This breaker's interrupting ratings are given per voltage level — 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That spread matters because the same unit on a 415 V line handles a 52.5 kA fault, but on a 690 V circuit it's limited to 7.5 kA. ## Thermal derating and continuous current Rated 40 A from 40 °C up to 50 °C, then it starts to taper: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Plan your load accordingly; the nameplate 40 A is only good if the panel stays under 50 °C. ## Shunt trip and auxiliary release No undervoltage release fitted, no ground-fault monitoring. The TM210 overcurrent release handles the thermal-magnetic protection; the shunt trip is a separate add-on for emergency-off or interlock circuits.","metaTitle":"Siemens 3VA1040-3ED36-0KA0 SENTRON MCCB, 40A, 75.6kA at 240V","metaDescription":"Siemens 3VA1040-3ED36-0KA0 SENTRON molded case circuit breaker, 3-pole, 40A rated at 40°C, 75.6kA breaking capacity at 240V.
