PV SWITCH-DISCONNECTOR
DC isolators have been specifically designed to switch direct current(DC) at voltage up to 1000V, their robust design and ability to switch such voltages , at rated current , means that they are ideally suited to be used in the swtiching of photovoltaic (PV) systems.
Key Features:
IP66 NW rated enclosure.
Ample internal space for easier wiring.
Unique spring loaded switching mechanism for high speed switching.
Knife edge self-cleaning contacts for increased switch life.
Long arc chambers to help rapid arc suppression.
The switch has 4 separate poles.
Links can be used to change the way that the poles are connected. Poles can be connected In series or parallel or a variation of both series and parallel.
Interconnection of the poles dictates the load that the switch can make and break.
As the number of poles used increases so the total load switching capacity of the device increases.
DC isolators switch instructions:
It is important to ensure that all electrical connections (including factory connections) are tight , ensure that all terminal screws are tightened firmly.
It is recommended that for DC, multi-stranded cable,crimp ferulesare used to ensure that the wires do not become loose,loosecables can cause excessive watt loss and generate excessiveheat causing severe damage to the switch.
After installing and wiring the switch carry out the following test : switch on and off several times making sure that a positive snapaction can be felt and heard.
If the switch cannot be felt and heard to operate correctly then itis important that che switch is not used.
