The course is primarily aimed at maintenance and operating supervision personnel. Participants will learn the design, functional principal and operation of the 3WL and 3WA circuit breakers as well as how to inspect and maintain it, identify faults and exchange spare parts if required. Basic knowledge of low-voltage protection technology and circuit-breaker communication are trained.
Objectives
The course aims to give participants specialized knowledge about the maintenance and operation of 3WL and 3WA circuit breakers. The basic knowledge of low-voltage protection technology and circuit breaker communication is trained ready for use.
