The interrupting capacity tells the story: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. Front face carries IP40 protection. Communication function is built in. The 3-pole form factor with adjustable N-conductor protection (OFF, 40 % to 160 %) means it can serve as a main or feeder breaker in a 3-phase 4-wire panel where the neutral needs protection coordination. The IP40 front is adequate for a deadfront enclosure; keep it behind a sealed door if the panel sees dust or dripping water.","metaTitle":"Siemens 3VA2025-5KP32-0AA0 SENTRON MCCB, 25 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2025-5KP32-0AA0 molded case circuit breaker, 25 A, 3-pole, 187 kA at 240 V.
