Modular hybrid motor starters streamline installation
Contactron pro (photo) is a hybrid motor starter that simplifies wiring and safety integration. The auxiliary contact modules allow feedback of the motor state and implementation of self-sealing motor circuits. When used with the PSR-MC38 safety relay, the Contactron pro can easily permit a SIL 3/PLe group of emergency shutdowns via one interface. Like the original Contactron, the pro modules incorporate this company’s Hybrid Technology, which offers three-phase motor switching up to 5 hp. Compared with traditional contactors, it reduces wiring time and space by up to 75%, says the company, adding that the device has a service life of up to 30 million switching cycles, which is up to ten times the service life of electromechanical solutions. — Phoenix Contact USA, Middletown, Pa.
