Residual Current Circuit Breaker SPM1L

1. Brief Introduction of Residual Current Circuit Breaker SPM1L:
The rated insulated voltage of residual current circuit breaker with residual current protection SPM1L is 800V, suitable for infrequently transfer or engine infrequently start-up under such conditions: AC of 50Hz, a voltage less 400V and a rated working current up to 1600A.The circuit breaker that protects over voltage, short-circuit and under voltage has other functions such as residual current alarm, protection and communications. Furthermore, they can also be used as residual current fire monitors. Installation modes of the circuit breaker can be vertical or horizontal. The circuit breakers have isolation function, but can not filled lines in reversed direction.

2. Perform Standards of Residual Current Circuit Breaker:
The products meet IEC 60947-1 and General GB 14048.1-2000
general rules IEC 60947-2 and GB14048.2-2001
low-voltage circuit breakers IEC 60947-4-1 and GB14048.4-2003
Electromechanical Contactor and Motor
Starter

3. Working Conditions of Residual Current Circuit Breaker:
Ambient temperature should neither exceed +40 ℃ nor under -5 ℃, keep the average temperature not more than +35 ℃ within 24 h.
The elevation can not exceed 2000 m.
The surrounding relative humidity at the highest temperature of +40 ℃ should keep less than 50%, a lower temperature can form a higher relative humidity, for example, 20 ℃ versus 90%. Occasionally dew caused by the temperature change should be cleared off.
Cause pollution of third grade.
The installation category of the main circuit breaker and voltage release is Ⅲ; and the installation category of control circuit and other auxiliary circuit isⅡ.
Moist tropical type of circuit breakers can endure the impact of hot and humid weather, salt mist and leaf mold.
The circuit breakers should be installed in the places of no hazardous explosive devices, no conductive dust, no metal corrosion and no insulation damage.
The circuit breakers should be installed in the places without attack of rain and snow.

4. Characteristics of Residual Current Circuit Breaker:
Adjustable long time delay period and residual current protection.
Residual current protection needs no auxiliary power and directly from three-phase power of independent circuit.
Low-voltage protection: When the voltage lowered to 50 V, leakage protection module can still work
Real-time Monitoring: The intelligent monitoring of residual current can display the residual current volume on LCD. With rating residual action-current and the longest break time clearly and canonically, it has the functions of pre-alarm and residual current alarm with no disengaging, and has a memory of fault, can store the last residual current fault information.
The communication module upload the volume of residual current, fault information, disengaging information and status information real-time to meet the requirements of electrical fire control system.
The residual current circuit breaker accords with EU environmental directions.
Powerful function of expansion: can add residual current alarming module, and implement the function of current alarm with disengaging and current alarm without disengaging.
