Product Description:

Application
DZ47L C45L RCBO is used for the protection against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage 1 phase 230V and 3 phase 400V, rated current up to 63A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the RCBO can cut off the power within the time of 0.1s automatically to protect the personal safety and preventing the equipment from the fault resulted by the residual current. With this function, the RCBO can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions. It conforms to IEC61009 standard.
Normal Operation and Mounting Requirement
◆Circumstance temperature -5~+40, average temperature not exceeding 35.
◆Altitude above sea level less than 2000m.
◆Humidity not exceeding 50% at 40 and not exceeding 90% at 25.
◆Installation class II or III.
◆Pollution class II.
◆Installation method DIN Rail mounting type.
◆The external magnetism shall not be more than 5 times of terrestrial one.
◆Product shall be installed vertically at the place where there shall be no severe impact and vibration. The product is switched on when the handle is at upper position.

Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
in the maintenance as a clear point, and can not carry sub-gate, or will pull the arc ACCIDENT.
Q:Circuit system diagram and circuit breaker connection
Isolation switch only play a role in isolation, the back of the circuit is not automatically broken off,
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
measuring and monitoring instruments, relays, automatic devices, etc. through the control cable into the circuit.
Q:What is the solution of the leakage circuit breaker always jumping?
if it exceeds its rated current or leakage, primarily for home or office lighting and to ensure the safety of the person.
Q:Why the high-voltage circuit is equipped with isolation switch and circuit breaker
So the isolation switch installed in front of the circuit breaker, open, so that between the power supply and the circuit breaker has a clear point
Q:Load switch, vacuum switch and circuit breaker
Load switch: can safely cut off the load current, can not cut off the short circuit current
Q:What is the capacity of the circuit breaker
The breaking capacity of the high-voltage circuit breaker is the same as that of the rated breaking current
Q:Is this an air switch or a leak protector?
The second with overload protection. Short circuit protection and leakage protection of the RCD. Also known as leakage circuit breaker.
Q:Does the isolator and circuit breaker able to switch to each other?
When the circuit breaker disconnect the live circuit, the internal contact in the separation of the moment will produce an arc, the higher the voltage or the greater the current, the stronger the arc.
Q:How to distinguish between disconnectors, circuit breakers?
It is a no arc device switch device
