ASTMD4459 UL-94VO IP66 Solar PV DC Rotary Isolator Switch 1000v 32A

Top sale Isolator IP66 Solar PV DC Rotary Isolator Switch 1000v 32A

Description: 

UKPD series DC rotary isolator switch are true DC switching isolators, not an AC type de-rated or re-wired for DC operation. What you have to consider is that any AC isolator is predominantly designed with materials chosen such that the load will be AC, this means that the load supply will be a 50/60Hz sine wave, whether it be 230Vac or 400Vac, etc. When switching AC it should be remembered that the nature of the load supply will always pass through 0Vac and therefore although loads can be arduous in type the supply is self extinguishing – by that I mean that even if the isolator switches at peak load and an arc between contacts is formed the action of the supply reducing to 0V means that the load will tend to zero and the arc be extinguished. DC load, on the other hand, is always there and unless the load becomes zero the power being pulled through the contacts will always be the same, so if the load is 500Vdc 25A it will be 500V 25A now, in 1s , in 1min, in 1hour – that is constant. If this is the case unlike the AC above if you switch “OFF” on load you will also be switching “ON” on load; DC does not go through a 0V level unless there is system supply failure (or some other fault).

13) The isolator has 4 seperate poles
14) Jumpers can be used to change the way that the poles are connected
15) Poles can be connected in series parallel or a variation of both series and parallel
16) Interconnection of the poles dictates the load that the switch can make and break
17) As the mumber of poles used increases so the load switching capacity of the device increases.
