The course aims to give participants specialized knowledge about the maintenance and operation of 3WL air circuit breakers.
It is primarily aimed at maintenance and operating supervision personnel. Participants will learn the design, functional principal and operation of the circuit breaker as well as how to maintain it, identify errors and exchange spare parts if required.
In addition to this, selected functions of the 3WL10 circuit breaker (size 0) will be presented and an overview given of the air circuit breaker communication options.
