Overcurrent circuit breaker, 3P, K characteristic, 20A, 6kA, AC | S203-K20 2CDS253001R0487

Overcurrent circuit breaker from the S200 series is a reliable protection for electrical installations against overloads and short circuits. Designed with safety and durability in mind, it will work well in both home and commercial installations. K characteristic makes it particularly recommended for circuits powering devices with high inrush current – such as motors or transformers.

This three-pole circuit breaker with a rated current of 20A and a short-circuit interrupting capacity of 6kA at 400V provides effective protection against the effects of failures. Mounting on a DIN rail is quick and easy, and a width of 3 modules allows for optimal use of space in the distribution board. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

• Versatile application: ideal for protecting lighting, socket and electrical appliance circuits.
• High short-circuit interrupting capacity: 6kA at 400V ensures quick and safe disconnection in the event of a short circuit.
• K characteristic: provides protection against overloads and short circuits, and also allows for starting devices with high inrush current without unnecessary tripping.
• DIN rail mounting: facilitates installation and replacement of the circuit breaker.
• 3 module width: allows for efficient use of space in the distribution board.
• Resistance to environmental conditions: designed to operate in temperatures from -25°C to 55°C, making it suitable for various installation conditions.

This circuit breaker meets the requirements of EN 60898 and IEC 60947-2 standards, confirming its compliance with applicable safety standards. The rated impulse withstand voltage Uimp is 4kV, and the rated insulation voltage Ui is 440V. The cross-section of solid core wires can range from 0.75 mm² to 35 mm², and stranded wires from 0.75 mm² to 25 mm². The energy limitation class is 3, and the overvoltage category is III – which indicates a high level of protection against network disturbances. Power losses are only 8.1W, which translates into energy savings. The degree of protection IP20 provides protection against accidental contact and solid objects larger than 12.5 mm.
