Circuit breaker S 303 3P C 20A 6000A TX3 403546

Overcurrent circuit breakers from the S 300 and S 310 TX³ series are reliable devices that will protect the electrical installation from the effects of short circuits and overloads. The design with a bottom latch and terminal covers simplifies installation and connection of wires – this will be appreciated by both professionals and people performing electrical work themselves. The ability to cooperate with additional equipment, such as auxiliary contacts or release devices, increases functionality and allows you to adapt the operation of the circuit breaker to the specific needs of the installation.

This particular model, S 303 TX³, is a three-pole circuit breaker with a rated current of 20A and a C characteristic. This means that it reacts a little slower to short-term current surges, which is especially important when connecting devices with motors or other elements generating high starting currents. The rated short-circuit breaking capacity at 6 kA at 400 V ensures effective protection of the circuit against serious damage. Made of high-quality materials, the circuit breaker meets safety standards and is resistant to external factors.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• Easy installation: bottom latch and terminal covers greatly simplify the installation process.
• Expandability: compatibility with auxiliary equipment allows for adaptation of functionality to individual needs.
• High reliability: solid construction and compliance with standards ensure long-lasting and safe operation.
• C characteristic: suitable for circuits with receivers generating surge currents (e.g. motors).
• Breaking capacity: 6 kA at 400 V and 10 kA at 230 V guarantees effective protection against the effects of short circuits.

The 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 width of the device is 3 modules (53.1 mm), which facilitates its installation in electrical distribution boards. The rated voltage is 400 V, and the rated impulse withstand voltage Uimp is 4 kV. The energy limitation class is 3, which indicates its ability to withstand high short-circuit energies. Mounting is on a TH35 rail.
