What is the difference between electrical life and mechanical life in relays?
Mechanical life is to ensure that the relay is not due to internal mechanical back and forth action wear and tear deformation caused by damage time.
Electrical life is to ensure that the relay is not due to contact ablation, coil blown, insulation aging caused damage time.
Mechanical life: coil plus rated voltage, contact unreasonable load. The role of mechanical life is to examine the durability of relay materials fatigue. Generally more than 10 million times.
Electrical life: coil plus rated voltage, contact with rated load. The purpose of electrical life is to examine the practical application of the relay load capacity. Generally more than 100,000 times.
Mechanical life is to ensure that the relay is not due to internal mechanical back and forth action caused by the dynamic spring or which part of the operation because of repeated damage time. Mostly bending part of the spring.
Electrical life is to ensure that the relay is not due to contact ablation, coil blown, insulation aging caused damage time.
? Under normal circumstances the mechanical life can be achieved, but the contact load is that electrical life is rarely achieved.
