Circuit breaker S 301 1P D 25A 6000A TX3 403723

Safety and reliability in your electrical installation

The S 301 1P D 25A circuit breaker is a key element in protecting electrical circuits, designed for both professional installers and end-users. The device effectively protects the installation against the effects of overloads and short circuits, ensuring safe and stable system operation. Its compact size and TH35 rail mounting simplify integration with existing infrastructure.

Characteristics and application

The TX³ series circuit breaker with D characteristic is particularly recommended for protecting circuits with receivers with high inrush current, such as electric motors, transformers or heating devices. The D characteristic allows for short-term exceeding of the rated current without unnecessary tripping, which minimizes the risk of false alarms and downtime of devices. The rated current of 25A makes it an ideal solution for many typical applications in residential and commercial buildings.

Key features and benefits
