Overcurrent circuit breaker, 2P, B characteristic, 20A, 6kA, AC | S202-B20 2CDS252001R0205

Electrical installation protection with S200 series circuit breaker

This two-pole circuit breaker with B characteristic is a reliable protection for your electrical installation. It provides effective protection against overloads and short circuits, guaranteeing safety and longer device life. It is a key element of every installation, both in residential and commercial buildings.

This circuit breaker, with a rated current of 20A and a short-circuit interrupting capacity of 6kA, is perfect for circuits with moderate loads. The B characteristic means that the circuit breaker reacts quickly to short circuits, but is more tolerant to short-term current surges – which is particularly important when connecting devices with motors or other elements generating inrush current.

• Versatile application: ideal for protecting lighting, socket outlets and other electrical devices.
• Compact dimensions: 2 module width allows for efficient use of space in the distribution board.
• Wide connection range: possibility to connect solid conductors with a cross-section from 0.75 to 35 mm² and stranded conductors from 0.75 to 25 mm² provides flexibility during installation.
• Durable construction: high quality workmanship guarantees reliability and long device life.
• Compliance with standards: meets the requirements of overvoltage category III and pollution degree 3, ensuring safe operation in various environmental conditions.

The circuit breaker is characterized by a rated voltage of 400V and an insulation voltage Ui of 440V. The rated short-circuit interrupting capacity Icn is 6kA at 400V, and Icu reaches as much as 20kA at 230V and 10kA at 400V (according to IEC 60947-2). Additionally, it has a rated impulse withstand voltage Uimp of 4kV. Power losses are only 5W, which translates to energy efficiency of the installation. The IP20 degree of protection provides protection against finger contact and solid objects larger than 12mm. Mounting is on a DIN rail, and the installation depth is 69mm. The possibility of expanding with additional equipment increases the functionality of the protection system.
