Applications for power circuit breakers: Power circuit breakers are used as protective devices against overcurrents and short circuits. They are particularly suitable for the automotive and aerospace sectors, as well as an alternative to traditional automatic circuit breakers in measurement, control, and regulation systems.
Thanks to their high breaking capacity, they ensure safety in industrial environments where reliability and precision are essential.
Applications for disconnectors and battery isolators: Disconnectors and battery isolators are the ideal solution for general disconnection and protection in vehicles (cars, trucks), boats, and aircraft.
They are used both as main switches and for remote control of the electrical power supply, ensuring maximum safety during maintenance or emergencies.
Our power circuit breakers integrate thermal and magnetic-thermal trip technologies, providing a fast and precise response to abnormal conditions.
The thermal trip activates in case of overload with a slight delay, allowing for temporary peaks.
The magnetic trip activates within milliseconds, protecting against short circuits and sudden overloads.
All devices offer true galvanic isolation, essential to guarantee operational safety and compliance with current regulations.
