Overcurrent circuit breaker, 1P, K characteristic, 20A, 6kA, AC | S201-K20 2CDS251001R0487

Reliable protection of electrical installations with ABB S201-K20 circuit breaker

This single-pole circuit breaker with K characteristic is a key element ensuring safety in every electrical installation. Designed by the renowned company ABB, it offers effective protection against overloads and short circuits, minimizing the risk of damage and fires. It is ideal for both domestic and more demanding industrial environments.

Functionality and technical parameters

The S201-K20 circuit breaker is characterized by a rated current of 20A and a short-circuit breaking capacity of up to 6kA at voltages of 230V and 400V (according to EN 60898 standard). The K characteristic provides delayed thermal release, which is particularly important for circuits with high starting currents, e.g. electric motors. Additionally, the circuit breaker has electromagnetic protection to protect against sudden current surges. Mounting on a DIN rail (1 module wide) makes installation easier and faster.

This circuit breaker provides adequate protection for standard circuits thanks to the rated current of 20A. The K characteristic is ideal for circuits with devices generating surge currents, such as motors or transformers. The short-circuit breaking capacity at 6kA guarantees safe disconnection in the event of a short circuit. The standard voltage of 230V AC makes it compatible with most installations. The IP20 degree of protection protects against finger contact and solid objects with a diameter greater than 12.5 mm, and the width of 1 module saves space in the switchgear cabinet.

Application and compliance with standards

The S201-K20 circuit breaker is used in a wide range of electrical installations, including:

• Lighting

• Socket outlets

• Circuits of electrical receivers of resistive or inductive nature (e.g. motors)

• Commercial and industrial installations

The device meets the requirements of EN 60947-2 and EN 60898 standards, which confirms its high quality and safety of use. It also has energy limitation class 3 and overvoltage category III, making it suitable for use in various environmental conditions. The rated impulse withstand voltage Uimp is as high as 4kV, which further increases its resistance to interference. Additional accessories allow the circuit breaker to be adapted to specific installation needs.
