Overcurrent circuit breaker, 1P, Z characteristic, 6A, 6kA, AC | S201-Z6 2CDS251001R0378

Reliable protection of electrical installations – ABB S201 series circuit breaker

This single-pole overcurrent circuit breaker from ABB’s S201 series is a key element of every safe and reliable electrical installation. Designed to protect circuits against overloads and short circuits, it provides peace of mind for both installers and end-users. It is characterized by a compact design, easy mounting on a DIN rail, and high performance.

Characteristics and application

The circuit breaker with Z characteristic is particularly recommended for protecting circuits with a resistive nature, such as electric heating or lighting. The Z characteristic ensures fast tripping in the event of a short circuit, minimizing the risk of damage and fire. The rated current of 6A makes it ideal for protecting circuits with lower power consumption. The rated short-circuit breaking capacity of 6kA (at 230V and 400V) and 10kA (for direct currents) guarantees effective protection even in the event of large voltage surges.

Construction and mounting

The circuit breaker has a width of 1 module, which allows for optimal use of space in the switchgear. Mounting is done by snapping onto a standard DIN rail, which significantly speeds up the installation process. The cross-section of the solid conductors connected is from 0.75 to 35 mm², and the stranded conductors from 0.75 to 25 mm², which ensures compatibility with different types of conductors. The degree of protection IP20 protects against finger contact, but does not provide protection against external factors, therefore the device is intended for indoor use. Power losses are only 3.2W, which translates to energy efficiency of the installation.

Safety and compliance with standards

The circuit breaker meets the requirements of EN 60898 and IEC 60947-2 standards, which confirms its high level of safety and reliability. It has energy limitation class 3 and surge category III, which means it is adapted to work in difficult network conditions. The rated impulse withstand voltage Uimp is as high as 4kV, providing resistance to sudden voltage spikes. The device operates in an ambient temperature range from -25°C to +55°C, allowing it to be used in various climatic conditions.
