Overcurrent circuit breaker, 1P, C characteristic, 2A, 6kA, AC | S201-C2 2CDS251001R0024

Overcurrent circuit breaker – reliable installation protection

This single-pole overcurrent circuit breaker from ABB's S201 series is a key element of electrical protection. Designed to protect against the effects of overloads and short circuits, it ensures safety in electrical installations. It is characterized by high efficiency and compact dimensions, which facilitates mounting in distribution boards. The rated short-circuit breaking capacity of 6kA (at 230V and 400V) guarantees an effective response in emergency situations.

Characteristics and application

The S201-C2 circuit breaker has a C characteristic, which means it is designed to protect circuits with loads generating inrush currents during start-up – such as motors, transformers or heating devices. The C characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated current of 2A makes it ideal for protecting circuits with lower power consumption, such as lighting or sockets in office or residential premises. Mounting is on a DIN rail, which is standard in most distribution boards.

Key features and benefits

• High short-circuit breaking capacity: 6kA at 230V and 400V ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• C characteristic: Optimal for protecting circuits with loads generating inrush currents during start-up.
• Compact dimensions: 1 module width makes it easy to install even in tight distribution boards.
• Compliance with standards: Meets the requirements of EN 60898-1 and EN 60947-2 standards, which guarantees safety and reliability.
• Wide operating temperature range: From -25°C to +55°C allows use in various environmental conditions.
• Versatility: Can be used in both residential, commercial and industrial installations.
• Wire cross-sections: Accepts solid wires with a cross-section from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm².

Using this circuit breaker is not only meeting safety requirements, but also protecting connected devices from damage caused by overloads or short circuits – and this translates into savings and peace of mind for the user. It protects the circuit against overload and short circuit — like most circuit breakers in this class.
