The headline interrupting rating is 440 kA at 240 V, dropping to 330 kA at 415 V and 440 V, then 220 kA at 500 V, and 53 kA at 690 V. It ships with an ETU550 electronic trip unit — that's the programmable overcurrent release that lets you dial in long-time pickup, short-time delay, and instantaneous thresholds. The adjustable response time for the short-time delay (tsd) ranges from 0 to 0.5 s, and the long-time ramp (tr) is adjustable between 0.5 and 25 s. That flexibility is what makes this breaker suitable for selective coordination downstream of a main breaker: you can delay the trip long enough to let a branch device clear a fault first. ## Where it fits — panel integration and environment That's typical for a panel-mounted MCCB; the enclosure itself carries the overall IP rating. Maximum power loss is 3 W. Communication function is built in (yes), which means the ETU550 can interface with a communication module for remote monitoring and trip-event logging — useful if you're building a smart panel with power monitoring upstream.","metaTitle":"Siemens 3VA2063-8JP32-0AA0 SENTRON MCCB, 63 A, 440 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-8JP32-0AA0 molded case circuit breaker, 3-pole, 63 A rated current, 440 kA interrupting at 240 V.
