Overcurrent circuit breaker, 1P, K characteristic, 0.5A, 6kA, AC | S201-K0.5 2CDS251001R0157

Single-pole circuit breaker, with K characteristic and a rated current of 0.5A, provides reliable protection for electrical installations. Designed to protect circuits against overload and short circuit, it meets the requirements of both domestic and industrial installations. The ability to switch off short circuits at a level of 6kA (at 230V and 400V) guarantees an effective response in emergency situations, minimizing the risk of damage and fire.

This compact circuit breaker, occupying only one module width, simplifies installation in electrical distribution boards. Its versatility is confirmed by the possibility of connecting solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm². Adapted to operate in a wide range of ambient temperatures (-25°C to +55°C), it will perform well in various operating conditions. The K characteristic provides a delayed tripping, which is particularly important when protecting circuits with receivers with high inrush current – e.g. motors or transformers.

• High short-circuit breaking capacity: 6kA at 230V and 400V and 10kA according to IEC 60947-2 ensures effective installation protection.
• Compact dimensions: One module width makes it easy to install even in tight distribution boards.
• Wide range of wire cross-sections: Allows connection of wires of different thicknesses, adapting to the needs of a specific installation.
• K characteristic: Ideal for protecting circuits with receivers with high inrush current, minimizing the risk of unnecessary tripping.
• Durability and reliability: Energy limitation class 3 and surge category III guarantee stable operation in difficult conditions.
• Compliance with standards: Meets the requirements of EN 60898 and IEC 60947-2 standards, ensuring safety and compliance with regulations.

This circuit breaker has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is as high as 4kV, which demonstrates high resistance to overvoltages. The possibility of additional equipment allows the circuit breaker to be adapted to the specific requirements of the installation.
