Why Choose the ABB S803S-B40-R High Performance MCB?
The ABB S803S-B40-R is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. As part of the ABB S800S high-performance circuit breaker series, it combines high breaking capacity with robust modular construction for professional commercial and industrial circuit protection.
This circuit breaker has a rated current of 40 A and a Type B tripping characteristic. Type B protection is suited to circuits where substantial normal starting or inrush currents are not expected, providing sensitive magnetic short-circuit operation together with protection against sustained overload conditions.
With three protected poles and a short-circuit breaking capacity of 50 kA, the S803S-B40-R provides high-performance protection for installations where substantial prospective fault currents may occur. Its R variant, Type B characteristic and three-pole arrangement make it suitable for professional control, distribution and industrial electrical applications requiring dependable circuit protection.

High-Performance Type B Circuit Protection
Miniature circuit breakers protect electrical circuits against excessive current resulting from overloads and short circuits. The ABB S803S-B40-R combines overload protection with rapid magnetic short-circuit operation, automatically disconnecting the protected circuit when electrical conditions exceed the breaker's protective operating limits.
The Type B characteristic is appropriate for circuits where substantial normal inrush currents are not expected. Combined with the S800S platform's 50 kA short-circuit breaking capacity, the S803S-B40-R provides robust protection for demanding electrical distribution and control applications requiring a three-pole, 40 A protective device.
Typical Applications
- Three-phase electrical distribution circuits.
- Industrial control and auxiliary circuits.
- Commercial electrical installations.
- Industrial distribution boards and switchboards.
- Circuits with relatively low normal starting or inrush currents.
- Applications requiring high short-circuit breaking capacity.
