Breaking capacity varies significantly with line voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. For 690 V applications the available fault current must be verified against the 3.7 kA limit — this is not a general-purpose 690 V breaker for high-capacity circuits. The UVR ensures the breaker trips on loss of control voltage. Communication function is built in, supporting integration with higher-level monitoring systems without an external module. The trip indicator provides local visual status of the breaker state. Dimensions are 181 mm height, 140 mm width, and 86 mm depth. Width of 140 mm for a 4-pole MCCB is standard for the SENTRON 3VA2 frame; verify the mounting footprint matches the existing busbar or base plate if retrofitting. Maximum power loss is 4.1 W, which is negligible for enclosure thermal budgeting.","metaTitle":"Siemens 3VA2140-6KP42-0DK0 SENTRON MCCB, 40 A, 4-Pole, 242 k","metaDescription":"Siemens 3VA2140-6KP42-0DK0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, line protection.
