Its interrupting capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — figures that place it in the high-fault-current class for industrial distribution panels where upstream transformer capacity or fault current is substantial. The ETU850 electronic overcurrent release provides adjustable time-current curves: tr from 0.5 s to 25 s, tsd up to 0.5 s, giving the commissioning engineer room to coordinate with downstream breakers without nuisance tripping. Front face protection is IP40, suitable for enclosed panel installation where no washdown or dust ingress is expected. Rated insulation voltage Ui of 800 V; operating temperature range from -40 °C to 70 °C, storage from -40 °C to 80 °C. Mechanical endurance of 20 000 cycles and a maximum power loss of 2.2 W per pole indicate a design suited for frequent switching applications where heat dissipation in the enclosure matters. Communication function and other measurement function are present on this variant, allowing integration with energy management systems via the SENTRON communication platform.","metaTitle":"Siemens 3VA2040-6KP36-0AA0 SENTRON MCCB, 40 A, 242 kA at 240","metaDescription":"Siemens 3VA2040-6KP36-0AA0 SENTRON molded case circuit breaker, 3-pole, 40 A, 242 kA interrupting at 240 V, ETU850 release.
