The front face is rated IP40, suitable for enclosed panel mounting. ## Selectivity and SCCR headroom With 187 kA at 240 V, this MCCB coordinates downstream in high-fault panels where a standard 25 A frame would otherwise cascade. The 121 kA at 415 V covers most 400 V industrial feeds, while the 75.6 kA at 440 V suits North American 480Y/277 V systems. The 17 kA at 690 V rating allows use in 690 V drives or mining distribution. For a panel originally specified around the 3VA1110-5EE32-0JA0 (a 10 A frame), the 3VA1125-5EF36-0HH0 has the same 3-pole footprint and similar auxiliary contact options, but at 25 A continuous — verify the upstream breaker coordination and cable sizing before substitution. Mounts in a standard distribution panel or motor control center. The 70 mm depth, 76.2 mm width, and 130 mm height fit the SENTRON 3VA family cutout. Front IP40 allows flush mounting in IP54 enclosures with a gasketed door. The shunt trip (STL) and auxiliary switches (2 + 1 alarm) terminate on the breaker body; wire per the 3VA9688-0BL30 auxiliary trip wiring diagram.","metaTitle":"Siemens 3VA1125-5EF36-0HH0 SENTRON MCCB, 25 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1125-5EF36-0HH0 molded case circuit breaker, 25 A rated, 187 kA at 240 V interrupting capacity.
