Filter Sockets
Thermal Overload Cut Out.
The “Voltage Spike and RFI” Filter
Sockets are fitted with a thermal overload
cut out. The thermal cut out will operate
when an overload causes the product to
overheat. The thermal cut out will
automatically reset as the product cools
and the overload is removed.
Replaceable Spike Filter Cassette.
The “Voltage Spike” Filter Sockets are
fitted with a replaceable Filter Cassette,
located in the top edge of the product.
The MK Filter Socket, in common with
other filters, uses Voltage Dependant
Resistors for spike suppression purposes.
The performance of these devices will
eventually degrade with use to a level where
they will no longer provide adequate
protection. When this occurs the spike filter
performance of the MK Filter Sockets can
be restored by replacing the Filter Cassette.
When the Filter Cassette needs replacing
the indicator on the Replacement Filter
Cassette will glow Red or go out, an audible
beep every 5 seconds may also be heard.
Only remove the old Filter Cassette when
a new MK replacement Filter Cassette
(List No. K1800), is ready to be installed.
Note: As with all filters, these Filter
Sockets will reduce the magnitude of RFI
and spikes and consequently their ability
to interfere with connected equipment.
They will not completely remove the
interference from the supply.
In the interest of safety this product should
be installed by an electrically competent
person, (eg. a qualified electrician).
If in any doubt, please contact MK
Technical Sales Service Department on
