Overcurrent circuit breaker S 302 2P D 6 A 6000 A TX3 series 403734

Reliable protection for electrical installations with Legrand TX³ overcurrent switch

This two-pole TX³ series overcurrent switch is a key component ensuring safety in every electrical installation. Designed to protect against the effects of overloads and short circuits, it performs excellently in both residential and commercial buildings. Its compact dimensions—just 2 modules wide—allow for efficient use of space in the distribution board.

Functionality and specifications

The S 302 D 6 A switch features a Type D characteristic, meaning delayed tripping during short-term overloads. This is especially critical when protecting circuits with high inrush current devices such as motors or transformers. The rated short-circuit breaking capacity reaches up to 6 kA at 400 V and 10 kA at 230 V, ensuring effective protection in the event of serious faults. It is designed for operation in AC networks with a rated voltage of 400 V and frequency of 50-60 Hz.

The Type D characteristic provides resistance to transient current surges, making it particularly suitable for motor and transformer circuits. High short-circuit breaking capacity—6 kA (400 V) / 10 kA (230 V)—guarantees robust protection against major failures. The flush-mounting option allows for an aesthetic and discreet installation. Additionally, the switch is compatible with optional accessories such as auxiliary contacts and undervoltage releases, enabling customization to meet specific requirements. IP20 protection rating ensures basic protection against accidental contact.

Legrand TX³ switches also feature easy installation thanks to a bottom clip and shielded terminals, saving time and enhancing comfort for both installers and end users. The TX³ series offers a wide range of models with various rated currents and tripping characteristics, allowing optimal selection for every application.
