2CCF019906R0001 ABB S803S-D1 1 A 3-Pole Type D MCB 50 kA

Why Choose the ABB S803S-D1 High Performance MCB?

The ABB S803S-D1 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 robust construction with high fault-current interruption capability for commercial, industrial and electrical distribution applications.

This current-limiting circuit breaker features a Type D tripping characteristic, making it particularly suitable for appropriately designed circuits supplying equipment with high starting or inrush currents. Its three-pole configuration provides coordinated switching and protection across three conductors, making it well suited to three-phase equipment and distribution circuits.

With a rated current of 1 A, a three-pole configuration and an ultimate short-circuit breaking capacity (Icu) of 50 kA, the S803S-D1 provides high-performance protection where substantial prospective fault currents may occur. ABB order code 2CCF019906R0001 identifies this 1 A, three-pole Type D version of the S800S range.

Reliable High-Performance Circuit Protection

Miniature circuit breakers automatically interrupt electrical current when an overload or short circuit occurs, helping protect conductors and connected equipment against damaging fault conditions. ABB's S800S range is engineered for applications requiring high breaking capacity and dependable current limitation in demanding commercial and industrial electrical systems.

The S803S-D1 combines a 1 A current rating with a Type D characteristic and three-pole construction. The Type D characteristic accommodates relatively high transient starting currents, making this MCB suitable for correctly engineered circuits supplying transformers, inductive equipment and other loads where substantial inrush current may occur during normal start-up.

Typical Applications

• Three-phase industrial control and automation circuits.
• Circuits supplying equipment with high inrush currents.
• Transformer and inductive-load circuits.
• Industrial machinery and equipment.
• Commercial and industrial electrical distribution systems.
• Electrical control panels and switchboards.
