The breaking capacity hits 440 kA at 415 V and 187 kA at 690 V — that means it can safely clear a fault current up to those levels without the arc flashing over or the case rupturing, which is what you need when the available short-circuit current on the bus is high. The continuous current rating of 25 A holds across the full ambient range from 40 °C to 70 °C — no derating needed for elevated panel temperatures, which simplifies panel design in hot environments like boiler rooms or enclosed switchgear. The minimum setting is 38 A, so this breaker is sized for a feeder or branch circuit where the load current stays between 38 A and 300 A maximum. Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into a DIN-rail or panel-mount enclosure without surprises. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Power loss is a negligible 0.5 W maximum, so no special ventilation is needed.","metaTitle":"Siemens 3VA2125-0HL32-0AA0 MCCB, 25 A, 440 kA at 415 V","metaDescription":"Siemens SENTRON 3VA2125-0HL32-0AA0 molded case circuit breaker, 25 A continuous, 440 kA breaking at 415 V, ETU320 release.
