The ETU330 electronic trip unit provides adjustable long-time (Ir) and ground-fault (Ig) response, both settable up to 800 A, with time delays from 0.5 to 17 s. This is a line-protection device, not a motor-protection breaker; it guards feeders and main switchboards against overload and short-circuit faults. That thermal stability is unusual; many MCCBs start tapering at 40 °C. The 4-pole design with adjustable N-conductor protection (OFF, 50%, 100%) suits three-phase-plus-neutral systems where the neutral may carry harmonic currents. The ETU330 release supports ground-fault summation via the L+N conductor, so it can detect residual currents without a separate core-balance CT. The breaker measures 280 mm wide, 320 mm high, and 120 mm deep. The 135 W maximum power loss must be factored into the enclosure thermal budget; at full load the heat dissipation is comparable to a small drive. The ETU330 is self-powered from the line side, so no auxiliary supply is needed for the trip unit. Communication function is not fitted on this variant (no Modbus or PROFIBUS module), so status and trip data are local only.","metaTitle":"Siemens 3VA2580-7HM42-0AA0 SENTRON MCCB, 800 A, 4-pole, 242","metaDescription":"Siemens SENTRON 3VA2580-7HM42-0AA0 molded case circuit breaker, 800 A rated continuous current, 4-pole, 242 kA at 415 V, ETU330 release.
