Main switches
Main switches and
emergency-stop switches
A manual operated main switch must be provided for every mains circuit.
It must be a switch-disconnector corresponding to utilization category
AC23 (IEC 947-3) fulfils the following requirements:
• Disconnecting the electrical equipment from
the main.
• Visible contact indication or a disconnection function by construction
(the handle is in the “OFF” position when all contacts are open.
• If the main switch does not serve simultaneously as an emergency-stop
switch, its handle should not be red.
Black or grey handles are recommended.
• It should be lockable in the off-position (e.g. by padlock).
• All active conductors are to be disconnected from the main.
• The breaking capacity should be sufficient. In order to break the current
of the largest motor in a blocked state together with the sum of the
operating currents of the remaining
motors/loads.
• The handle of the main switch must be easily accessible and must lie
between 0.6 and 1.9 m above the incomer level.
Standards
Emergency-stop equipment
Complying with:
- IEC 947-3
- DIN VDE 0660
- low voltage directive 73/73 EEC
- low voltage directive EMC 89/336
EEC
The main switch may fulfil the function of an emergency-stop switch on
certain machines.
The handles must be red on a yellow background.
The contacts of manual operated emergency-stop switch has to be
opened by force.

Emergency-stop switches with undervoltage release
The cam switches with undervoltage release are equiped with a red/yellow lockout
handle for 3 padlocks.
The regulations EN 60204 part 1 and DIN VDE 0113 part 1, paragraph 7.5, demand an
undervoltage protection. This prevents at recovery voltage after mains failure or fall below
a set voltage level an automatic restarting, which can cause damage to the machine or
the working process. In the case of a mains failure the undervoltage coil operates a
mechanism which switches the main switch to the off position. The trip-free nature of the
mechanism ensures that the main switch can not be turned on in the absence of coil
voltage even when the switch actuator is operated.
