■ Application
The 3LD switches are used for switching main and auxiliary
circuits, but also for switching induction motors and other loads
during maintenance and repair work.
They are manually operated switch disconnectors according to
IEC 60947-3/VDE 0660 Part 107 (EN 60947-3) and comply with
the conditions for switch disconnectors.
The 3LD can be used as
• ON-OFF switch
• EMERGENCY-STOP switch
• Main control switch according to EN 60204-1
17/14
In EN 60204-1 (VDE 0113 Part 1), main control switches are
called "mains isolating devices", while EMERGENCY-STOP
switches are termed "devices for emergency shutdown".
Maintenance personnel can protect themselves against
unauthorized startup with padlocks (up to three can be fitted).
3LD main control and EMERGENCY-STOP switches are
approved according to UL 508.
* You can order this quantity or a multiple thereof.
