The current rating holds flat at 25 A from 40 °C through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. The breaker measures 70 mm deep by 101.6 mm wide by 130 mm high. It's a panel-mount device, not a snap-on DIN rail unit — plan for screw-mounting on a backplate or mounting plate. Four poles let it switch all three phases plus neutral in a TN or TT system. There's no integrated N-conductor protection (separate neutral protection needed if required by local code), no undervoltage release, no communication module, and no ground-fault monitoring — this is a straight thermal-magnetic breaker, no electronics. Maximum power loss is 8.5 W — a modest figure that won't drive significant heat buildup in a well-ventilated enclosure, but worth noting if you're packing multiple breakers into a small dead-front panel.","metaTitle":"Siemens 3VA1125-3ED46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1125-3ED46-0AA0 SENTRON molded case circuit breaker, 25 A rated, 4-pole, TM210 release, breaking capacity 75.6 kA at 240 V AC.
