1. Equipment introduction

Equipment Features: This panel can be used by teachers in the classroom, and also by students to easily learn and test the actual protection of electrical equipment, ensuring the safety of personnel and systems, as well as the continuity and quality of power supplied to electrical equipment. Panels provide the means to verify technical regulations and related technical standards.

The various electrical devices installed, partially connected to each other and with safety terminals, operate with very simple and fast operations, offering the possibility to create, modify and check the installed safety devices.
