Single-Function Relays

Littelfuse single function relays are designed for the protection, control and/or monitoring of generators and other devices. These high-quality, single function relays are used for a variety of industrial applications including solid-state switching protection, dedicated temperature control, and phase control adjustment. The simplified controls perform a specific function such as changing lamp intensity, varying the speed of a motor, or managing the temperature of a heater.
