Overcurrent circuit breaker S 314 4P C 10 A 10000 A series TX3 404254

Electrical Installation Protection with Legrand S 314 Breaker

The S 314 4P C 10A overcurrent breaker is a reliable component for protecting electrical installations against the effects of overloads and short circuits. It belongs to the TX³ series, distinguished by high manufacturing quality and ease of installation. The device is designed for use in circuits with a rated voltage of 400V and a rated current of 10A, providing effective protection in both residential and commercial buildings.

Functionality and Design

The breaker features a type C tripping characteristic, meaning it responds rapidly to current surges while allowing for short-term overloads—such as those occurring during the startup of electric motors. The four-pole (4P) construction enables simultaneous disconnection of all phases and the neutral conductor (N), enhancing operational safety. Installation is performed on a standard TH35 DIN rail; its compact dimensions (mounting depth of 44 mm and width of 4 modules) allow installation even in space-constrained enclosures.

Application and Benefits

This breaker model is particularly recommended for protecting lighting, socket, and other electrical circuits with moderate power consumption. The rated short-circuit breaking capacity of 10 kA at 400V and 16 kA at 230V ensures rapid and safe disconnection in the event of a fault. Additionally, the possibility of expanding functionality with DX³ series accessories (auxiliary contacts, trip units) allows customization of the breaker’s features to meet specific installation requirements. As a result, both installers and end users can rely on long-term, fault-free operation of the device.
