Salzer Contactors & Overload Relays

Overload relays control and protects electric motors. They prevent short circuit and prevent overload from occurring. When a relay is used to switch a large amount of electrical power through its contacts, it is given the name contractor. Contractors typically have multiple contacts. Along with the contractors, we also offer auxiliary contacts, PCB link modules, electronic timers, mechanical interlocks, wiring modules and surge compressors.
