KDQ-310: This device is detecting earth leakage by zero phase current transformers, which can be connected up to 16 sets. Alarm and buzzer to be activated if measured current from ZCT is exceed setting value.

– Measuring functions: Voltage, current, leakage current, active/reactive/surface power, PF, frequency, energy, temperature, phase can be displated.

– Circuit breaker control function: The status of circuit breaker can be displayed by contact input, and circuit breaker can be controlled by relay output.

– Specification:

• Input: Current 16Ch (200mA,100mV,ZCT output)
• Output: Earth leakage alarm relay 1Ch, communication: RS-485
• Setting: Leakage current sensitivity, buzzer on/off, test, reset.
• Display: Measurement value of leakage current, 16 circuit status, number of displayed circuit.
