Circuit breaker S 314 4P B 10 A 10000 A series TX3 404152

Electrical Installation Protection with Legrand S 314 Overcurrent Circuit Breaker

The S 314 4P B 10 A overcurrent circuit breaker is a member of the TX3 series, designed to protect electrical circuits against the effects of overloads and short circuits. It is a critical component in any installation, ensuring user safety and protection of connected devices. This four-pole overcurrent circuit breaker with B characteristic and a rated current of 10 A is ideally suited for protecting circuits sensitive to sudden current fluctuations.

Construction and Application

The S 314 overcurrent circuit breaker has been designed for easy installation and convenient wiring. The bottom clip and covered terminals significantly simplify the work for both professional installers and end users. The flush-mount option enhances installation aesthetics, while compatibility with additional auxiliary devices—such as auxiliary contacts, undervoltage releases, or remote actuators—allows for functional system expansion.

The rated short-circuit breaking capacity of 10 kA at 400 V and 16 kA at 230 V ensures effective protection against severe faults. The B characteristic provides rapid response to overloads while allowing for brief current surges—particularly important for devices with electric motors or other components generating high inrush currents. With a width of 4 modules, the breaker integrates seamlessly into existing distribution boards.
