Why Choose the ABB S803S-SCL63-SR MCB?
The ABB S803S-SCL63-SR is a high-performance 3-pole miniature circuit breaker (MCB) designed for demanding electrical distribution applications requiring effective overload and short-circuit protection. As part of the ABB S800S high-performance circuit breaker range, it combines a rated current of 63 A with a high 50 kA short-circuit breaking capacity.
The S803S-SCL63-SR is designed as a short-circuit limiting protective device, helping restrict the peak current and energy passed through during severe fault conditions. This current-limiting action helps reduce electrical and thermal stresses on conductors, busbars and connected equipment during short circuits.
Its 3-pole configuration makes the S803S-SCL63-SR well suited to three-phase industrial distribution systems. Combining a 63 A rating, high fault-interruption capability and short-circuit limiting functionality, it provides robust protection for professional switchboards, machinery and power distribution equipment.

High-Performance Short-Circuit Limiting Protection
Current-limiting circuit breakers are designed to interrupt severe short-circuit currents rapidly, restricting the peak fault current and energy allowed to pass through the protected circuit. This helps reduce the electrical and thermal stresses imposed on conductors, busbars and connected equipment during high-current faults.
The ABB S803S-SCL63-SR combines this short-circuit limiting function with a high 50 kA breaking capacity and three-pole construction, providing robust protection where substantial prospective fault currents may be present in three-phase industrial electrical systems.
Typical Applications
- Three-phase industrial electrical distribution systems.
- Machinery and automation control panels.
- Industrial switchboards and distribution boards.
- Three-phase power circuits.
- Installations with high prospective short-circuit currents.
- Applications requiring short-circuit limiting protection.
