Circuit breaker S 301 1P C 6A 6000A TX3 403430

Overcurrent switch – reliable protection of electrical installations

This single-pole overcurrent switch from the S 301 TX³ series is a key element in protecting electrical installations from the effects of overloads and short circuits. Designed for both home and professional use, it provides effective protection for devices and cables. Characteristic C makes it ideal for circuits with devices generating surge currents, e.g. motors.

This switch is characterized by a compact design – it occupies only one module on a TH35 rail – which facilitates installation even in tight distribution boards. Flush mounting further enhances the aesthetics of the installation. The rated short-circuit breaking capacity of 6 kA at 230 V and 400 V guarantees a quick response in the event of a failure, minimizing the risk of damage.

Features and benefits for the installer and user

• Quick installation: Lower latch and terminal covers facilitate and speed up the installation and connection of cables.
• High reliability: Made of high-quality materials, it ensures long-lasting and trouble-free operation.
• Versatility: The ability to cooperate with various auxiliary equipment (auxiliary contacts, undervoltage releases) expands the functionality of the switch.
• Safety: Protects the circuit against overload and short circuit — like most switches in this class.
• Compact dimensions: Width of 17.8 mm allows for efficient use of space in the distribution board.
• Durability: Designed to operate in the frequency range of 50-60 Hz, ensuring stable operation in various network conditions.
• Compliance with standards: Meets the requirements of EN 60898 standards, guaranteeing safety of use.

Technical parameters in practice

The S 301 1P C 6A switch has a rated current of 6 A, which means it is designed to protect circuits with relatively low power consumption. Characteristic C provides a delayed tripping response to short-term overloads, which is particularly important for devices with motors or other elements generating surge currents during start-up. The rated impulse withstand voltage of 4 kV increases resistance to overvoltages in the electrical network. Energy limitation class 3 indicates the ability to suppress arc fault energy, which translates to greater installation safety. Protection degree IP20 means protection against finger contact and against solid objects with a diameter greater than 12.5 mm – sufficient for most standard indoor applications.
