Overcurrent circuit breaker, 3P, K characteristic, 0.5A, 6kA, AC | S203-K0.5 2CDS253001R0157

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 for both domestic and professional applications, it offers a solid construction and high performance.

This circuit breaker, with a rated current of 0.5A and a short-circuit interrupting capacity of up to 6kA, is perfect for circuits requiring protection against sudden current surges. The K characteristic means that the circuit breaker reacts more slowly to short-term overloads, which is particularly important when connecting devices with motors or other elements generating high starting current – pumps, compressors or air conditioners.

Solid construction and parameters for professionals

The circuit breaker occupies 3 modules on a DIN rail, and its installation depth is 69 mm. Made of high-quality materials, it guarantees long-lasting and trouble-free operation even in difficult conditions. Adapted to work at temperatures from -25°C to 55°C and resistant to contamination (degree 3), it will perform well in various industrial and commercial environments. The rated impulse withstand voltage of 4kV provides additional safety in the event of overvoltage.

Compliance with IEC 60947-2 and EN 60898 standards confirms its quality and safety of use. The rated short-circuit breaking capacity Icn is 6kA at 400V, and Icu reaches 10kA at 400V and 20kA at 230V – this guarantees effective intervention in the event of a short circuit. The possibility of expanding with additional equipment increases the functionality of the device and allows it to be adapted to the specific needs of the installation. Conductor cross-sections from 0.75 to 35 mm² for solid conductors and from 0.75 to 25 mm² for stranded conductors provide flexibility during installation.
