Application - The Furnas Centurion 2000 offers a high new standard in definite purpose control  The largest, most complete line of definite purpose motor controls in the industry, it is ideal for many applications including: HVAC, Refrigeration, Elevators, Hoists & Cranes, Food Processing, Data Processing, Pumps & Compressors, Welding, Lighting, Pools & Spas.

Construction - The Centurion 2000 was designed to be a tougher, more compact, more versatile and quieter contactor than ever before.  Product features include:

  • Tougher Materials - The housing and all other non-metal body parts are made of bulk molding compound for greater strength and durability.
  • Compact - Space saving dimensions allow for smaller panels and more wiring room.
  • Straight Thru Wiring - Line terminals are located at the top and load terminals at the bottom.  This construction eliminates looping wires around the control and reduces wiring costs.
  • Interchangeable Mounting - The combination of multiple mounting holes and slots allow these contactors to be fastened onto panels and provide interchangeable mounting with many competitive contactors.
  • Terminals - Line and load terminals are supplied with pressure connectors.  Pilot control wires can attach to the line terminals by using integral auxiliary connections.  Oversize lugs are standard on 40A and optional on 25A and 30A.  You also have a choice of three terminal styles - box lug, binding head screws, or sems clamp.
  • Coils - Class H high temperature insulated coils are standard on 25A-60A contactors.  Vibration has been minimized by cushioning the coil and the enclosed construction reduces the possibility of failure due to contaminants.  Coils on 25-60A are equipped with combination pressure and quick connect terminals.  Electronic timers, surge suppressor or DC coil drivers are available built into the coils.  This option simplifies wiring and allows less panel space to be used.  

    Coils on 75-650A contactors are encapsulated in a moisture proof epoxy.  

    Some coils are equipped with combination pressure and quick connect terminals.  Connections are made by inserting the stripped wire under the screw head and tightening or by pressing on a quick connector.  

    Single voltage coils are standard for all popular voltages and frequencies.  Dual voltage, 120/240 or 240/480 volts, 50-60 Hz coils are available at an additional cost.  Dual voltage coils are standard on the 120-650A contactors.

    The 75A and 90A devices are also available with DC magnet and coil as an optional feature.  Magnet and coil assemblies are available for 6, 12, 24, 32, 115 and 230VDC. 
  • Magnet - The magnet is constructed of laminations of silicon steel.  A shading coil insures a positive sealing of the armature.  
  • Snap-On Accessories - Two snap-on electrical interlocks provide up to four SPST or SPDT circuits.  Interlocks snap on each side and are optional.  An optional mechanical interlock is also available.  Other accessories such as timers, coil snubbers, coil drivers and others provide versatile, expandable control.
  • Auxiliary Electrical Interlocks - Furnas supplies one or two interlocks as a factory modification or for field installation on 75A and 90A contactors.  Four auxiliary interlocks can accept 120-650A contactors.

OEM Pricing Available.
