Breaking capacity is 220 kA at 240 V AC, 154 kA at 415 V, and 121 kA at 440 V — numbers that put it in the high-interrupting category for industrial mains distribution. The shunt trip lets a remote safety relay or emergency-stop circuit open the breaker independently of the overload mechanism — standard for E-stop chains and undervoltage protection schemes. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting bases and busbar systems.","metaTitle":"Siemens 3VA1140-6EF32-0JA0 SENTRON MCCB, 40A 3-Pole, 220kA a","metaDescription":"Siemens SENTRON 3VA1140-6EF32-0JA0 molded case circuit breaker, 40A rated at 40°C, 3-pole, 220kA breaking capacity at 240V AC.
