2CCS864002R0061 ABB S804S-D6-R 6 A 4-Pole Type D High-Performance MCB 50 kA

Why Choose the ABB S804S-D6-R High-Performance MCB?

The ABB S804S-D6-R 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 conductors, equipment and downstream electrical systems.

With a rated current of 6 A, a four-pole configuration and a breaking capacity of 50 kA, the S804S-D6-R 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.

Key Advantages

• High-performance four-pole miniature circuit breaker for demanding electrical installations.
• 6 A rated current for industrial and commercial circuit protection.
• Type D tripping characteristic suitable for circuits with high starting or inrush currents.
• High 50 kA breaking capacity for installations with significant prospective fault currents.
• Thermal and magnetic protection against overloads and short circuits.
• Four-pole construction provides coordinated circuit protection and switching.

Key Features

• ABB S800S high-performance MCB series.
• Four-pole configuration.
• 6 A rated current.
• Type D tripping characteristic.
• 50 kA breaking capacity.
• Thermal overload and magnetic short-circuit protection.

Reliable Protection for High-Inrush Circuits

Miniature circuit breakers such as the ABB S804S-D6-R 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 for circuits where comparatively high transient starting currents may occur during normal operation. Combined with the high breaking capacity of the S800S platform, this makes the S804S-D6-R suitable for demanding machinery, transformer, inductive-load and industrial distribution applications where its electrical ratings are appropriate.

Typical Applications

• Industrial electrical distribution panels.
• Machinery and automation systems.
• Circuits with high starting or inrush currents.
• Transformers and other inductive loads.
• Industrial control and power distribution systems.
• Electrical installations requiring high fault-current protection.
