undervoltage release is fitted on this variant.
