This breaker clears 330 kA at 240 V, 242 kA at 415/440 V, and still holds 187 kA at 500 V. The adjustable overload trip range spans 38 A minimum to 300 A maximum, with a 15 A initial value and full-scale set at 25 A. No need to uprate for a hot panel top. Power loss is negligible at 0.5 W max — won't heat up a sealed enclosure. ## Panel fit — footprint and integration Dimensions: 86 mm deep, 105 mm wide, 181 mm tall — or 3.39 × 4.13 × 7.13 inches. The closest functional peer is 3VA2025-8HM42-0AA0. Both are 3-pole, 25 A SENTRON MCCBs with the same line-protection design. The -7HM32 lacks a trip indicator and undervoltage release that the -8HM42 may include.","metaTitle":"Siemens 3VA2025-7HM32-0AA0 SENTRON MCCB, 25 A, 3-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2025-7HM32-0AA0 molded case circuit breaker. 25 A continuous, 3-pole, 330 kA breaking at 240 V.
