Main 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:
Main switches
• 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.

Complying with:
- IEC 60947-3
- EN 60947-3
- DIN VDE 0660 Teil 107
- 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.

Enclosed switches
The maintenance switch is an enclosed main switch with locking handle by 3 padlocks.
With red handle and yellow front plate, if it should be used as an emergency-stop switch,
otherwise black/grey.
There are six sizes of standard enclosures for the series ML. Each is equipped with a cover
coupling and a double PE-terminal.
All enclosures have a degree of protection IP65 and are of solid impact and flame resistant
polyester.
