NTC-08.47.1/8 “Installation of protective grounding, nulling and cutout devices”

The plug-in panel is designed to obtain basic knowledge about the operation and connection of protective cutout and grounding devices. The panel allows to install the investigated devices in the electric service box, connect and electric load via cable trunk. It’s possible to check single and three-phase devices

The front panel includes:

• metal electric service box ЩРН-12;
• 3-position switcher (PK407);
• direct bulb-holder Е27;
• cable trunk;
• a set of clamps;
• DIN-rail, with the following equipment mounted:
  • automatic circuit breakers (single and three-phase);
  • protective cutout devices (single and three-phase).

Possible experiment

1. Studying the operation principle and checking up of a single-phase automatic circuit breaker.
2. Studying the operation principle and checking up of a three-phase automatic circuit breaker.
3. Studying the operation principle and checking up of a single-phase protective cutout device.
4. Studying the operation principle and checking up of a three-phase protective cutout device.
