Features and Applications Contactors Magnetic Contactors Full Voltage Features Horsepower rated contactors are available in NEMA sizes 00 through 6, plus three Furnas M-M motor matched sizes: 1¾, 2½, and 3½. These contactors can also be used on capacitor and transformer switching applications. See Application Data Section for rating information. Auxiliary Equipment • Field modifications such as auxiliary electrical interlocks, pilot lights, push buttons, selector switches and fuse blocks for low voltage pilot control are available to meet particular application requirements. • Normally open or normally closed power pole kits are available for sizes 0 through 1¾. • A full line of replacement parts is available including contact kits, coils and overload relays. • Rugged Industrial Design • Dual Voltage, Dual Frequency Coils • Front Removable Auxiliary Interlocks • Easy Coil Access • Horsepower Rating • Resistance Heating kW Ratings • Lighting Ampere Ratings • Capacitor and Transformer Switching Applications • Motor Matched Sizes • Straight Thru Wiring • Gravity Dropout • UL Listed 508 File #E14900 • CSA Certified File #LR6535 Applications Class 40 industrial magnetic contactors are designed for electrical loads such as heating, lighting, transformer and capacitor switching and AC motor starting. They control motors already protected by inherent or other types of overload devices. Used with appropriate pilot control, a contactor provides a choice of undervoltage protection or release. Class 40 contactors size 0 thru 6 feature carefully wound coils encapsulated to seal out moisture. Encapsulation also promotes heat transfer and resists electrical, mechanical and thermal stresses.

Features and Applications Contactors Magnetic Reversing Contactors Full Voltage • Rugged Industrial Design • Dual Voltage, Dual Frequency Coils • Compact Design • Front Removable Auxiliary Interlocks • Easy Coil Access • Straight Thru Wiring • Gravity Dropout • UL Listed 508 File #E14900 • CSA Certified File #LR6535 Application Class 43 industrial magnetic reversing contactors are designed for across the line starting of single phase and polyphase motors which do not require overload protection. These controls are available in NEMA sizes 00 through 6. In addition to the usual NEMA starter sizes Furnas offers four exclusive Motor Matched M•M sizes; 1¾, 2½, 3½ and 4½. These half sizes offer the same rugged, industrial construction as our NEMA sizes and ensure efficient operating performance. Furnas M•M sizes provide a real cost savings by cutting down on wasteful over capacity when NEMA sizes exceed the motor ratings. Typical applications include use with machine tools, material handling equipment, hoists and various production and industrial equipment as well as demanding automotive applications. These controls may also be used as changeover contactors on emergency power panels to transfer from commercial to standby power. Features Furnas reversing contactors size 0-6 include the following as standard. Molded Coil — Magnet coils are carefully wound and then sealed in epoxy. Encapsulation helps seal out moisture, promotes heat transfer and resists electrical, mechanical and thermal stresses. Dual Voltage/Frequency — Furnas contactors size 0-6 are available with dual voltage, dual frequency coils and are designed to operate on 50/60 Hz. Field Modifications Kits/Accessories — All reversing contactors can be modified in the field with a complete range of accessories. These include push buttons, selector switches, pilot lights, auxiliary electrical interlocks and surge suppressors. Size 0 through 4 Reversing Contactors The following features are characteristic of size 0 through 4. Gravity Dropout — For added reliability, the gravity drop out of the armature and contacts is assisted by stainless steel springs which help provide quick, precise opening of the contacts. 45 Degree, Wedge Action — The 45 degree, wedge action contacts reduce tracking and provide faster arc quenching. The resulting self cleaning and reduced contact bounce mean cooler operation and longer life for the silver cadamium oxide contacts. Terminal Design — Control terminals are self rising pressure type. Power terminal points are provided for use with power factor correction capacitors. Interlocks — Cross electrical interlocks prevent the simultaneous energization of both contactors. Mechanical Interlock — A mechanical interlock is provided to prevent both contactors from closing at the same time. Size 5 through 6 Reversing Contactors In addition to the standard features, size 5 through 6 reversing contactors incorporate many of the additional features listed for size 0 through 4 including side mounting auxiliary interlocks. Furnas size 5 through 6 reversing contactors use the reliable vertical lift magnetic action which has proven long life and trouble free performance. RSP-PRC003-EN 35
