3WL

3WL are air circuit breakers. They can transfer important information to the software to carry out diagnostics management, fault management, maintenance management, and cost center management.

Connect the 3WL air circuit breakers via COM35 or COM16. You can use any other gateway to establish the connection.

The circuit breaker status is displayed in powermanager and the measured values and can be switched with the appropriate authorization.

There are two switching functions:

ON - Select ON when the circuit breaker status is OFF or TRIPPED.
OFF - Select OFF when the circuit breaker status is ON.

For more information, refer to the 3WL/3VL system manual.

State symbols of the molded-case circuit breaker

Different states of the molded-case circuit breaker are represented as a circuit breaker symbol. The state symbol of the molded-case circuit breaker indicates the position of the molded-case circuit breaker in the frame. You can see whether the molded-case circuit breaker is open or closed. The background color designates the status of the relevant message.
