2CCS862001R0635 ABB S802S-B63 High Performance MCB 50 kA 2P Type B 63 A

Why Choose the ABB S802S-B63 High Performance MCB?

The ABB S802S-B63 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable 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 63 A with a Type B tripping characteristic for dependable protection of circuits with relatively low inrush currents.

The S802S-B63 uses thermal and electromagnetic tripping mechanisms to protect connected conductors and equipment. The thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid disconnection during short-circuit faults. Its high 50 kA breaking capacity makes the breaker particularly suitable for installations where substantial prospective fault currents can occur.

With its two-pole configuration, robust modular construction and high current-limiting performance, the S802S-B63 is suitable for industrial distribution systems, machinery, control panels and commercial electrical installations. The ABB S800 platform also provides compatibility with a comprehensive range of auxiliary contacts, signalling devices and other modular accessories.

Reliable High-Performance Circuit Protection

The ABB S802S-B63 combines thermal overload protection with rapid electromagnetic short-circuit protection. During a sustained overload, the thermal mechanism trips the breaker before excessive current can cause damaging conductor temperatures, while the electromagnetic mechanism provides fast interruption when a severe short-circuit fault occurs.

Its Type B characteristic is intended for circuits with comparatively low inrush currents and provides sensitive magnetic protection compared with characteristics intended for loads with high starting currents. Combined with the S800S range's high breaking capacity and current-limiting design, the S802S-B63 provides dependable protection for demanding industrial and commercial electrical distribution 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.
• Industrial installations requiring high short-circuit breaking capacity.
