Communication-capable Circuit Breakers

WL Configurator Brief Description

WL Circuit Breaker

WL Configuration software, WL Config©, is a software configuration tool used to set protective settings, set points and additional protective functions in the WL trip unit. It is designed for use on a Windows 2000 or XP PC with a minimum of 128MB RAM and a 1.2GHz or faster processor. The installation is a simple and intuitive process, with step-by- step instructions for the user.

WL Config runs in a web browser window, with the "Main Menu" tree below displayed at start-up:

After the program is installed on the PC, WL Config© communicates with WL Trip Units via the PC’s serial port. The COM16 MODBUS communication module is required for use with this software. An RS485 to RS232 converter is provided as part of the WL Config Software Kit (catalog number: WLCONFIG). WL Config uses the MODBUS protocol to communicate with the COM16 (typically at 19,200 baud, even parity and with a default MODBUS address of 126).

The internal CubicleBUS communications bus of the WL Circuit Breaker allows connectivity between the COM16, Digital I/O, Analog I/O, and Electronic Trip Units (ETU). CubicleBUS requires 24V DC+ power and provides a serial link to all the modules in the WL Circuit Breaker CubicleBUS system. 24V DC power must be available in the system for communication to exist between the PC and the COM16. The serial data generated by the Trip Unit is available at the COM16, which serves as a gateway to the CubicleBUS data.

The main purpose of WL Config is to configure the communication, protective and alarm programmable parameters of the WL Trip Unit, and also configure CubicleBUS Module parameters.

The parameters changed by the user and sent to the device are verified by the PC program and the device for a valid setting, and if out of range, an error message is displayed. Alarms can also be configured for any associated

I/O modules.

WL Config can interrogate a Trip Unit for instantaneous or historical data and display that information for user evaluation. If the system is equipped with the optional Metering Plus module, the voltage and current waveforms and any harmonic information can be viewed.

Note: WL Config can be also used in an offline mode, without a WL Trip Unit attached, to allow the configuration of a particular job to be completed and verified prior to downloading. This offers the advantages of quickly configuring many trip units with the same data and also provides organized electronic files for storing past configurations.

Siemens UL 489, UL1066 specifications WL Configurator Brief Description

UL 489, UL1066 specifications

Siemens UL1066 and UL489 are essential components in the landscape of electrical equipment, specifically in circuit protection and control. These standards ensure reliability, safety, and efficiency in various applications, including industrial, commercial, and residential settings.

The Siemens UL1066 is primarily focused on disconnect switches. These devices are designed to isolate electrical circuits, ensuring the safety of both personnel and equipment during maintenance or in case of faults. One of the key features of UL1066 disconnect switches is their high breaking capacity, enabling them to handle significant fault currents without failure. This characteristic is crucial in protecting downstream equipment from damage caused by short circuits. The UL1066 switches are also known for their robust construction, often featuring a metal enclosure that enhances durability and environmental resistance. Additionally, these switches can be operated manually or remotely, offering flexibility in operation and control.

On the other hand, Siemens UL489 circuit breakers provide comprehensive protection against overcurrents and short circuits. These devices not only interrupt fault currents but also protect connected devices from damage due to overload situations. Key features of UL489 circuit breakers include adjustable trip settings, which allow users to customize the response to overcurrent conditions based on specific application requirements. This adaptability makes them suitable for a wide range of environments, from large industrial plants to smaller commercial buildings.

Both UL1066 and UL489 products are constructed with advanced technologies, such as thermal-magnetic or electronic trip mechanisms in UL489 devices, ensuring precise and timely interruption of fault currents. These technologies promote energy efficiency and stability within electrical systems. In addition, many of these devices are equipped with indication features, providing clear visual status cues for quick assessment in emergency situations.

In terms of characteristics, both UL1066 and UL489 devices adhere to rigorous testing and certification processes to meet UL standards. This compliance assures users of their performance and reliability. Furthermore, the devices are designed to accommodate a wide range of operating temperatures and environmental conditions, making them versatile choices for various applications.

In summary, Siemens UL1066 and UL489 devices are paramount in ensuring safety and efficiency in electrical circuits. Their advanced features and robust construction make them indispensable in protecting both personnel and equipment in an array of industrial and commercial applications.
