Why Choose the ABB S804S-D63 High-Performance MCB?
The ABB S804S-D63 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance circuit breaker series, it combines high fault-current interruption capability with robust construction for industrial and commercial installations.
This circuit breaker features a Type D tripping characteristic, making it particularly suitable for circuits supplying equipment with high starting or inrush currents. Its thermal and magnetic protection mechanisms provide dependable protection against sustained overloads and short-circuit faults, helping safeguard cables, equipment and downstream electrical systems.
With a rated current of 63 A, a four-pole configuration and a breaking capacity of 50 kA, the S804S-D63 provides robust circuit protection for installations where high prospective fault currents may occur. Its four-pole construction enables coordinated protection and switching across four conductors in compatible electrical distribution systems.

Reliable Protection for High-Inrush Circuits
Miniature circuit breakers such as the ABB S804S-D63 automatically disconnect protected circuits when excessive current occurs because of an overload or short circuit. Thermal protection responds to sustained overload conditions, while magnetic tripping provides rapid interruption when severe short-circuit currents occur.
The Type D characteristic is designed to tolerate comparatively high transient starting currents while maintaining effective fault protection. Combined with the high breaking capacity of the S800S platform, this makes the S804S-D63 particularly suitable for demanding machinery, motor, transformer and industrial distribution applications.
Typical Applications
- Industrial electrical distribution panels.
- Machinery and automation systems.
- Motor circuits with high starting currents.
- Transformers and other inductive loads.
- Industrial control and power distribution systems.
- Electrical installations requiring high fault-current protection.
