It carries an ETU850 electronic trip unit, which gives you adjustable long-time, short-time, instantaneous, and ground-fault protection curves. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That kind of fault-clearing capacity means it can serve as a main or feeder breaker in high-fault panels without cascading upstream. That simplifies panel design in warm enclosures or near other heat sources. The ETU850 electronic release is programmable, so you can shape the trip curve to coordinate with downstream breakers or fuses. ## Panel Integration The communication function (listed as Yes) means it can interface with a higher-level system for monitoring or remote trip indication, though the exact protocol depends on the communication module you pair with it.","metaTitle":"Siemens SENTRON 3VA2063-7KP42-0AA0 MCCB, 63 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2063-7KP42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU850 release, 330 kA at 240 V.
