2CCG001271R0001 ABB S803P-C80-R High Performance MCB 50 kA 3P Type C 80 A Ring-Lug

Why Choose the ABB S803P-C80-R High Performance MCB?

The ABB S803P-C80-R is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the ABB S800P high-performance circuit breaker series, it provides a high breaking capacity for demanding commercial and industrial electrical installations.

This R version of the S803P-C80 uses ring-lug terminal connections. Its Type C tripping characteristic is designed for resistive and inductive loads with relatively low inrush currents, while the S800P platform is particularly useful where selectivity with an upstream MCCB or back-up protection for downstream MCBs is required.

With a rated current of 80 A, three protected poles and a rated ultimate short-circuit breaking capacity (Icu) of 50 kA at 415 V AC, the S803P-C80-R provides robust circuit protection where high prospective fault currents are present. Its ring-lug connection arrangement makes it suitable for installations where secure cable-lug termination is required.

High Breaking Capacity Protection with Ring-Lug Connections

High-performance miniature circuit breakers such as the ABB S803P-C80-R automatically disconnect electrical circuits when excessive current occurs. Thermal protection responds to sustained overload conditions, while electromagnetic protection operates rapidly during short-circuit conditions, helping protect cables, conductors and connected equipment from damaging fault currents.

The Type C characteristic is suitable for resistive and inductive circuits with relatively low inrush currents. Combined with an 80 A rating, three-pole construction, 50 kA ultimate breaking capacity at 415 V AC and ring-lug terminals, the S803P-C80-R provides a high-performance protection solution for demanding commercial and industrial distribution systems.

Typical Applications

• Commercial and industrial electrical distribution systems.
• Three-phase distribution and feeder circuits.
• Resistive and inductive loads with relatively low inrush currents.
• Industrial machinery and electrical equipment.
• Electrical switchboards and distribution panels.
• Installations requiring ring-lug cable connections.
• Systems requiring selectivity or back-up protection between circuit breakers.
