The TR1760 Murphymatic® Transformer Relay Assembly is an Electric Motor Controller. It is ideal for controlling a variety of electric motor driven applications, and is recommended for use on salt water disposal systems, waterflood systems, and many others.
The TR1760 can be used with electric motors or driven equipment which is started and stopped from a remote, normally open Swichgage®. When the TR1760 is used with a Murphy Analog Swichgage®, it allows for visual reading of operating conditions, and provides an adjustable differential between high and low settings throughout the Swichgage® dial range. All internal control circuits are completely pre-wired and relays are plug in type to facilitate field servicing. A NEMA 1 enclosure is standard.
Some of the features and specifications of the TR1760 are as follows:
* The panel contains a heavy-duty transformer with multiple primary taps for easy connection to most any available AC power source.
* 24 VAC Low Voltage secondary control circuit with terminals for remote auxiliary switches.
* Plug-in relays have three SPDT silver cadmium oxide contacts providing long life reliability.
* Power relay has extra heavy silver cadmium oxide contacts rated 10 amp, 480 VAC.
