Communication-capable Circuit Breakers

WL Circuit Breaker

External CubicleBUS Modules

By connecting additional, external modules to the CubicleBUS, breaker status information can be displayed and data read from the switchgear to the system. This enables cost-effective solutions to be implemented

for automating other devices in the switchgear.

General

External CubicleBUS modules enable the WL Circuit Breaker to communicate with secondary devices in the switchgear. They can be used, for example, to activate analog displays, transmit circuit breaker status and cause of trip, and read additional control signals. One module is also available for zone- selective interlocking.

Five different CubicleBUS modules can output data from the CubicleBUS system (four digital output modules and one analog output module). A digital input module can transmit data from the switchgear to the MODBUS master, and a ZSI module enables zone selective interlocking among the circuit breakers.

Rotary Switches

With the exception of the configurable output module, all external CubicleBUS modules are configured using rotary switches.

The arrow on the rotary switch points to the function that is currently active. With certain modules (e.g. digital output modules), the group selection (e.g. "1st Module" left; highlighted) and then any other settings (e.g. time delay) must be taken into account. More information on this is provided with the individual module instruction sheets and the WL Instruction Manual.

Installation

The external CubicleBUS modules can be installed onto a standard 35mm DIN rail on the panel.

The cable for connecting the first module to the circuit breaker must be no longer than 2 m.

Prefabricated cables, which can be ordered separately in different lengths, must be used to connect the CubicleBUS modules

to each other and to the circuit breaker. These cables enable the various components to communicate and supply the CubicleBUS modules with 24V DC.

In this example, the rotary switch

2-5

has been set to function “0.2”.

Figure

All external CubicleBUS modules have the same housing. The CubicleBUS can be connected

to X1 and X2 with an RJ45 plug or a terminal connection made to X3. This depends on

2-10

whether a COM16 module is available.
