Profile: Macromatic Industrial Controls, Inc. manufactures & sells control and monitoring products for a variety of industrial & commercial applications. Phase monitor relays which are also called three phase monitors, phase loss relays, protective relays and motor protection relays. They provide motor protection against premature equipment failure caused by voltage faults on 3 phase systems. These devices are designed to be compatible with most Wye or Delta systems. These relays protect against unbalanced voltages or single phasing regardless of any regenerative voltages. Our time delay relays are available in three types such as plug-in, 1/16 DIN and 17.5 mm modular. Plug-in time delay relay works with industry standard 8 & 11 pin octal or 11 pin spade (blade) sockets.
