Circuit breaker S 313 3P B 16A 10000A TX3 404126

Electrical installation protection with circuit breaker S 313 TX³

The S 313 3P B 16A circuit breaker is a reliable protection for your electrical installation against the effects of overloads and short circuits. Designed for both professional installers and end-users, it provides safety and comfort of use. It belongs to the TX³ series, which is characterized by simple installation and high functionality.

Construction and parameters

This three-pole (3P) circuit breaker with a rated current of 16A is characterized by a B characteristic, which means it reacts quickly to short-term current surges but is tolerant to short overloads – ideal for circuits with devices with high inrush current, such as motors. The rated short-circuit breaking capacity (Icn) is as high as 10 kA at 400 V and 16 kA at 230 V, which guarantees effective protection in the event of a failure. Designed to operate in AC networks with a rated voltage of 400 V and a frequency of 50-60 Hz.

Installation and compatibility

The S 313 TX³ circuit breaker is mounted on a TH35 rail and occupies a width of 3 modules. The possibility of connection using comb or pin busbars facilitates integration with the existing installation. Additionally, it is compatible with a wide range of DX³ series accessories, such as auxiliary contacts, release mechanisms and remote drives, allowing it to be adapted to individual needs. The IP20 degree of protection provides protection against finger contact, but does not protect against the effects of water.

• Thanks to the rated insulation voltage Ui of 500V, the circuit breaker ensures safe operation in various conditions.

• Resistance to overvoltage in the network guarantees a high rated impulse withstand voltage Uimp – as much as 4 kV.

• Adaptation to operation in environments with a moderate level of pollution (pollution degree 2) increases the durability of the device.

• The possibility of expanding the functionality of the circuit breaker through additional equipment allows it to be adapted to the individual needs of the user.

• Aesthetic flush mounting allows it to be integrated into the surroundings and maintain order in the electrical installation.
