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:Is the zero line going through the circuit breaker?
220V single-phase line, the zero line through the circuit breaker, because the single-phase line wiring staff complex, chaotic, many times can not tell the line of fire, zero line, so the two have to go through the circuit breaker to avoid electric shock accidents.
Q:Circuit breaker auxiliary contact is what?
to prevent short-circuit, to ensure that the arc up to ensure that contact Reliable breaking of the system. The frame circuit breaker adopts the modular structure,
Q:What is the solution of the leakage circuit breaker always jumping?
The difference between the two is that the air switch will move if it exceeds its rated current and the leakage switch will trip if it exceeds its rated current or leakage
Q:Why the high-voltage circuit is equipped with isolation switch and circuit breaker
The high voltage isolating switch is designed to be able to secure a safe disconnect from the power point when the circuit breaker is overhauled
Q:How is the circuit breaker connected to the circuit system diagram?
Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device; can not disconnect the load current and short circuit current
Q:The difference between air switch and circuit breaker
The air circuit breaker is a switchgear with a variety of protection functions that can cut and turn on the circuit at rated voltage and rated operating current conditions.
Q:Is it possible to switch the lamp directly with a circuit breaker?
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection, when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch
Q:What type of switch circuit breaker has undervoltage protection
hat its trip in the form of double, that is, a thermal release and Electromagnetic release, it has over-voltage, under voltage protection
Q:What circuit symbols are used for circuit breakers
Residual current protection device (hereinafter referred to as the NLD), which detects the residual current,
