MCCB molded case circuit breaker automatic instantaneous testing equipment

Short Description:

Automatic test: the equipment can automatically test the instantaneous protection function of MCCB circuit breakers without manual intervention.

Instantaneous Protection Parameter Setting: The equipment can automatically set different instantaneous protection parameters to meet the requirements of different circuits.

Measurement of Instantaneous Protection Action Time: The device can accurately measure the instantaneous protection action time of MCCB circuit breakers to ensure that it meets the specified range.

Alarm Function: The device can issue an alarm signal when the instantaneous protection action time exceeds or fails to comply with the regulations, in order to remind the operator to deal with it.
