Product life of relay output contacts
The product life of relay output contacts varies considerably depending on the load type used.
Note that loads generating reverse electromotive force or rush current may cause poor contact or welding of contacts which
may lead to considerable reduction of the contact product life.
■ Inductive load
Inductive loads generate large reverse electromotive force between contacts at shutdown, which may cause arc discharge. At
a fixed current consumption, as the power factor (phase between current and voltage) gets smaller, the arc energy gets larger.
The following table shows the standard life of contacts used for inductive loads, such as contactors and solenoid valves.
The following table shows the approximate life of a relay based on the results of an operation life test.
• Test condition: 1 sec. ON/1 sec. OFF
The product life of relay contacts becomes considerably shorter than the above conditions when the rush overcurrent is shut
down.
Please refer to the following measures regarding the inductive load.
 Page 101 Contact protection circuit for inductive loads
Some types of inductive loads generate rush current 5 to 15 times the stationary current at activation. Make sure that the rush
current does not exceed the current corresponding to the maximum specified resistance load.
■ Lamp load
Lamp loads generally generate rush current 10 to 15 times the stationary current. Make sure that the rush current does not
exceed the current corresponding to the maximum specified resistance load.
