Breaking capacity — what those numbers mean for fault duty
This breaker's interrupting capacity climbs with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. At typical 480 V industrial distribution, it clears 187 kA of prospective fault current — that's well above what most service-entrance panels see, so it's sized for high-fault locations like substation feeders or large motor control centers.
Mounting dimensions and panel fit
The 3VA2040-7HL46-0AA0 measures 140 mm wide, 181 mm tall, and 86 mm deep — a standard 4-pole MCCB footprint that drops into SENTRON 3VA2 switchgear or any DIN-rail-mounting panel with the right adapter.
What the ETU320 trip unit gives you
It draws a maximum power loss of 1.2 W.
Temperature range and storage handling
What this breaker does not include
If your safety circuit requires undervoltage protection or remote tripping, you'll need an accessory add-on or a different 3VA2 variant. The line protection design means it's set up for feeder duty out of the box — not for motor-starting applications that need a higher magnetic pickup or adjustable time-delay curves.
