At 415 V the 154 kA still covers most industrial main switchboards; the drop to 17 kA above 500 V is the limit of the TM220 release's magnetic blowout design, so for 690 V applications verify the available fault current is under that ceiling. ## Thermal derating and continuous current At 55 °C it drops to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. If the breaker sits next to high-wattage contactors or drives in a sealed enclosure, factor that 37 A floor at 70 °C into your bus sizing. ## Mechanical endurance and power loss Rated for 20,000 mechanical operations — that's a solid number for a line-protection MCCB that sees occasional switching, not daily motor starts. Maximum power loss is 10.8 W, which is modest for a 4-pole 40 A frame; it won't drive much additional cooling in a ventilated panel. Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a 4-pole MCCB that fits a standard 100 mm-wide DIN-rail or panel-mount footprint. It's a straightforward line-protection breaker: set it, wire it, forget it.","metaTitle":"Siemens 3VA1140-6EE46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 220 k","metaDescription":"Siemens 3VA1140-6EE46-0AA0 SENTRON molded case circuit breaker, 40 A rated, 4-pole, line protection, TM220 release, 220 kA at 240 V.
