Function
Contactors are electromechanically
controlled switches used to control
single or multi-phase (high) power
loads while the control itself can
be (very) low power.
Applications
Switching of lighting, heating-equipment, motors for pumps and fans, ...
Day and night contactors are used mainly in combination with dual-tariff
applications to allow high-energy-loads (i.e. electrical water heaters,
accumulation heaters) only to consume energy during the low-tariff period.
A forced-on, forced-off, auto-switch allows to overrule the normal operation of
the DN-contactor at all times.
Features
Except for the 20A version, all contactors have DC coils, resulting in an abso-
lutely noise-free, real silent operation: 50 or 60Hz noise generation by the con-
tactor is impossible. As all DC coil contactors have an internal diode rectifier
bridge, they all can be operated by both DC and AC power supplies. The built-
in varistor protects the coil against an overvoltage of up to 5kV.
The switch position of the contactor is visualised through an indicator flag.
The loss-proof safety terminals are equipped with Pozidriv screws and have
IP20 protection degree. Add-on auxiliary contacts as well as spacers and
sealing pieces are available.
Standards
IEC 60947-4-1, BS EN 60947-4-1, IEC 61095, BS EN 61095. Approval VDE.

Remark: If several contactors are mounted next to each-other and the time of operation exceeds 1 hour and the ambient
temperature rises above 40°C, a 1/2-module spacer must be added every second contactor (I.e. contactor contactor spacer
contactor contactor spacer contactor contactor etc.)
