WL Circuit Breaker selection and application guide
Characteristics table
Wire connection type Number of wires and sizes
Secondary Screw compression 1 x 14AWG or 2 x 16AWG
disconnects Tension spring compression 2 x 14AWG
Ring lug terminal 2 x 14AWG or 2 x 16AWG
or 1 x 10AWG
PROFIBUS or MODBUS communication
PROFIBUS or MODBUS communication requires a COM15
or COM16 converter to retain WL data in temporary buffers
for transmission to external PCs or PLC monitoring systems.
External communication connection to either module is
through a DB-9F connector.

Cradle accessories and options
Dual key breaker locking
For draw-out breakers, a cradle mounted breaker lockout device
can be used with single or dual key cylinders. One key cylinder
holds the key captive when the breaker is closed and releases the
key when the breaker is opened. The other key cylinder locks the
breaker from being removed from its breaker compartment. The
key is removable when racked into the disconnect position. Key
cylinders can be keyed alike or unique for interlocking with other
breakers in the distribution system. Superior or Kirk Key lock types
are available. Custom keys must be supplied by others.
The following items are available for WL cradles. Items are
described to highlight the functional characteristics of these
factory installed cradle options.
Secondary disconnects
Secondary disconnects are used to interconnect external breaker
control and signaling circuitry to the WL breakers factory wired
circuitry. Three types of external connection terminals are
available. 1. Screw compression for bare wire, 2. Tension spring
compression for bare wire and, 3. Captive screw connections for
Siemens type ring lugs (WL10RL).
Isolation shutters
When removing a draw-out breaker from its connected position
the primary contacts become exposed and more accessible to
personnel in the breaker compartment. Isolation shutters reduce
that accessibility to the primary terminals by automatically
closing the access ports to the primary terminals while the
breaker is in the test or disconnect positions. After removal
of the breaker from its compartment, the shutters may be
padlocked to inhibit manual shutter opening while breaker is
not in the compartment.
