At 415 V and 440 V it still holds 121 kA, and at 500 V it drops to 75.6 kA. The steep cliff at 690 V (3 kA) tells you this is a low-voltage distribution breaker, not a motor-circuit device; if your system runs 690 V, this frame is the wrong choice. Dimensions are 140 mm wide, 181 mm high, 86 mm deep — a standard 4-pole MCCB footprint for the 3VA frame. Communication function is built in (: yes), which on the 3VA platform means the ETU550 can interface with a COM module for remote trip indication, power monitoring, or load shedding via PROFIBUS or PROFINET. No separate power supply needed for the trip unit — it's self-powered from the line current above a few amps. Power loss is 0.84 W maximum — negligible for thermal budgeting inside the panel, but it confirms the electronic trip unit draws very little heat compared to a thermal-magnetic breaker at the same current.","metaTitle":"Siemens 3VA2025-5JP42-0AA0 SENTRON MCCB, 25A, 4P, ETU550, 18","metaDescription":"Siemens SENTRON 3VA2025-5JP42-0AA0 molded case circuit breaker, 25A continuous, 4-pole, ETU550 trip unit.
