Contactors type CPO, CNP are used for closing and
opening operations of the control circuit as well as for
the control of small size motors and other a.c. and
CM, CNM contactors are intended for switching and
control of three-phase motors and other a.c. loads
such as electric ovens, bulbs, electromagnets, capacitors
Contactors of the type CNB are suitable for d.c. operated
(special electromagnet) and for particular conditions of
application where reduced noise at closing operation
and complete elimination of noise in closed position
are required. These noisless contactors are particulary suitable for
use with passenger lifts. Closing and opening operations are affected by an
electromagnet thus the contactors are primarily suitable for remote control and automatic operation.
Contactors should be installed in dry and clean areas..
