2CCS863002R0084 ABB S803S-C8-R 8A 3-Pole Type C 50kA MCB

Why Choose the ABB S803S-C8-R High-Performance MCB?

The ABB S803S-C8-R is a high-performance three-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance circuit breaker range, it combines a rated current of 8 A, Type C tripping characteristic and high short-circuit performance for industrial, commercial and automation applications.

The S803S-C8-R uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment against sustained overloads and short-circuit faults. Its current-limiting design rapidly interrupts high fault currents, helping reduce thermal and electrodynamic stresses on downstream components while providing reliable protection in installations with high prospective fault levels.

With a three-pole configuration, 8 A rated current and Type C characteristic, the S803S-C8-R is suitable for circuits with moderate starting or inrush currents. Its 50 kA short-circuit breaking capacity makes it a robust choice for professional electrical distribution and machinery applications.

Reliable Protection for Industrial Circuits

The ABB S800S range is engineered for electrical installations requiring high short-circuit performance and dependable protection against electrical faults. The S803S-C8-R automatically disconnects the protected circuit when overload or short-circuit conditions occur, helping safeguard conductors, machinery and downstream electrical equipment.

Its Type C characteristic provides a practical balance between fault sensitivity and tolerance of moderate temporary inrush currents. This makes the S803S-C8-R suitable for many industrial control circuits, machinery, small motors and other equipment where normal energisation can produce short-duration current peaks.
