RMM1L series residual current circuit breaker
Scope

RMM1L Series
Residual current protection circuit breakers rated insulation voltage 690V, mainly applied to AC 50HZ, rated voltage 400V, rated current up to 800A circuit as frequent conversion and motor starting frequent start with.
The remaining short-circuit breaker with overload, short circuit and under-voltage protection function, can protect the circuit and power supply equipment from damage and also may cause long-term ground fault overcurrent protection can not be detected
The risk of fire protection. The conventional current protection circuit breaker leakage protection module power sampling for two groups, this series circuit breaker for the three groups, one phase circuit breaker leakage protection module to work properly,
Rated residual operating current is adjustable with leakage alarm output function.
Normal use, installation and transport conditions
Normal conditions of use
1, the ambient temperature: the upper limit does not exceed +40 ℃, the lower limit is not lower than -5 ° C, the average temperature values ​​within 24h does not exceed +35 ° C;
Note: in the ambient air humidity is higher than +40 ° C or below -5 ℃ under the conditions of use residual current circuit breaker should be in consultation with the manufacturer;
Altitude: average altitude does not exceed 2000m;
3, atmospheric conditions: +40 ℃ maximum temperature does not exceed 50%, higher relative humidity at lower temperatures, the wettest month of the average maximum relative humidity not more than 90%, while the average minimum temperature for the month +25 ℃, and considering the temperature change occurs
Condensation on the surface of the product;
4, in no danger of explosion in the media environment, and media without enough to corrode metal and destroy the insulation of gas and charged dust.
Normal conditions
1, installed in the shock and vibration, and rain and snow, on terminals connected to the supply side, under the wiring terminal connected to the load side, with the direction of the measured slope of no more than 5 degrees;
2, the pollution level: 3;
3, the main circuit of the installation category III, is not connected to the main circuit of the auxiliary circuits and control circuits, installation category II;
4, the residual current circuit breaker installation place attachment external magnetic field, the magnetic field in any direction should not be more than 5 times.
Normal storage and transport conditions
1, the temperature of the lower limit of not less than -25 ℃, the upper limit of not more than +50 ° C;
2, relative humidity (25 ℃ pm) does not exceed 95%;
3, the product during transport, it should be light to move gently and should not be upside down, should avoid the violent collision.
  
(MBM1L) CM1L leakage molded case circuit breaker, is suitable for use in ac 50 Hz ac (or 60 Hz), the rated voltage is 800 V insulation, rated voltage 400 V, rated current to 630 A (800 A) circuit for not frequent changeover and motor starting with less frequent. Circuit breaker with overload, short circuit and owe voltage protection function, and can protect the power lines and sustainable damaged; At the same time, can provide indirect contact with protection of people, can also across the current protection department can detect the long-term existence of the ground fault may cause the fire danger for protection. In other protection device failure, rated surplus operating current for 30 the mA's MYM1L leakage circuit breaker can be directly up additional protection.
