Its interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. Its dimensions — 105 mm wide, 181 mm tall, 86 mm deep — mean it occupies a standard 3-pole MCCB footprint, so it drops into an existing SENTRON or 3VA-series panel layout without re-drilling the backplate.","metaTitle":"Siemens 3VA2125-5JP36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2125-5JP36-0AA0 molded case circuit breaker, 25 A rated, 3-pole, 187 kA breaking at 240 V.
