Why Choose the ABB S803S-D5 High Performance MCB?
The ABB S803S-D5 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial, commercial and electrical distribution applications. As part of the ABB S800S high-performance MCB series, it combines current-limiting technology with a high breaking capacity for circuits where substantial prospective fault currents may occur.
This circuit breaker has a 5 A rated current and Type D tripping characteristic. It incorporates thermal tripping for overload protection together with electromechanical tripping for short-circuit protection. The Type D characteristic is particularly suited to appropriately designed circuits supplying loads with high starting or inrush currents.
The S803S-D5 is a 3-pole device with a maximum breaking capacity of 50 kA. Its interchangeable cage-terminal design and compact modular construction make it suitable for integration into switchboards, electrical distribution systems, machinery and industrial control panels.

High-Performance Circuit Protection for Demanding Installations
High-performance miniature circuit breakers such as the ABB S800S protect conductors and connected equipment against overload and short-circuit currents. The current-limiting design rapidly interrupts severe fault currents, helping reduce the electrical and thermal stresses imposed on downstream equipment and conductors.
The S803S-D5 combines three-pole protection with a Type D characteristic, making it suitable for appropriately engineered circuits where normal equipment start-up can create significant transient currents. Its high breaking capacity makes the device particularly useful in industrial distribution systems where conventional MCB breaking capacities may be insufficient.
