It carries an interrupting capacity of 330 kA at 240 V, dropping to 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. That 330 kA figure at 240 V makes it suitable for high-fault service-entrance or large-bus applications where upstream SCCR requirements are extreme. ## Trip unit and communication The overcurrent release is the ETU550 — an electronic trip unit with communication capability, as indicated by the Communication Function flag. This allows integration into a power-monitoring or energy-management system without an external add-on module. The breaker is configured for line protection (not feeder or motor protection), so the trip curves are set for cable and busbar thermal limits. Maximum power loss is 63.5 W, which should be factored into panel thermal calculations when grouping multiple breakers.","metaTitle":"Siemens 3VA2440-7JP32-0AA0 SENTRON MCCB, 400 A, 3-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2440-7JP32-0AA0 molded case circuit breaker, 400 A, 3-pole, ETU550 trip unit, 330 kA at 240 V.
