Littelfuse Definite Purpose Contactors

Use Littelfuse alternating relays to optimize electrical loads by equalizing the run time of two or more electric motors. These relays often get used to control and balance the flow of electricity to active pumps and compressors. Doing so prevents equipment failure and maximizes equipment life.

Littelfuse Intrinsically Safe Relays

Littelfuse intrinsically safe relays are UL 913 listed as associated apparatuses for interfacing between hazardous and nonhazardous areas. These high-quality products protect hazardous location circuits and are core components for intrinsically safe applications. The ISS-105 series is designed as a "smart" five-channel relay and pump controller, which can be configured for pump-up or pump-down applications. The ISS-102 offers two LEDs for visual indication of relay...
