The IP40 front protection means it's rated for indoor panel installation where tools or fingers might contact the front face; no condensation or dripping water exposure allowed on the front. ## Thermal derating and endurance — real-world limits The 63 A rating holds flat to 50 °C ambient. Above that it derates linearly: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. Mechanical endurance is rated at 20,000 cycles — that's typical for a distribution MCCB, not a motor-switching contactor; expect it to last the life of the installation in a feeder role with infrequent manual switching. Maximum power loss is 4 W at rated current — negligible for panel thermal calculations, but worth noting if you're packing multiple breakers in a small enclosure with no forced ventilation.","metaTitle":"Siemens SENTRON 3VA2163-5KP32-0AC0 MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5KP32-0AC0 molded case circuit breaker, 63 A rated continuous current, 187 kA interrupting at 240 V, 3-pole, ETU850 trip unit, IP40 front.
