The 3-pole design handles three-phase loads, and the ETU560 electronic trip unit gives you adjustable time-current curves (tr from 0.5 to 25, tsd up to 0.5 s) for selectivity downstream. This MCCB's interrupting rating is specified at multiple system voltages: 440 kA at 240 V, 330 kA at both 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. The 53 kA at 690 V is still well above typical industrial SCCR requirements; you are not bumping into limits even on 690 V mining or marine supplies. ## Thermal performance and enclosure planning Power loss is only 1.2 W maximum, so heat buildup inside the enclosure is minimal. ## Communication and monitoring capability That means you can integrate it into a higher-level monitoring system — useful for predictive maintenance or remote trip indication. The ETU560 release allows adjustable response times for both long-time (tr) and short-time (tsd) protection, giving you selectivity coordination with downstream breakers.","metaTitle":"Siemens 3VA2040-8JQ32-0AA0 SENTRON MCCB, 40 A, 3-Pole, 440 k","metaDescription":"Siemens 3VA2040-8JQ32-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, breaking capacity 440 kA at 240 V.
