For a 40 A frame, those numbers give you wide selectivity margins downstream — you can coordinate with smaller branch breakers without worrying about nuisance tripping on a fault upstream. The ETU550 electronic trip unit is adjustable, with short-time delay (tsd) settings from 0.5 s to 0.5 s, and thermal memory for repeated faults. Communication function is built in, which simplifies integration with a BMS or power monitoring system without an external module.","metaTitle":"Siemens 3VA2040-8JP36-0AA0 SENTRON MCCB, 40 A, 3-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2040-8JP36-0AA0 molded case circuit breaker, 40 A rated continuous, 3-pole, interrupting up to 440 kA at 240 V.
