Product details

Siemens 3VA2140-0HM32-0AA0 — 40 A SENTRON MCCB with ETU330 Trip Unit

The Siemens 3VA2140-0HM32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 40 A continuous current, built around the ETU330 electronic trip unit. It's designed for line protection in distribution panels, with a 440 kA breaking capacity at 415 V and 187 kA at 690 V — enough to handle high-fault utility feeds without cascading upstream breakers. That means it catches phase-to-ground faults without a separate GFCI module — a space saver on the DIN rail.

At 86 mm deep, 105 mm wide, and 181 mm tall, this MCCB fits standard SENTRON 3VA2 panel cutouts. Power loss is 1.2 W maximum at rated load, so thermal rise inside a dense panel is minimal — no special derating needed for adjacent breakers in a standard 40 °C ambient.

Frequently asked questions

What is the breaking capacity of this MCCB at 415 V and 690 V?

It's rated for 440 kA at 415 V and 187 kA at 690 V, making it suitable for high-fault-current installations like utility mains or large transformer secondaries.

What trip unit does the 3VA2140-0HM32-0AA0 use?

It uses the ETU330 electronic trip unit with adjustable settings and integral ground-fault monitoring via summation current formation on the L-conductor.

Where can I buy the 3VA2140-0HM32-0AA0 and get current pricing?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

Will the 3VA2140-0HM32-0AA0 drop into a panel designed for 3VA2140-8JQ32-0AA0?

Both are 3VA2 frame breakers with the same 86 mm depth, 105 mm width, and 181 mm height, so the mechanical footprint is identical. The difference is in the trip unit and accessories — verify the wiring scheme matches your application.
