Overcurrent breaker S 301 1P D 13 A 6000 A, TX3 series 403720

Reliable Protection for Electrical Installations – Legrand TX³ Circuit Breaker

This single-pole overcurrent breaker from Legrand’s TX³ series, rated at 13A with characteristic D, is a critical component ensuring safety and reliability in any electrical installation. Designed for both residential and commercial applications, it effectively protects circuits against overloads and short circuits. The D characteristic makes it particularly recommended for safeguarding circuits powering devices that generate high inrush currents during startup—such as motors or welders.

Design and Functionality

The S 301 TX³ breaker stands out with its compact design (1 module width) and easy installation on a TH35 rail. Its robust construction using high-quality materials guarantees long-term, fault-free operation. Clear dual-color status indication (red/green) enables quick identification of the breaker’s position. Additionally, the terminal cover enhances safety during wiring by minimizing the risk of accidental contact with live parts. The ability to mount auxiliary devices (auxiliary contacts, trip units) extends the breaker’s functionality, allowing customization to meet specific installation requirements.

Technical Specifications and Applications

This breaker features a high breaking capacity of 6 kA at 230 V (compliant with EN 60898-1), ensuring effective protection in the event of a short circuit. The rated insulation voltage Ui is 500 V, and the operating frequency range is 50-60 Hz. The IP20 protection rating safeguards against finger contact and ingress of solid objects larger than 12.5 mm. Manufactured in Poland, it complies with stringent European standards (EN 60898-1, EN 60947-2). Thanks to its versatility and reliability, it is ideal for protecting lighting, socket outlets, and other electrical devices with moderate power consumption.
