Rated 25 A continuously at 40 °C ambient, it holds that rating through 50 °C and only begins a gentle derating curve above that — 24 A at 55 °C, 23 A at 70 °C — which is typical for a compact MCCB and means you don't have to oversize for a warm enclosure. The headline breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V. The IP40 protection on the front means it's splash-proof against tools and fingers but not washdown — standard for an enclosed panel mount. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall, which is the 3VA frame size footprint; it bolts into the same busbar and mounting pattern as other 3VA breakers in this frame class. The 3VA1125-5EE36-0AA0 mounts via screw terminals to a busbar or panel backplate — it's a bolted-frame MCCB, not a DIN-rail snap-on. Depth of 70 mm leaves clearance for rear-connected busbars and cable bend radius. The IP40 front means it's fine in a ventilated enclosure but not outdoors or in washdown zones. ## What it does not include It is a straight thermal-magnetic MCCB — no electronics, no aux contacts built in. If you need remote tripping or status feedback, you add external accessories (shunt trip, auxiliary switch) that fit the 3VA accessory slot.","metaTitle":"Siemens 3VA1125-5EE36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1125-5EE36-0AA0 SENTRON molded case circuit breaker, 25 A rated at 40 °C, 3-pole, 187 kA breaking at 240 V.
