Application
The 3LD2 switches are used in almost all power distribution systems for industry and infrastructure, but particularly those in main and auxiliary power distribution systems of commercial buildings and in domestic power supplies upstream of meters (e.g. SIPRO system).
Particularly for processing machines in mechanical and conveyor system engineering and in the chemical or food and beverage industries, these switches are now an essential part of the hardware architecture as main control and EMERGENCY STOP switches.
The 3LD2 switches can be used as follows:
-
ON-OFF switches
-
EMERGENCY STOP switches
-
Main control switches according to EN 60204-1
