Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that place it in the high-fault-current class for industrial main feeders and large sub-distribution boards. A mechanical trip indicator is present on the front face. Above that, it derates linearly: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth, which fits the standard SENTRON 3VA mounting footprint on a DIN rail or screw-fixed backplate. The TM240 release provides thermal protection for overloads and magnetic (instantaneous) protection for short circuits. For DC network applications, the manufacturer directs to the 3VA device manual for specific switching power values — this variant is primarily an AC line protection device.","metaTitle":"Siemens 3VA1150-6EF36-0BH0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0BH0 molded case circuit breaker, 50 A rated, 220 kA breaking at 240 V.
