The ETU550 electronic trip unit lets you set the overload threshold anywhere from 60 A to 480 A, which means one SKU covers multiple load sizes on the BOM. Breaking capacity runs 440 kA at 240 V, 330 kA at 415/440 V, 220 kA at 500 V, and 52.5 kA at 690 V — high enough for most distribution and motor branch circuits without an upstream current-limiting fuse. The ETU550 supports communication functions, so you can pull trip events and load data into a BMS or PLC without adding a separate meter.","metaTitle":"Siemens 3VA2040-8JP32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2040-8JP32-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU550 electronic trip, adjustable 60-480 A.
