Load feeders with integrated safety tech- nology are also known as safety relays with power contactor enabling circuits. They in- corporate the combined performance of our electronic safety technology and the SIRIUS modular system. The combination of a cir- cuit-breaker and two contactors connected in series results in a fuseless, ready to install, pre-wired, tested and certified load feeder. Built-in diagnostic capabilities and monitor- ing systems ensure fast error detection and a high degree of machine and plant avail- ability. Safety-oriented load feeders facilitate in-service switching and can also be expan- ded. They combine the functions of a motor starter and an emergency stop circuit in small machine tools and processing machines.
