Breaking capacity is rated per the voltage it sees: 242 kA at 240 V AC, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. ## Thermal performance — no derating across the operating range No derating curve to calculate for panel internal temperatures up to 70 °C — the breaker is rated flat across that band. Footprint is 140 mm wide × 181 mm high × 86 mm deep (5.51 × 7.13 × 3.39 in). The 4-pole width at 140 mm is standard for a 4-pole MCCB frame in this class; verify the mounting base cutout and bus-bar spacing against the existing panel layout before ordering.","metaTitle":"Siemens 3VA2140-6HM46-0AA0 SENTRON MCCB, 4P, 40A, 60-480A Ad","metaDescription":"Siemens 3VA2140-6HM46-0AA0 SENTRON molded case circuit breaker, 4-pole, 40 A continuous, adjustable thermal trip 60-480 A, 242 kA at 240 V.
