Thermal current rating holds at 40 A from 40 °C through 50 °C, then derates to 38.4 A at 55 °C and 36 A at 70 °C. ## Auxiliary Circuit Configuration and Release Options No undervoltage release is fitted, so the breaker does not drop out on voltage sag; if UVR protection is needed, select a different suffix. The trip indicator and voltage trigger are present, confirming visual and electrical trip indication. The 76.2 mm width matches the 3-pole modular pitch for SENTRON 3VA breakers, so it occupies three 25.4 mm (1-inch) module spaces.","metaTitle":"3VA1040-3ED36-0KH0 SENTRON MCCB, 40A, 3-Pole, 75.6kA at 240V","metaDescription":"3VA1040-3ED36-0KH0 SENTRON molded case circuit breaker, 40A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
