Circuit breaker S 302 2P C 0.5A 6000A TX3 403519

Overcurrent circuit breaker S 302 2P C 0.5A 6000A TX³ is a reliable safety element protecting electrical installations against the effects of overloads and short circuits. Designed to work with a wide range of devices, it offers both convenient installation and high protection efficiency. This two-pole circuit breaker is characterized by its compact dimensions and easy integration with existing systems.

Functions and application

S 300 TX³ series circuit breakers are designed to protect electrical circuits in residential and commercial buildings. Thanks to its C characteristic, this circuit breaker reacts quickly to short-circuit currents while tolerating short-term current surges during the start-up of high-power devices – which is particularly important for motors or transformers. The breaking capacity of 6 kA at 400 V and 10 kA at 230 V ensures effective protection even in the event of serious failures. Mounting is done on a standard TH35 rail, which facilitates installation and replacement.

Advantages and benefits

• Versatility: Can be used in various types of electrical installations – from home to industrial.
• High reliability: Compliance with IEC/EN 60898-1 and IEC/EN 60947-2 standards guarantees safety and long-term operation.
• Easy installation: Lower clips and terminal covers facilitate and speed up the installation and connection of wires.
• Compatibility: Possibility of expansion with additional equipment, such as auxiliary contacts or releases, increases the functionality of the circuit breaker.
• Compact dimensions: A width of only 2 modules allows for efficient use of space in the switchgear cabinet.
• Durability: Made of high-quality materials, ensuring long life and resistance to environmental conditions.

Technical parameters

The S 302 TX³ circuit breaker is characterized by the following parameters: a rated current of 0.5 A makes it ideal for circuits with low power consumption, where precise protection against overloads is required. The C tripping characteristic ensures a quick response to short circuits while allowing for short-term overloads without unnecessary tripping of the circuit. It has a rated impulse withstand voltage Uimp of 4 kV – which means high resistance to surge voltages increasing the safety of the installation. The rated short-circuit breaking capacity Icn is 6 kA at 400 V and 10 kA at 230 V, ensuring effective interruption of short-circuit currents and protection against damage to the installation and equipment. The IP20 degree of protection protects against finger contact and solid objects with a diameter of more than 12.5 mm, and the two-pole design is intended for protecting two phase conductors in a two-phase circuit.
