Produce details: Model ZLT-AH1
To determine testing resistance to abnormal heat of insulating sleeves of plug pins, in according to IEC 60884 1 figure 40,
This test apparatus consists of an insulating plate A and of a metal part B: between these two parts an air space of 3 mm shall be provided and this distance shall be obtained through means which do not impair the air circulation around the pins.
1 insulating plate A, which round and flat, thick 5 mm, have a diameter equal to twice the maximum permissible dimension of the engagement face of the plug given in the relevant standard sheet,
5 metal part B, brass, length at least 20 mm, the same shape as the maximum outline of the plug according to the relevant standard sheet,
1 thermocouple, type K, is inserted at a distance of 7 mm from the front surface of the metal part B in a symmetrical position
Power supply : 220V 50Hz or 110V60Hz, other voltages on request.
