Selection of Reversing Contactors for Resistive Loads
Three- and Four-Pole Contactors for AC Control Circuits
The tables below show general purpose and sensitive-environment three-pole reversing and four-pole
change over contactors for AC control circuits. The sensitive-environment contactors are recommended
for use in areas sensitive to noise, high interference mains supplies, and so forth. The contactors
incorporate an integrated mechanical interlock.
Both types of contactors mount on 35 mm DIN rails or with 4 mm (# 6) screws. The wire termination
screws are in the open, “ready-to-tighten” position. In addition, the sensitive-environment contactors
include a coil with a built-in rectifier and suppressor. Customer wiring is required to connect coil
terminations to the electrical interlock; see page 60 (top row, center wiring diagram).
For information on add-on auxiliary contact blocks and accessories, see page 54 to 58.
