The 25 A continuous rating holds flat from 40 °C to 50 °C, then derates to 24 A at 60 °C and 23 A at 70 °C. In a warm enclosure (55 °C internal), the breaker still carries 24 A without nuisance tripping — useful for tightly packed panels. The interrupting ratings span 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. That 53 kA at 415 V covers most European industrial supply points; the 12 kA at 500 V is adequate for 480 V North American systems where fault current rarely exceeds 10 kA. The TM220 release is a fixed thermal-magnetic trip — no interchangeable trip units, no electronic adjustments. Minimum continuous current is 18 A, so the breaker will not hold below that. Front IP40 protection means the face is sealed against tools and debris; the body is not rated for washdown. Four poles in a 101.6 mm footprint — that is a standard 4-module MCCB width for DIN-rail or screw-mount panels. Depth of 70 mm leaves room for rear busbar connections or cable glands without crowding the backplane.","metaTitle":"Siemens 3VM1125-3EE46-0AA2 SENTRON MCCB, 4-Pole, 25 A, 76 kA","metaDescription":"Siemens SENTRON 3VM1125-3EE46-0AA2 molded case circuit breaker, 4-pole, 25 A rated, 76 kA at 240 V.
