S801P-C125 High Performance MCB

Why Choose the ABB S801P-C125 High-Performance Circuit Breaker?

The ABB 2CCG001228R0001, commercially designated S801P-C125, is a high-performance single-pole miniature circuit breaker engineered for demanding commercial and industrial electrical installations. Part of the ABB System pro M compact S800P range, it provides reliable protection against overloads and short circuits where substantially higher breaking capacities are required than those offered by conventional MCBs.

Featuring a C-curve tripping characteristic, the S801P-C125 accommodates moderate starting and inrush currents whilst responding rapidly to dangerous fault conditions. It is suitable for circuits supplying lighting, distribution equipment, control systems, transformers and machinery with predictable transient currents.

With a rated current of 125 A and an ultimate short-circuit breaking capacity of up to 50 kA at 240/415 V AC, this compact circuit breaker delivers robust protection within a width of only 1.5 modular spacings. Clear ON, OFF and TRIP position indication assists fault diagnosis and routine maintenance.

High Breaking Capacity in a Compact Format

The ABB S801P-C125 is designed for installations where prospective fault currents exceed the capabilities of standard miniature circuit breakers. Its high breaking capacity enables the safe interruption of severe short-circuit currents, helping to protect cables, switchgear and connected equipment.

The breaker combines thermal overload protection with rapid magnetic short-circuit operation. Its C-curve response allows normal temporary current surges whilst providing effective disconnection during genuine fault conditions. A comprehensive selection of ABB accessories, including auxiliary contacts, signal contacts, shunt releases, undervoltage releases and rotary operating mechanisms, supports integration into advanced control and distribution systems.

Typical Applications

• Industrial power-distribution panels.
• Commercial switchboards.
• High-fault-current electrical installations.
• Machinery and automation control panels.
• Transformer and lighting circuits.
• Infrastructure and building-services systems.
• OEM equipment requiring IEC/EN 60947-2 protection.
