Description
High current testing device HCTD-20M designed for testing ampere-second characteristics of circuit breakers by AC current at 50 Hz frequency up to 20 kA.
Devices allow registering the value of output current and timing the automatic circuit breaker switching interval.
Also devices may be used as an adjustable AC current source up to 20 kA for power circuits with low impedance.

High Current Test Device HCTD-20M provide a short duration output through a typical circuit breaker when an instantaneous trip element must be tested.
Sufficient current is available for testing time delay characteristics of motor overload relays and circuit breakers.
The intuitive control makes the test set easy to operate.
Sensing leads, which operate on either normally-open or normally-closed devices, are connected to the test object auxiliary contacts or open breaker pole. The output current level can be easily preset.
When the output is initiated, the preset output current locks on and the timer starts. When the test set senses a change in state of the test object auxiliary contacts (NO to NC or NC to NO), the current shuts off and the timer stops.
High current device HCTD-20M can be used as a universal current source up to 20kA.
