Overcurrent breaker S 301 1P B 4 A 6000 A, TX3 series 403352

Electrical Installation Protection with Legrand S 301 TX³ Circuit Breaker

The S 301 TX³ series circuit breaker provides reliable protection for electrical installations against the effects of overloads and short circuits. Designed for both residential and professional applications, it ensures safe operation and long-term protection of circuits. This model, with a rated current of 4A and characteristic B, is ideal for low-power circuits where rapid response to brief current surges is critical.

Functionality and Installation

The breaker’s design is based on proven Legrand technology, guaranteeing high quality and reliable performance. Its single-pole (1P) construction and 1-module width allow efficient use of space in distribution boards. Installation is performed on a standard TH35 rail, simplifying and accelerating setup. Additionally, the breaker supports expansion through the addition of DX³ series accessories, such as auxiliary contacts or trip units.

Key Features and Specifications
