2CCS884001R0101 ABB S804C-D10 High Performance MCB 25 kA 4P Type D 10 A

Why Choose the ABB S804C-D10 High Performance MCB?

The ABB S804C-D10 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800C high-performance circuit breaker series, it combines high breaking capacity with a compact modular design for commercial and industrial electrical installations.

This circuit breaker features a D tripping characteristic and a rated current of 10 A, making it particularly suitable for circuits supplying equipment with high starting or inrush currents. Thermal tripping provides overload protection, while an electromechanical release provides rapid protection against short-circuit faults.

With four protected poles and an ultimate short-circuit breaking capacity of 25 kA at 240/415 V AC, the S804C-D10 provides robust protection where high prospective fault currents may occur. Its current-limiting operation and rapid arc extinction help reduce the thermal and mechanical stresses caused by short-circuit currents.

High-Performance Circuit Protection

The ABB S800C range is designed to protect cables, conductors and electrical equipment against overload and short-circuit currents where a high breaking capacity is required. Thermal overload protection works together with an electromechanical short-circuit release to provide effective protection across different fault conditions.

The D characteristic of the S804C-D10 makes it particularly useful for circuits containing equipment that can produce substantial starting currents, such as motors and transformers. Combined with its four-pole configuration, high breaking capacity and current-limiting design, the breaker is well suited to demanding commercial and industrial distribution systems.

Typical Applications

• Industrial electrical distribution systems.
• Machinery and automation control panels.
• Motor circuits with high starting currents.
• Transformer and inductive-load circuits.
• Commercial electrical installations.
• High-fault-level circuits requiring four-pole protection.
