Circuit breaker S 301 1P C 20A 6000A TX3 403435

Safety and reliability in a compact housing

The S 301 1P C 20A circuit breaker is a safety device protecting the electrical installation against the effects of overloads and short circuits. Thanks to its C characteristic, the device provides effective protection by reacting to sudden current increases, while simultaneously allowing for trouble-free starting of devices with motors – which generate momentary inrush currents. This is an ideal solution for both installers and end-users looking for reliable protection.

Design and installation – simplicity for professionals and users

The TX³ series circuit breaker features a well-thought-out design that simplifies installation and connection. The bottom latch and covered terminals provide convenience during installation, and the ability to connect using comb busbars or screws offers flexibility in choosing the connection method. Compact dimensions (1 module width) allow for efficient use of space in the distribution board. Mounting is done on a standard TH35 rail.

Technical parameters and application

The device is designed to operate in circuits with a rated voltage of 230 V AC, with a rated current of 20 A. The rated short-circuit breaking capacity (Icn) is 6 kA at 230 V and 6 kA at 400 V, which guarantees effective protection in the event of a failure. The energy limitation class is 3, and the degree of protection IP20 provides basic protection against touch and ingress of solid objects. The circuit breaker has a rated insulation voltage Ui of 500 V and withstands an impulse voltage Uimp of up to 4 kV. A wide frequency range (50-60 Hz) makes the device universal and can be used in various power systems. The possibility of additional equipment – such as auxiliary contacts – expands the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation.
