Why Choose the ABB S804S-D40-R High Performance MCB?
The ABB S804S-D40-R is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance circuit breaker series, it combines a high breaking capacity with robust construction for commercial and industrial applications.
Featuring a Type D tripping characteristic, the S804S-D40-R is particularly suited to circuits where higher starting or inrush currents can occur. Thermal and electromagnetic tripping mechanisms provide protection against overload currents and short circuits, while ABB's current-limiting design and rapid arc extinction help minimise the effects of electrical faults.
With a rated current of 40 A, four-pole configuration and maximum ultimate short-circuit breaking capacity of 50 kA at 240/415 V AC, the S804S-D40-R provides high-performance circuit protection for installations requiring substantial fault-current capability. ABB order code 2CCS864002R0401 identifies this specific S800S variant.

High-Performance Circuit Protection
The ABB S800S range is engineered for installations where high short-circuit currents require greater breaking performance than conventional miniature circuit breakers. The S804S-D40-R combines thermal overload protection with electromagnetic short-circuit protection to safeguard conductors and connected electrical equipment.
Its Type D characteristic accommodates comparatively high transient and starting currents, making this breaker suitable for appropriate industrial loads where unwanted tripping during normal equipment start-up needs to be avoided. The four-pole arrangement enables simultaneous protection and switching across four conductors in compatible electrical distribution systems.
Typical Applications
- Industrial electrical distribution systems.
- Machinery and automation control panels.
- Circuits with high starting or inrush currents.
- Commercial and industrial switchboards.
- Motor and transformer-related circuits where a Type D characteristic is appropriate.
- High fault-level installations requiring enhanced breaking capacity.
