The Macromatic GR120A3T general purpose relay has a life of 10,000,000 mechanical operations. If there is no power put on the relay output, it will operate 10,000,000 times before it fails, which is an industry standard performance benchmark. The actual relay output contacts are rated for 10 Amps, so if you switch 10 Amps, the relay would burn out its metal parts after 100,000 electrical operations. As another example, if you only switch 3 Amps of current, it would take about 300,000 electrical operations to burn out its metal components.
