WL Circuit Breaker selection and application guide
Breaker display adapter (BDA)
The BDA can be used to read or modify the breaker ETU and
Cubiclebus parameters using a laptop, pocketPC or remote
desktop PC. All circuit breakers in a system can be parameterized
individually using one BDA with similar or different parameters.
No software is required as the embedded software interface
is through a PC browser. Connectivity to a PC or network can
be serial (RS232) or Ethernet (TCI/IP) addressed. A separate
120VAC in/ 24VDC out power supply is included. If the breaker
ETU is energized with 24VDC control power the BDA can be
powered through the interconnected ribbon cable. Order part

Low Voltage Circuit Breaker
Accessories
Handheld test device
To test the WL breakers ETU trip functions we offer a hand-held
tester that checks:
• Current Sensor Winding
• Long-time Function
• Short-time Function
• Instantaneous Function
• Neutral and Ground Fault Function
• General ETU system check
During a test the device will electrically trip the circuit breaker
simulating a full function test of the ETU and the trip actuator.
Cables for 120VAC power supply and ETU connection is included
with the tester. Order part number WLTS
Communication and metering power supply
For WL devices that require a 24VDC input we offer the Siemens
SITOP power supply. The SITOP power supply is a class 2 rated
devices suitable for supporting loads of 2.5 or 3.8 amps. DIN rail
mounting provision and compression wire connections included.
For loads of 2.5A maximum order part number WLSITOP25 or
WLSITOP1 for 3.8A maximum loads.
Mechanical breaker interlocks
A mutual mechanical interlocking option is available for fixed
or draw-out breakers. Interlocking is managed through cable
connections between two or three adjacent breakers 6 meters
apart or less. Lock kit includes 2.0 meter interlocking cable and
mechanism for mounting to a single breaker.
For fixed breaker frame size 1 order part number WLNTLKF1
For fixed breaker frame size 2 or 3,
order part number WLNTLKF23
For draw-out brearker frame size 1, 2, or 3,
order part number WLNTLK
For cable extensions, order part number
3.0 meter WLNTLWRE3
4.5 meter WLNTLWRE4
6.0 meter WLNTLWRE5
