Product Description
Acrel ARD3M low voltage 3 phase motor control motor protection relays
In today's world of manufacturing, motors provide the majority of power that is used to convert raw materials into finished goods.
In fact, over 50% of the work completed in today's manufacturing plant is completed by electric motors.
It is estimated that this percentage will continue to increase for the foreseeable future.
With this great percentage of manufacturing capability relying on electric motors, it is important to ensure that motors and their circuits are properly protected to provide maximum operating time and minimum downtime.
Improperly protected motors/circuits in today's modern manufacturing plants can mean production downtime losses from hundreds of dollars to tens of thousands of dollars per hour besides the cost of in-process material that can be destroyed.
It is no wonder that over the last several years, an enormous amount of effort and resources has been used by control manufacturers in the development of imp
