ABB S803S-UCK63 is a 63 A three-pole Type K high-performance miniature circuit breaker with 50 kA short-circuit breaking capacity for demanding industrial and commercial circuit protection.
£280.63
The ABB S803S-UCK63 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding industrial and commercial installations. Part of the ABB S800S-UC high-performance circuit breaker range, it combines a 63 A rated current with a powerful 50 kA short-circuit breaking capacity.
Featuring a Type K tripping characteristic, the S803S-UCK63 is particularly suited to circuits supplying equipment with elevated starting or inrush currents. Its thermal-magnetic protection provides dependable overload and short-circuit protection while helping to reduce unwanted tripping during normal equipment starting conditions.
With its three-pole configuration, 63 A rated current and 50 kA breaking capacity, the S803S-UCK63 provides robust protection for three-phase machinery, motors and industrial distribution circuits. Its high-performance design makes it suitable for installations where substantial prospective fault currents require reliable interruption capability.
High-performance circuit breakers such as the ABB S803S-UCK63 automatically disconnect electrical circuits when excessive current results from overload or short-circuit conditions. Thermal protection responds to sustained overload currents, while magnetic protection provides rapid interruption when severe short-circuit faults occur.
The Type K characteristic is particularly useful for equipment that can draw elevated current during normal starting. Combined with the S803S-UCK63's 50 kA breaking capacity, this makes the breaker well suited to demanding three-phase industrial circuits where reliable fault protection and tolerance of normal inrush currents are important.
