Above 50 °C it derates gradually: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. That's enough for a remote status indication — open/closed plus a separate trip signal — without adding an external contact block. The integrated auxiliary trip is order code 3VA9608-0BB24, in case you need to replace it separately. The 3VA1112-5MH36-0CH0 measures 130 mm high, 76.2 mm wide (3-pole), and 70 mm deep.","metaTitle":"Siemens 3VA1112-5MH36-0CH0 SENTRON MCCB, 125 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-5MH36-0CH0 molded case circuit breaker, 125 A rated current, 187 kA interrupting at 240 V.
