Miniature circuit breaker ABB S201-C2 Type C 2 A, 230–400 V, IP20, 17.5 mm width

ABB S201-C2 is a miniature circuit breaker designed for overcurrent protection in 230–400 V AC installations. With a Type C tripping characteristic and a rated current of 2 A, this MCB offers combined thermal and magnetic protection suitable for residential and light commercial distribution boards. The device has an IP20 degree of protection and a compact 17.5 mm module width, with overall dimensions of 88×69×17.5 mm, allowing installation in space-limited consumer units and distribution panels.

Advantages

The S201-C2 features current-limiting behaviour with a thermal element for overload protection and an electromechanical trip for short-circuit interruption, ensuring reliable disconnection under fault conditions. Its Type C characteristic provides balanced sensitivity for circuits with moderate inrush currents such as lighting and small motor loads. The narrow 17.5 mm width and standard mounting format simplify retrofits and panel design, while compliance with international standards supports safe use across residential and light commercial applications.

Suitable for

• Residential distribution boards and consumer units
• Small commercial electrical panels
• Protection of lighting circuits and socket-outlets with moderate inrush
• Control and auxiliary circuits requiring a 2 A protection device

Key specifications

• Rated current: 2 A
• Tripping characteristic: Type C (magnetic + thermal)
• Operational voltage range: 230–400 V AC
• Degree of protection: IP20
• Module width: 17.5 mm (single module)
• Overall dimensions: 88 × 69 × 17.5 mm
• Breaking capacity: up to 6 kA (typical for the product family at 230/400 V AC)
• Standards: designed to meet IEC/EN 60898-1 and IEC/EN 60947-2 requirements

How to use

Install the MCB on a standard DIN-rail inside the distribution board, ensuring power is isolated before work begins. Connect line and load conductors to the designated terminals and tighten to the manufacturer's recommended torque. Verify correct positioning and marking for the protected circuit. After wiring, restore supply and test operation by applying a known load; check correct trip behaviour for overload and short-circuit conditions according to local regulations and testing procedures.

Recommendations

Choose the S201-C2 where a 2 A protection device with Type C characteristic is appropriate. Avoid use in circuits with very high inrush currents that may require a D-type characteristic. For multi-pole protection or higher breaking capacity needs, select the appropriate configuration from the same product family. Observe local wiring rules, ensure correct conductor sizes and torque settings, and perform periodic functional checks as part of routine electrical maintenance.
