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.","metaTitle":"Siemens 3VA2040-7HL46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU32","metaDescription":"Siemens 3VA2040-7HL46-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, ETU320 trip unit, 330 kA at 240 V.
