Product details

SENTRON 3VA2040-5JP42-0AA0 — 40 A MCCB with ETU550 Trip Unit

It carries an ETU550 electronic trip unit, adjustable from 60 A minimum to 480 A maximum — the 40 A frame rating means the trip unit's continuous current rating is set at 40 A, with the adjustable overload pickup range starting above that value. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V, giving it headroom for high-fault installations.

Panel Integration

Mounts via screw terminals to a backplate or DIN rail adapter; the 4-pole unit occupies the same width as four single-pole spaces in a typical panel layout.
