Switch Disconnector
The switch-disconnector is largely used as the main switch in low voltage switchgears for distribution of power, starting and stopping motors and isolating loads during maintenance. they are also enclosed in metal or plastic boxes as safety switches to ensure that accidental start of machines is prevented. The range from 16 to 160 Amp are either base plate or door mounted by snap-on or screw fitting. Front operated 3-, 4-, 6-, 8-pole and change over types are available as standard.
From 200 up to 3150 Amp the switch-disconnectors, also called load break switches, are designed as pole modules and they are available as 1- to 4-pole verisons, front or side operated.
