That simplifies panel design in warm enclosures or near heat-generating equipment — you don't have to oversize the frame for ambient temperature. It includes a communication function, which means it can report status and trip events to a higher-level control system over the plant network — useful for remote monitoring and predictive maintenance on critical feeders. Maximum power loss is 4 W, so heat dissipation inside the enclosure is minimal — one less variable to calculate in a dense panel.","metaTitle":"Siemens SENTRON 3VA2163-6KQ46-0AA0 MCCB, 63 A, 4-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2163-6KQ46-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, breaking capacity 242 kA at 240 V.
