NEMA Full Voltage Non-reversing Contactor, Size 0, Cat. No. N111BS0X3N

Product Description

The Cutler-Hammer Intelligent Technologies (IT.) Electro-Mechanical Con- tactor by Eaton Corporation consists of an IT. Electro-Mechanical Contact Block and IT. Electro-Mechanical Coil Controller as a Full Voltage Non- reversing (FVNR) or Full Voltage Reversing (FVR) device. Size 00 to Size 4 Contact Blocks combined with Coil Controllers (factory or field assembled) are stand-alone Contactors. Only the Size 5 Contactors have internal factory assembled coil controllers.

Features

■Size 00 – 5, 9 – 270A, 2 – 200 hp, 600V

■24V DC Coil Control — safe, reliable global standard

■Frame width (mm): 45, 54, 76, 105, 140

■No laminations, shading coils or magnet noise

■-40 to 149°F (-40 to 65°C) operating temperature

■No seal in auxiliary contacts required — control wiring is not needed between the contactor and overload relay

■Conformal coated printed circuit boards for resistance to harsh environments

■Unique Pulse Width Modulated coil controller minimizes coil power consumption

■Microprocessor-based control

■Easily accessible mounting feet for panel mounting

■Meets or exceeds global standards for EMC (Electromagnetic compati- bility) immunity and emissions

■Front and side mounted Auxiliary Contacts: 1NO, 1 NC, 2NO, 2NC, 1NO/1NC and logic level

■2- or 3-wire control

■Built-in logic to provide either 2- or 3-wire control, eliminating the need to provide and wire auxiliary con- tacts to seal in and interlock the contactor coils

■Easy field assembly of control wiring — plug and unplug lockable control connector

■DIN rail mounting for Sizes 00 – 2

■Optional mounting plates for Size 00 – 4

■Common accessories

■Long-life silver nickel and silver tin oxide contacts provide excellent conductivity and superior resistance to welding and arc erosion

■Environmentally friendly materials

■Low wattage coils and minimal heat dissipation

Reversing Contactors

■Includes Reversing Power Wiring and bus bars

■Mounting plates for Size 00 – 4

■Exclusive internal electronic inter- lock for reversing

■Field installed Reversing Kits

■Unique coil controller energizes both forward and reverse contactors

— one control point for wiring
