Product details

SENTRON 3VA2040-6HN36-0AA0 — 40 A MCCB with ETU350 Trip Unit

It carries an ETU350 electronic overcurrent release, which gives you adjustable long-time, short-time, and instantaneous pickup settings — not a fixed thermal-magnetic curve, so you can fine-tune coordination with downstream breakers on a distribution board or motor branch circuit. Interrupting capacity is substantial: 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V.

The 3VA2040-6HN36-0AA0 is a 3-pole breaker that mounts on DIN rail or direct panel. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — that's a 4.13 x 7.13 x 3.39 inch footprint.

The IP40 front rating means it's suitable for installation in a standard electrical enclosure with a door.

Frequently asked questions

Where can I buy 3VA2040-6HN36-0AA0 and what is the lead time?

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

What is the interrupting capacity of 3VA2040-6HN36-0AA0 at different voltages?

At 240 V it interrupts 242 kA, at 415 V and 440 V it interrupts 187 kA, at 500 V it interrupts 121 kA, and at 690 V it interrupts 3 kA.

Does 3VA2040-6HN36-0AA0 require derating at high ambient temperatures?

No derating needed — the breaker holds its full 40 A rating continuously from 40 °C through 70 °C ambient, so you can install it in a hot panel without oversizing.
