3WL10 product and mounting versions
The 3WL10 circuit breaker is available in two product versions:
● Air circuit breaker
● Non-automatic air circuit breaker
The following mounting versions are available:
● Fixed breaker:
In the case of fixed breakers, the circuit breaker is permanently installed in the
switchboard panel.
● Withdrawable breaker:
The withdrawable breaker comprises a fixed part (guide frame) and a movable part
(circuit breaker). This permits fast disconnection of the circuit breaker from the power
system for quick replacement or for maintenance without disassembly work and thus
ensures high availability of the installation.
