ELECTRICAL LIFE Electrical life tabulated below is B₁₀ value in a single test (at the condition shown in IEC 62246-1-1)at Yaskawa. It is not a value in a multiple environment such as temperature and vibration. It is necessary to test actual products before initial operation. The circuit that drives coils adopts a direct making method which applies rated coil voltage(instant ON and instant OFF). In the circuit where the voltage applied to coils gradually increases or decreases, electrical life might decrease. Also, in the circuit where exceeded the rated operating voltage and current of contacts,...
