Relay contact life

Relay contact life


The service life of a relay depends on its contacts. 

After the contacts are burnt, the relay contacts or the entire relay must be replaced. 


Mechanical life refers to the number of operations (opening and closing) that a contact can perform without current. The mechanical life of the relay is relatively long, providing 1,000,000 operations. 


The electrical life of a relay refers to the number of operations (opening and closing) that the contact can perform with current under a given rated current. Normally, MEISHUO'S relay could provide contact electrical life rating 100,000 cycles.
