Its interrupting capacity reaches 75.6 kA at 240 V and 52.5 kA at 415 V — figures that define the maximum fault current it can safely clear without upstream coordination failure. At 440 V the rating drops to 32 kA, and at 500 V and 690 V it holds at 7.5 kA. The TM210 release provides thermal protection for overloads and magnetic (instantaneous) protection for short-circuits. This is typical for motor feeder circuits where a momentary loss of supply should not cause an uncontrolled restart. The 40 A rating holds up to 50 °C ambient. Above that, derating applies: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. For a panel running at 60 °C, the breaker is effectively a 37.6 A device — plan the load accordingly. The 3VA frame width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That footprint matches the standard SENTRON 3VA mounting pattern, so it drops into existing DIN-rail or panel-mount cutouts without re-drilling. Maximum power loss is 13.3 W.","metaTitle":"Siemens 3VA1040-3ED36-0BA0 SENTRON MCCB, 40 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1040-3ED36-0BA0 molded case circuit breaker, 40 A rated at 40 °C, 3-pole, interrupting rating 75.6 kA at 240 V.
