RDM1 Series CE CB ISO Moulded Case Circuit 400V or 690V Breaker (MCCB)

RDM1 series product has small volume, high breaking capacity, short arc, anti vibration advantages, whichis the ideal product for land and marine use. Breaker rated insulation voltage 800V (RDM1-63 insulation voltage is 500V), is applied to distribution network of AC 50Hz/ AC60Hz, rated working voltage up to 690V, rated current up to 1250A to distribe the power and protect the circuit and power source against overload, short- circuit and under-voltage damage, and it also can be used to transfer circuit, motor_x005fstart unfrequently and overload, short-circuit and under-voltage protection. The product can be installed vertically and horizontally.

Normal working condition and Installation environment：

1. Temperature: no higher than +40°C, and no lower than -5°C, and the average temperature no higher than +35°C.
2. Installation location no more than 2000m.
3. The relative humidity: no more than 50%, when Temperature is +40°C. The product can withstand the higher humidity under lower temperature, for instance, when temperature at +20°C, the product can withstand 90% relative humidity. The condensation that happened because of temperature changes should be taken care in special measurements
4. Class of pollution : 3 Class
5. Maximum install inclined Angle : 22.5°
6. Auxiliary circuit and control circuit installation type : II Class; Main circuit breaker installation type: III Class;
It can stand the normal vibration and operate stably under marine condition.
