Introduction

Developed on cutting-edge technologies, Eatons W-SLC withdrawable typevacuum contactor-fuse combination units are world leading in terms of performance,safety and functionality. The W-SLC vacuum contactor-fuse combination units areapplicable in AC systems with voltages up to 7.2 kV and 50/60 Hz. They canbe used in frequently operated heavy loads and harsh environments.


5/125

Product safety featuresThe contactor is prevented from closing and a panelindication is provided when:

Fuse blown and or Fuse not fitted

Additional interlock options are available to interfacewith the panel if appropriate panel designs are incorporatedsuch that:

The truck is prevented from being racked in if: - The front door is open - The earth switch is ON The earth switch cannot be switched ON if the truck is

in the Service Position. The panel door cannot be opened if the truck is in

the Service Position.

ApplicationsW-SLC vacuum contactor-fuse combinationmotor starting applications:

Squirrel-cage induction motors Synchronous motors Wound-rotor motors

Suitable for: Full voltage starting Reduced voltage starting

The perfect choicefor all applications HVAC Mining Automotive Petrochemical Pulp and Paper

Pumps, Fans, Conveyors and Crushers
