At 240 V it interrupts 121 kA; at 415 V it still holds 75.6 kA. Those numbers drop to 52.5 kA at 440 V and 11.9 kA at both 500 V and 690 V — so for a 480 V panel you are working with 52.5 kA of interrupting rating, which covers most industrial service-entrance and feeder applications. Four-pole width means it occupies four module spaces on a DIN rail — plan the gland plate and busbar drop accordingly. IP40 on the front keeps dust out of the mechanism; no special sealing for washdown environments. Power loss is 38 W at full load. That heat has to leave the enclosure — in a sealed stainless cabinet you will want to check the thermal rise against the 70 °C operating maximum and the -25 °C minimum.","metaTitle":"3VA1116-4FF42-0AA0 SENTRON MCCB, 4P 80A TM240, 121kA@240V","metaDescription":"Siemens SENTRON 3VA1116-4FF42-0AA0 molded case circuit breaker, 4-pole, 80 A, TM240 release, 121 kA breaking capacity at 240 V.
