Breaking capacity varies sharply with system voltage: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. At 55 °C it derates to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. In a sealed enclosure or a high-temp panel, use the 70 °C column: 37 A continuous is the real limit. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. Width at 101.6 mm (4 inches) is standard for a 4-pole frame — it occupies four 25 mm module positions on a DIN rail, though this is a bolt-on or screw-mount MCCB, not a snap-on MCB. Verify the mounting pattern against your backplate.","metaTitle":"Siemens 3VA1140-6GE46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 220 k","metaDescription":"Siemens 3VA1140-6GE46-0AA0 SENTRON molded case circuit breaker, 40 A fixed rating, 4-pole, breaking capacity 220 kA at 240 V.
