Rated current holds at 25 A from 40 °C through 50 °C ambient, then derates to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C. The interrupting curve drops sharply with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. For a 480 V panel, the 75.6 kA figure governs your SCCR coordination study. The 76.2 mm width (3 in) is the standard 3-pole MCCB footprint for this frame size; it occupies three 25 mm DIN positions if mounted on a DIN rail, or bolts directly to a mounting plate.","metaTitle":"Siemens 3VA1125-5ED32-0AA0 SENTRON MCCB, 25 A, 3-Pole, TM210","metaDescription":"Siemens 3VA1125-5ED32-0AA0 SENTRON molded case circuit breaker, 25 A at 40 °C, 3-pole, TM210 release, 187 kA at 240 V.
