The steep drop at 690 V tells you this is a 240–500 V primary-rated device; at 690 V it still clears, but coordination studies should use the 3 kA figure. The 4-pole frame measures 140 mm wide by 181 mm high by 86 mm deep — a standard SENTRON 3VA footprint that fits existing DIN-rail or screw-mount panel layouts. The ETU850 trip unit supports communication and measurement functions, so plan for a wiring path to the control system if you're using those features.","metaTitle":"Siemens 3VA2025-6KP42-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2025-6KP42-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU850 electronic trip unit.
