Its interrupting rating reaches 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, and 187 kA at 500 V — numbers that tell you this breaker is built for high-fault-capacity distribution panels where selective coordination matters. ## Panel fit and mounting — 105 mm wide, DIN-rail compatible Mounting is via the integral DIN-rail clip — no adapter plate needed for most enclosures. Storage limits span -40 °C to 80 °C. Maximum power loss is 0.6 W — negligible for panel thermal budgeting.","metaTitle":"Siemens 3VA2125-7HN36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 330 k","metaDescription":"Siemens 3VA2125-7HN36-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 3-pole, 330 kA interrupting at 240 V.
