Why Choose the ABB S803N-B20 High-Performance MCB?
The ABB S803N-B20 is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect demanding electrical installations against overloads and short circuits. As part of the ABB S800N high-performance circuit breaker series, it combines a rated current of 20 A, Type B tripping characteristic and a high 36 kA breaking capacity for commercial and industrial circuit protection.
The S803N-B20 provides dependable current-limiting protection in installations where high prospective short-circuit currents may occur. Its Type B characteristic is suitable for appropriate circuits with relatively low starting or inrush currents, while its three-pole configuration enables simultaneous protection and switching of three-phase circuits.
With its compact modular construction and robust S800 platform, the S803N-B20 is well suited to industrial distribution boards, machinery, automation equipment and control panels. ABB order code 2CCS893001R0205 identifies this specific 20 A, 3-pole Type B version.
