Why Choose the ABB S802S-D50 Miniature Circuit Breaker?
The ABB S802S-D50 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect cables, conductors and connected equipment against overloads and short circuits in demanding electrical installations. As part of the proven ABB S800S high-performance MCB series, it combines high fault-current interruption capability with a Type D tripping characteristic for circuits containing equipment with substantial starting or inrush currents.
With a rated current of 50 A and an ultimate short-circuit breaking capacity of 50 kA at 400 V AC, the S802S-D50 provides robust protection where high prospective fault currents must be safely interrupted. Its Type D characteristic is particularly suited to appropriately designed circuits supplying loads with high switch-on currents, helping prevent unwanted operation during normal equipment start-up while retaining effective overload and short-circuit protection.
The S802S-D50 uses a 2-pole configuration and is suitable for AC and DC applications within its specified ratings. Its current-limiting construction, high breaking performance and modular format make it a dependable choice for industrial distribution systems, machinery, control panels and other professional electrical installations.
