Its interrupting capacity hits 187 kA at 240 V AC and 121 kA at 415 V AC, so it handles high-fault service-entrance or sub-distribution positions without cascading upstream breakers. The ETU320 electronic trip unit provides adjustable overload and short-circuit protection curves, suited for line protection in motor branch circuits or feeder applications where coordination selectivity matters. At 86 mm deep, 105 mm wide, and 181 mm tall, it fits standard SENTRON 3VA2 panel cutouts and busbar arrangements — a direct swap for any 3-pole 40 A frame in the series. ## Integration notes for the panel builder Front face carries IP40 protection — suitable for enclosed panel mounting where no washdown or dust ingress is expected. Rated insulation voltage Ui is 800 V AC; operational voltage is 690 V AC. No undervoltage release, no shunt trip, no ground-fault monitoring, and no communication module on this variant — it is a straight line-protection breaker with the ETU320 trip unit only. Power loss at rated current is 1.6 W maximum — negligible for thermal budgeting inside a crowded panel.","metaTitle":"Siemens 3VA2140-5HL32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU32","metaDescription":"Siemens 3VA2140-5HL32-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU320 release, 187 kA at 240 V.
