IEC 60669-1 Three Stations 300V 30A Load Cabinet For Switch Life Tester
IEC 60669-1 Three Stations 300V 30A Load Cabinet for Switch Life Tester
Equipment Introduction:
The load cabinet is designed and manufactured according to IEC60884-1, IEC61058-1, IEC60669-1 and etc.
It is applicable for household and similar fixed electrical installations switches and plug sockets breaking capacity and normal operation test, the rated voltage of the switch is not greater than 280V and the rated current less than 16A. The purpose is assessing whether the switch is able to withstand the normal use of mechanical damage and electrical fatigue damage, and whether the contacts has adhesion phenomenon, long-term closed or disconnected phenomena, to examine whether the test samples excessive worn and have other harmful consequences.
The frame of the load cabinet is white. The control panel in one the front top of the cabinet, there are power switch/current/voltage and power/power factor displaying instruments, load power switches, status indicators, start and stop buttons, capacitance switches, load switches and alarms etc. Below corresponds to the output voltage regulation knobs, output current regulation knobs and power factor regulation knobs. The load box has three independent stations, each with resistive, inductive and capacitive (fluorescent type) load three in one feature, they are switchable. The interior of the load cabinet is cooled by strong wind convection cooling. At the back of the load box there are wire connecting terminals, the load cabinet outputs current voltage and power during the detection by connecting the wire with the test samples on the endurance test machine.

Application:
Used to provide adjustable load voltage, current and power factor during mechanical-electrical contact system test. it is suitable for breaking capacity and normal operation endurance test of switches, plugs and socket-outlets for household and similar fixed electrical installations, and electrical stress test for luminaries and other similar tests. This series of resistive, inductive, capacitive load cabinets should work with Sinuo's plug, socket and switch endurance test equipment.
