Description
Sentrysocket provides a high level of protection against electrocution and gives
further protection when used with appliances vulnerable to insulation damage,
particularly when they are in damp environments or outdoors. The Sentrysocket
units are not suitable for mounting in damp environments or outdoors.
Sentrysocket, incorporating an RCD, is part of a complete range of fixed and
portable wiring devices and circuit protection devices suitable for use in domestic,
commercial and light industrial applications.
Active control circuits
Incorporate a ‘Re-set’ mechanism and are mains failure sensitive, i.e. they will
function under all the normal conditions expected of an RCD, but will also trip in
the event of a power cut or a sudden, dramatic reduction in mains voltage. This
makes them ideal for use where it would be hazardous for equipment to suddenly
energise after return of mains power, such as use with rotating machinery and heat
developing apparatus.
Passive control circuits
Incorporate a ‘Stay-set’ mechanism and is mains failure proof, i.e. it will function
under all the normal conditions expected of an RCD and will not trip in the event
of a power cut. This makes it suitable for use with freezers or in inaccessible or
unmanned locations.
Cable management
Logic Plus™, Albany Plus™ and Metalclad
Plus™ Sentrysockets can be mounted in a variety
of MK trunking systems.
Installation
Flush mounting steel wall box
It should be noted that some of the conduit
entries may be restricted, depending upon their
positions and the depth of box used.
