Kew Technik has introduced the Socket & See SOK 60/16HD, a heavy duty 400V, 16A tester for checking the sequence of rotation and presence of all phases and earth in three phase electrical supplies.
With its tough polycarbonate casing protected by a rubber holster, the SOK 60/16HD is also suitable for checking the safety of three phase supplies provided to trucks and coaches.
The SOK 60/16HD comes with a 16A BSEN 60309 (BS 4343) four pin plug moulded onto the test lead, ensuring a safe connection to the socket under test. An adapter is also available enabling the SOK 60/16HD to test 32A socket outlets.
The unit produces an instant phase sequence indication, with three green LEDs rotating clockwise and a continuous tone indicating clockwise phase rotation. Three red LEDs rotating the opposite way and a warbling tone indicate anti-clockwise phase rotation with each phase clearly identified as L1, L2 and L3 in accordance with current European practice.
