2CCS882001R0631 ABB S802C-D63 High Performance MCB 63 A 2P Type D 25 kA

Why Choose the ABB S802C-D63 High Performance MCB?

The ABB S802C-D63 is a high-performance two-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding commercial and industrial electrical systems. As part of the ABB S800C high-performance circuit breaker series, it combines compact DIN-rail installation with high breaking capacity for electrical distribution, machinery and automation applications.

This circuit breaker features a Type D tripping characteristic and a rated current of 63 A. The D characteristic is designed for circuits with high starting or inrush currents, making the S802C-D63 particularly suitable for motors, transformers and other inductive loads where substantial temporary current peaks can occur during normal start-up.

With a short-circuit breaking capacity of 25 kA, the S802C-D63 provides robust fault protection for installations with elevated prospective short-circuit currents. Its two-pole configuration provides simultaneous switching and protection, while the proven S800 construction supports dependable operation in distribution boards, machinery panels and industrial control systems.
