It delivers a 187 kA interrupting capacity at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that matter when coordinating with upstream gear in a high-fault panel. The 125 A frame stays flat across the 40–50 °C band (125 A at 50 °C), then derates to 114 A at 70 °C, so it handles warm enclosure environments without oversizing. ## Line protection design The TM240 thermal-magnetic release handles overload and short-circuit. Power loss is 28.1 W maximum at rated current. ## Installation and compliance Mounts on a DIN rail or panel-mount baseplate with 76.2 mm width (3 in) and 130 mm height (5.12 in). Depth is 70 mm (2.76 in), which matters when the enclosure door clearance is tight.","metaTitle":"Siemens 3VA1112-5EF36-0AB0 MCCB, 125A, 3-Pole, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1112-5EF36-0AB0 molded case circuit breaker, 125A continuous, 3-pole, 187kA interrupting at 240V.
