Product details

Siemens SENTRON 3VA2140-7JP42-0AA0 — 40 A MCCB with ETU550

It carries an ETU550 electronic trip unit, adjustable from 60 A to 480 A — so the 40 A frame can be wired for a downstream load up to 480 A by swapping the trip rating, though the continuous rating on this specific variant is 40 A. Breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so this breaker is best applied on 240–500 V systems where its SCCR headroom is substantial.

The breaker includes a communication function for remote monitoring and trip indication without a separate voltage trigger.
