Safety Precautions
- Install on flame-retardant materials such as metal.
- Do not install in environments containing explosive gases, otherwise there is a risk of explosion.
- Do not install in damp places.
- Do not operate the circuit breaker with wet hands, otherwise electric shock may occur.
- Do not install where external magnetic field is greater than the Earth's magnetic field, otherwise the circuit breaker will not work properly.
- Do not install where vibration exceeds 5G.
- Do not install where the gas medium can corrode metals and damage insulation.
- Maintenance and inspection must be performed by professional technicians.
Operation Guide
1: Pre-operation Inspection and Preparation
Before operation, check the following items:
- Check that wiring is correct, especially that the input terminals (1, 3, 5) of the circuit breaker should be connected to the power line, and the output terminals (2, 4, 6) should be connected to the load line.
- Confirm that there is no short circuit or ground fault between terminals or exposed live parts.
- Confirm that terminal connections and fixing screws are tight and not loose.
- If the circuit breaker is equipped with an undervoltage trip unit, the trip unit should be energized first before the circuit breaker is allowed to close.
2: Trial Operation
After confirming all items are normal, trial operation can be performed:
- Adjust Ir1, Ir2, I2, Ir3, Ir0 on the front cover as needed by the user.
- Switch the operating handle to apply power (must meet condition 1.4 above).
- After the main circuit of the circuit breaker is energized, press the trip button. The circuit breaker should trip, and the operating handle should be in the tripped position.
3: Operation
If step 2 is satisfied, operation can proceed according to step 2.2.
