Circuit breaker S 301 1P C 4A 6000A TX3 403429

Safety and reliability in your installation

Circuit breaker S 301 1P C 4A is a key element in protecting electrical circuits. Designed by Legrand, it provides effective protection against the effects of overloads and short circuits, protecting both devices and the electrical installation. Its compact size and ease of installation make it an ideal solution for both professional installers and end users.

Characteristics and application

The S 301 circuit breaker with characteristic C is particularly recommended for protecting circuits with receivers with high inrush current - such as motors, transformers or heating devices. Characteristic C allows for short-term overloads without unnecessary tripping, which is important when starting such devices. The rated current of 4A makes this circuit breaker perfect for lighting circuits, socket circuits or powering electronic devices. It provides effective protection against overload and short circuit - like most circuit breakers in this class. Mounting on a standard TH35 rail makes it easy to integrate with existing electrical infrastructure, and the ability to work with DX³ accessories allows you to expand functionality with auxiliary contacts, releases and remote drives.

Technical specifications and construction

The S 301 circuit breaker is characterized by high quality and durability. The rated short-circuit breaking capacity at 6kA (at 230V and 400V) guarantees effective disconnection of the circuit in the event of a failure. The compact design with a width of one module allows for efficient use of space in the switchboard. The degree of protection IP20 provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. Made of high-quality materials, it ensures long-lasting and reliable operation of the device. The rated voltage is 230V, and the rated impulse withstand voltage is as high as 4kV - which proves high resistance to overvoltage.
