The 70 mm depth and 101.6 mm width fit standard SENTRON panel footprints, and the IP40 front protection suits enclosed distribution boards. ## Thermal-magnetic curve and derating The TM210 release holds 40 A continuously up to 50 °C ambient, derates to 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C — no derating needed in a standard 40 °C panel, but account for the drop in a hot enclosure.","metaTitle":"Siemens 3VA1040-2ED46-0AA0 4-Pole MCCB, 40 A, TM210, 52.5 kA","metaDescription":"Siemens SENTRON 3VA1040-2ED46-0AA0 molded case circuit breaker, 4-pole, 40 A, TM210 release, 52.5 kA at 240 V.
