Latched Contactors
There are some applications where it is not desirable to dis-
connect the motor from the line during voltage depression.
These applications are generally those associated with a
critical drive where the continued rotation of the drive may
be more important than possible damage to the motor from
low voltage.
The mechanical latch maintains contactor closure under the
most severe undervoltage conditions, including complete loss
of voltage. Latched contactors may be specified if required
by the application. The standard close and trip coils are
designed for use on 120 volts rectified AC or 125 volts DC.
Trip coils are also available in 24V, 48V and 220V DC. A manual
release feature is provided as standard. Capacitor trip devices
can also be used for release on the trip coils.
The Limitamp latched contactors are identical to the unlatched
versions, with the exception of a small latch attachment
mounted on the contactor, which slightly increases the depth
of the contactor.
