Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that place it in a high-fault-duty bracket suitable for main or feeder positions in industrial switchboards where available fault current is substantial. The TM220 overcurrent release provides thermal-magnetic protection: the thermal element handles overloads with an inverse-time curve, while the magnetic element responds to short-circuits. ## Panel integration and mechanical fit Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — the width is a standard 4-inch (101.6 mm) footprint for a 4-pole MCCB, and the 70 mm depth keeps the breaker within typical enclosure clearances for backpanel or DIN-rail mounting (the SENTRON 3VA series uses a snap-on DIN-rail adapter for tool-less installation). Maximum power loss is 10.8 W at rated load — a modest figure that allows grouping multiple breakers in a panel without excessive thermal buildup, though the 40 A derating curve above 50 °C should be checked against the enclosure's internal ambient temperature.","metaTitle":"Siemens SENTRON 3VA1140-5EE46-0AA0 MCCB, 4-Pole, 40 A, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EE46-0AA0 molded case circuit breaker. 4-pole, 40 A rated at 40 °C, breaking capacity 187 kA at 240 V.
