That means you can set the short-time pickup and delay to coordinate with downstream MCCBs or fuses, avoiding nuisance trips on transformer inrush or motor starting. ## Communication capability This breaker includes a communication function — the ETU550 supports integration with SENTRON power management systems via the 3VA communication modules. That gives you remote trip indication, load current monitoring, and event logging without adding a separate power meter. If your panel spec calls for digital energy monitoring at the main breaker, this variant saves a DIN slot.","metaTitle":"Siemens 3VA2025-7JP42-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2025-7JP42-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU550 trip unit, 330 kA at 240 V.
