Product Purpose:
1.Personnal and fire protection cable and line protection against overload and short-circuits
2,General rules for choosing RCBO:
A. Rated residual operating current
l^n≤30mA:additional protection in the case of direct contact
l^n≤300mA:preventative fire protection in the case of ground fault currents
B. Tripping class
Meba Earth Leakage Circuit Breakers MBR416C
Application:
1.This is belong to 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.
2.When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time.
3.It is automatically to protect the personal safety and preventing the equipment from the fault resulted by the residual current.
4.With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions.
5.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.
Performance & Usage
Circuit breaker is mainly suitable for overload and short protection. It is especially used for illumination and distribution. It is of pleasing out-look, light weight, reliable performance, high breaking capacity, quick trip. etc.
