The breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — covering most low-voltage fault scenarios in industrial and commercial installations. ## Physical Fit and Mounting The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — standard for a 3VA2 frame. Verify the panel cutout and busbar spacing against these dimensions before ordering; the 105 mm width is the same as other 3VA2 3-pole units, so a panel laid out for a sibling like the 3VA2125-8KQ42-0AA0 should accept this one without rewiring — same frame, same footprint.","metaTitle":"Siemens 3VA2025-5KP36-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU85","metaDescription":"Siemens 3VA2025-5KP36-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 3-pole, ETU850 electronic trip unit, breaking capacity 187 kA at 240 V.
