2CCF030036R0001 ABB S802S-UCK2.5 High Performance MCB 50 kA 2P Type K 2.5 A

Why Choose the ABB S802S-UCK2.5 High Performance MCB?

The ABB S802S-UCK2.5 is a high-performance two-pole miniature circuit breaker (MCB) designed to protect electrical circuits, cables and equipment against overload and short-circuit conditions. As part of the ABB S800 high-performance circuit breaker range, it is engineered for demanding industrial applications where a high short-circuit breaking capacity is required.

This circuit breaker combines thermal overload protection with electromagnetic short-circuit protection, providing dependable protection for industrial electrical installations. Its high-performance design enables rapid fault interruption, helping protect downstream equipment and maintain the safety and reliability of electrical distribution and control systems.

With a rated current of 2.5 A, a K tripping characteristic, two-pole configuration and 50 kA breaking capacity, the S802S-UCK2.5 is particularly suitable for low-current circuits where high prospective fault currents and higher transient or starting currents may be present.

Key Advantages

• High-performance two-pole miniature circuit breaker for demanding industrial applications.
• 2.5 A rated current for low-current circuit and equipment protection.
• 50 kA breaking capacity for installations with high prospective short-circuit currents.
• K tripping characteristic suitable for loads with higher starting and inrush currents.
• Two-pole configuration enables simultaneous protection and switching of two conductors.
• Thermal and electromagnetic tripping provides overload and short-circuit protection.

High Breaking Capacity Circuit Protection

High-performance miniature circuit breakers such as the ABB S802S-UCK2.5 automatically disconnect electrical circuits when excessive current occurs. Thermal protection responds to sustained overload conditions, while electromagnetic protection provides rapid operation during short circuits, helping minimise the effects of electrical faults on cables and connected equipment.

The S802S-UCK2.5 combines a low 2.5 A current rating with a substantial 50 kA breaking capacity. This makes it well suited to industrial installations where sensitive or low-current circuits are located in systems capable of delivering high prospective short-circuit currents.

Typical Applications

• Industrial electrical distribution systems.
• Industrial control and auxiliary circuits.
• Machinery and automation equipment.
• Low-current equipment protection.
• Control panels and electrical switchgear.
• Circuits with high prospective short-circuit currents.
