Thermal-magnetic circuit breaker RDM5

low-voltageoverloadshort-circuit

RDM5 sériés electronic Moulded case circuit breaker is applied to the circuit of AC 50HZ, insulation voltage 1000V, rated working voltage up to 690V, rated current up to 800A,which to distribute the power and protect the circuit and power source against overload , short-circuit and under voltage damage. Especially, when the current is lower 630A, it also can protect the motor. Normally breaker can infrequently invert and starting of motor. The product can be installed vertically and horizontally.. Normal operating condition and installation condition 1 .Installation location no more than 2000m 2.Temperature: - not higher than +4013,and no lower than -5l3, and the average temperature no higher than +3513 3.The - relative humidity: no more than 50%,when temperature is +40
