ELECTROSWITCH
TYPE WL LOCK-OUT RELAY
The Type WL Lock-Out Relay product line was also acquired from Westinghouse in 1988.
Countless Type WLs are still providing reliable protection in older facilities decades after they
were first installed. Electroswitch is pleased to announce that we can provide replacement
units for most of the WLs still in service. Please contact us with the WL part number of the
switch you are replacing and we will be happy to respond with an approval drawing or a
suggested replacement if your WL cannot be duplicated.

TABLE II: COIL OPERATING CHARACTERISTICS
Coil part numbers must be specified at the time of order. Those marked with an asterisk (*) are considered
to be standard for the operating voltage indicated. These coils should not be used for 5 ampere series
trip operation from secondary of current transformers, as the burden is too great. Time is in milliseconds.
Time may vary slightly for AC tripping, depending on point of AC cycles at which the coil is energized.
