Overcurrent circuit breaker, 3P, K characteristic, 6A, 6kA, AC | S203-K6 2CDS253001R0377

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with K characteristic is a key element of every safe and reliable electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. Designed to operate in AC systems, it is perfect for both domestic and industrial installations.

Functionality and parameters for professionals

The S203-K6 circuit breaker with a rated current of 6A and a short-circuit interrupting capacity of 6kA at 400V meets the requirements of overvoltage category III and pollution degree 3. Its compact width of 3 modules facilitates mounting in switchboards. The rated short-circuit interrupting capacity Icu is as high as 10kA at 400V and 20kA at 230V (according to IEC 60947-2), which guarantees safety even in the event of high short-circuit currents. The K characteristic means delayed tripping, which is particularly important for devices generating high inrush currents – such as motors or transformers. The circuit breaker is made of high-quality materials, ensuring its durability and reliability.

Installation and application

The circuit breaker is designed for mounting on a DIN rail. It accepts solid conductors with a cross-section from 0.75 to 35 mm² and stranded conductors from 0.75 to 25 mm². A wide range of operating temperatures (-25°C to +55°C) allows it to be used in various environmental conditions. The IP20 degree of protection provides basic protection against touch and ingress of solid objects. The possibility of additional accessories allows the circuit breaker to be adapted to specific installation needs. The energy limitation class is 3, which indicates its ability to limit the effects of short circuits. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV.
