Test equipment capable of OCR and GR testing!
The "OCR-50CK" is an overcurrent and ground fault relay testing device that can perform OCR and GR tests with a single unit. It is specifically designed for current relay testing, making field testing easy, and features convenient breakers for the power supply and auxiliary power supply. The ammeter uses a true RMS conversion method with a moving coil type, making it easy to read with evenly divided scales. It adopts a new high-performance counter, and the connection for test leads is made via connectors, all color-coded for clarity. With optional combinations, it is possible to conduct AC withstand voltage tests, voltage relay tests, and directional ground fault relay tests. Please feel free to consult us. 【Features】 ■ Uses breakers ■ Adopts moving coil type ■ New high-performance counter *For more details, please refer to the catalog or feel free to contact us.
