Four poles let it switch three-phase plus neutral in a single envelope, saving a DIN row over separate breakers. The 25 A rating holds flat from 40 °C to 50 °C; above that it derates to 24 A at 55 °C and 60 °C, then 23 A at 65 °C and 70 °C. A panel OEM wiring a 24 A continuous load at 60 °C ambient needs to account for that step-down. Front IP40 protects against tool drops and dust ingress; the body is open-frame behind the panel, so clearance to live parts follows local wiring rules.","metaTitle":"Siemens 3VA1125-5ED46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1125-5ED46-0AA0 molded case circuit breaker, 25 A, 4-pole, TM210 release.
