SWITCH DISCONNECTORS

Can switch disconnectors be combined together to make 6 or 8-pole switch changeovers (I –0–II)?

Certain applications require the use of 6 or 8-pole switch changeovers with a
I - 0 - II function to switch over between supply lines.
LOVATO Electric has a modular solution: purchasing two standard switch disconnectors of the same rating and the GAX50… or GAX60… accessory, either 6-pole switch disconnectors or 3-pole switch changeovers can be made. By adding the fourth pole, with snap-on mounting to the switch side,
8-pole switch disconnectors and 4-pole switch changeovers can be assembled.
The main function of 6- and 8-pole switch disconnectors is to simultaneously disconnect two lines or electric circuits. For this reason, it is very convenient to be able to carry out the isolation of the 6 or 8 poles directly with one single operation (one only handle and one only actuating mechanism).
The typical I – 0 – II function of switch changeovers is the on-load switching over between two low-voltage power circuits as well as their safe disconnection.
 

What colour should the operating handle of a main load switch be?

The handle of a main load switch must be black or grey. The red-yellow handle indicates the main load switch is also used as an emergency switch, required only when there are risks of electric shock.
