How small switches like this can be used to control heavy loads especially in public lighting?
This switch is looking small since it is essentially with an electronic content rather than electrical in nature and is in tune with the modern approach of miniaturization. The size has no real bearing on the performance. Size is psychological and the performance is real. Electric Irons, cellular telephones, transistors, televisions, laptops and all such devices are becoming more and more small in size and the world prefers them. This switch can handle directly up to 3 kW and a contactor can be attached if the load is more. This ensures a lesser cost when compared to any other solution and yet gives the ideal performance. The integral model SWADEEP 02-EC offers the solution for higher lamp loads. This model SWADEEP 02-EC comes with a contactor, MCB, terminal connectors, cable glands, an openable door with window, lock and key, pole mountable brackets etc.
