Why Choose the ABB S802S-UCB63-R High Performance MCB?
The ABB S802S-UCB63-R is a high-performance 2-pole miniature circuit breaker (MCB) designed specifically for demanding direct-current circuit protection. Part of the ABB S800S-UC range, it combines a 63 A rated current, UC-B tripping characteristic and high 50 kA short-circuit breaking capacity at 500 V DC.
The S802S-UCB63-R provides protection and control against overload and short-circuit conditions where high breaking capacity is required. Its UC-B characteristic is particularly suited to applications requiring sensitive magnetic tripping, including protection of people and long cable runs in TN and IT systems.
With a rated current of 63 A, a UC-B / Type B characteristic and both Icu and Ics ratings of 50 kA at 500 V DC, the S802S-UCB63-R provides robust two-pole protection for demanding DC systems. This version uses ring tongue terminals and is also suitable where selectivity with an upstream MCCB or back-up protection for downstream MCBs is required.
