Product Summary

High current testing device HCTD-3M designed for testing ampere-second characterization of circuit breakers by AC current at 50 Hz frequency up to 3 kA.

Product Description

High current testing device HCTD-3M designed for testing ampere-second characterization of circuit breakers by AC current at 50 Hz frequency up to 3 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 3 kA for power circuits with low impedance.

Maximum output voltage 7 V (50 Hz)
Maximum RMS output current 3,0 kA
Output current measuring range ("A" mode) 10 А - 1000 А
Output current measuring range ("kA" mode) 1 kA - 3 kA
Power consumption, max 5 kVA
Test current duration measuring range 50 ms - 990 ms;
1 s - 7200 s
Current measuring accuracy 1,5 % of range
Duration measuring accuracy 3 % of reading
Max. testing duration at max. output current 10 s

340x210x140 mm
250x220x115 mm
Busbars S=110 mm2, l=1 m 4 pcs.

High Current Test Device HCTD-3M 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-3M can be used as a universal current source up to 3kA.
