The adjustable thermal-magnetic trip range is 38 A minimum to 300 A maximum, with a full-scale value of 25 A and an initial value of 15 A, giving flexibility for coordinating with downstream breakers. Power loss is only 0.5 W maximum, negligible for enclosure thermal calculations. Dimensions are 86 mm depth, 140 mm width, 181 mm height — fits a standard 4-pole MCCB footprint. The design includes a communication function for remote monitoring or trip indication, and a ground-fault monitoring version using summation current formation on L + N conductor. No undervoltage release or voltage trigger is built in, so if you need those, plan for external accessories.","metaTitle":"Siemens 3VA2025-7KQ46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2025-7KQ46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, breaking capacity 330 kA at 240 V.
