Product details

That's unusual for an MCCB; most thermal-magnetic units start dropping at 50 °C. The ETU320 electronic trip keeps the threshold stable across the panel's internal temperature rise. At 690 V it still clears 187 kA, which covers most 480/600 V industrial services in North America and 690 V European distribution.

Panel integration

Front IP40 protects against solid objects larger than 1 mm; the interior of the panel needs to be kept clean of dust and moisture. Optional motor drive for remote operation is supported.

Frequently asked questions

What is the breaking capacity of this MCCB?

440 kA at 415 V AC and 187 kA at 690 V AC. That's the ultimate short-circuit breaking capacity (Icu) — it can clear a fault at that level and still be reused.

Where can I buy 3VA2140-0HL36-0AA0?

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

What trip unit does this breaker use?

The ETU320 electronic trip unit with LI protection (long-time and instantaneous). It's designed for line protection — cable and busbar, not motor overload.
