The Compac Engineering ERECTA SWITCH Series 20 Pump Control System is designed to handle industrial control jobs like switching contactors, motor starters and solenoid valves. 20s use the Yaskawa Control Bestact™ hermetically sealed switch element.
All Compac Engineering series 20 switches can operate with a 3 amp inductive load!
20 Series use a common parts set and assembly style. Complementary Compac Engineering ERECTA SWITCH components make length, switch action, switch position, mounting and electrical interface a matter of choice. Disciplined assemblies and precision parts make field repairs practical.
20 Series switches and pump control configurations are valuable in AC and DC industrial control applications where compact size, corrosion resistance, long life and repairability are important for high-low pump control, electroplating, semiconductor processing, diesel day tanks, etc...
