The interrupting ratings are the real headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That ground-fault feature is useful for detecting leakage on ungrounded or high-resistance-grounded systems without an external GF relay. ## Panel integration The 3-pole design means it occupies three module widths — plan for a 105 mm slot in your enclosure layout.","metaTitle":"Siemens 3VA2025-7KQ36-0AA0 SENTRON MCCB, 25 A, 3-pole, 330 k","metaDescription":"Siemens SENTRON 3VA2025-7KQ36-0AA0 molded case circuit breaker, 25 A continuous, 3-pole, adjustable thermal OL 38-300 A, 330 kA SCCR at 240 V.
