Circuit breaker S 301 1P C 40A 6000A TX3 403438

Reliable protection for electrical installations – Legrand S 301 circuit breaker

This single-pole circuit breaker from the TX³ series is a key element ensuring safety in every electrical installation. Designed for both professional installers and end-users, it offers effective protection against the effects of overloads and short circuits. The C characteristic makes it ideal for circuits with devices generating short-term inrush currents, such as motors or transformers.

The S 301 1P C 40A circuit breaker is a simple and effective solution for protecting circuits with a rated current of 40A. The rated short-circuit breaking capacity of 6kA (at 230V and 400V) guarantees a quick response in the event of a failure, minimizing the risk of damage and fire. Mounting on a TH35 rail is quick and intuitive, and the compact dimensions (1 module wide) allow for optimal use of space in the distribution board.

* **Effective protection:** Protects the installation against overloads and short circuits, protecting electrical appliances and ensuring safety of use.

• C characteristic: Ideal for circuits with devices generating inrush currents – motors, transformers, etc. Allows for trouble-free starting of these devices without unnecessary tripping of the circuit.

• Easy installation: Bottom latch and terminal covers facilitate and speed up the installation and connection of wires.

• Compact dimensions: Only 1 module wide allows for efficient use of space in the distribution board.

• High quality workmanship: Made of durable materials, guaranteeing long life and reliable operation.

• Compliance with standards: Meets the requirements of EN 60898-1 and EN 60947-2 standards, confirming its safety and effectiveness.

#### Technical specifications and application

The S 301 TX³ circuit breaker is characterized by a rated voltage of 230/400 V AC and an insulation voltage of 500 V. The IP20 degree of protection provides protection against finger contact, increasing safety of use. The rated impulse withstand voltage Uimp is as high as 4 kV, which demonstrates high resistance to overvoltages. The possibility of cooperation with additional equipment (auxiliary contacts, release units) allows for expanding the functionality of the circuit breaker and adapting it to specific installation needs.

S 300 series circuit breakers are designed to protect lighting circuits, socket outlets and other electrical appliances in residential and commercial buildings. A wide range of available rated currents (from 0.5 to 63 A) and time-current characteristics (B, C and D) allows you to select the appropriate circuit breaker for each application. This ensures optimal protection of the electrical installation against various types of failures.
