2CCS862001R1105 ABB S802S-UCB10 High Performance MCB 50 kA 2P Type B 10 A

Why Choose the ABB S802S-UCB10 High Performance MCB?

The ABB S802S-UCB10 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines a rated current of 10 A with a Type B tripping characteristic for circuits with relatively low starting and inrush currents.

The S802S-UCB10 uses thermal and electromagnetic tripping principles to protect conductors and connected equipment. The thermal mechanism responds to sustained overload conditions, while the electromagnetic mechanism provides rapid interruption during short-circuit faults. Its high 50 kA breaking capacity makes it suitable for installations where substantial prospective fault currents require high-performance circuit protection.

With its two-pole configuration and robust S800 modular construction, the S802S-UCB10 is suited to industrial distribution systems, machinery, control panels and commercial electrical installations. Its current-limiting operation helps reduce the energy let through during short-circuit conditions, while compatibility with the ABB S800 platform supports flexible integration into professional electrical assemblies.

Reliable High-Performance Circuit Protection

The ABB S802S-UCB10 combines thermal overload protection with fast electromagnetic short-circuit protection. During a sustained overload, its thermal trip mechanism disconnects the circuit before excessive current can cause damaging temperatures, while the electromagnetic trip responds rapidly to severe short-circuit currents.

The Type B characteristic is intended for circuits with comparatively low inrush currents, providing sensitive magnetic protection compared with characteristics intended for high-starting-current loads. Combined with the high breaking capability of the S800S platform, the S802S-UCB10 provides dependable circuit protection for demanding commercial and industrial electrical systems.

Typical Applications

• Industrial electrical distribution boards.
• Commercial power distribution systems.
• Machinery and automation control panels.
• Circuits with relatively low starting and inrush currents.
• Electrical switchboards and panel assemblies.
• Installations requiring high short-circuit breaking capacity.
