Definite Purpose Contactors

Product Overview

2-pole

4-pole

Bulletin 400

• Available in the following ranges:
      1-Pole: 20/25…40 A, 600V max.
      2-Pole: 20/25…40 A, 600V max.
      3-Pole: 20/25…90 A, 600V max.

The Allen-Bradley Bulletin 400 Definite Purpose contactors are specifically designed for applications such as air-conditioning, refrigeration, resistive heating, data processing and food service equipment, pumps, and compressors.

Box lugs are standard on 40 A contactors and larger. A maximum of two auxiliary contact blocks (one on each side, four contacts max.) can be field installed.

Features Include:

• UL tested for lighting loads
  
• Compliant with international standards
  
• Standard and high fault short-circuit current rating (SCCR)
