Its interrupting capacity hits 187 kA at 240 V AC — that's the number to check against your available fault current on the line side; at 415 V it still holds 121 kA, and at 500 V it drops to 17 kA, so verify the voltage class at the point of installation. ## Dimensions & Panel Fit Depth is 70 mm, width 101.6 mm, height 130 mm. Fits standard DIN-rail or panel-mount cutouts for a 4-pole MCCB in the SENTRON 3VM frame. Check the mounting footprint against your existing busbar or terminal block layout — the 101.6 mm width is a common 4-inch pitch, so it aligns with standard distribution panel spacing. ## Thermal Derating & Operating Range","metaTitle":"Siemens SENTRON 3VM1125-5EE42-0AA0 MCCB, 25 A, 4-pole, 187 k","metaDescription":"Siemens SENTRON 3VM1125-5EE42-0AA0 molded case circuit breaker, 25 A rated, 4-pole, interrupting capacity 187 kA at 240 V.
