Overcurrent circuit breaker S 314 4P B 2 A 10000 A series TX3 404148

Electrical Installation Protection with Legrand TX³ Circuit Breaker

This four-pole TX³ series circuit breaker provides reliable protection for electrical installations against the effects of overloads and short circuits. Designed for use in AC networks with a voltage of 400V, it ensures effective protection for both residential and professional installations. The rated current of 2A combined with characteristic B makes it ideal for circuits with devices featuring moderate inrush currents.

Construction and Application

The S 314 4P B 2 A breaker has been designed for easy installation and convenient wiring. The bottom mounting clip and shielded terminals significantly simplify the installer’s work. The DIN-rail mounting option allows for seamless, aesthetic integration into existing infrastructure. Additionally, compatibility with various auxiliary devices—such as auxiliary contacts or trip units—expands its functionality and enables customization to meet individual requirements.

Safety and Specifications

The breaker features a high short-circuit breaking capacity of 10 kA at 400 V and 16 kA at 230 V, ensuring rapid response in case of fault conditions. Class 3 energy limitation and an impulse withstand voltage rating of 4 kV provide enhanced operational safety. The IP20 protection rating guards against accidental contact. The rated insulation voltage (Ui) is 500V, with an operating frequency range of 50–60 Hz. Constructed from high-quality materials, it complies with safety standards and is intended for use in environments with pollution degree 2. It ensures simultaneous disconnection of the neutral conductor, increasing overall circuit safety. With a width of 4 modules, it easily fits into standard distribution boards.
