Can A Relay Get Weak at Savannah Mackerras blog

Can A Relay Get Weak. Relays that are used frequently can experience mechanical wear and tear, which can cause the contacts to wear out or the actuator to fail. Relays can fail because of a number issues, find some information on common failure. In many cases, an extremely high voltage spike may cause instant failure due to an arc between coil and contacts, or between sets of contacts. Below, i’ve highlighted the most common signs of a bad main relay. The easiest way to test a relay is to swap it out with a known good replacement, but this can be disadvantageous if the same problem that cooked the first relay can occur again. Heat is a common enemy. The good news is that if you suspect a bad main relay, it’s pretty easy to rule out, and it’s cheap to replace. A relay may fail if it is exposed to excessive current or voltage, which can burn out the contacts or damage the coil. Contactor armatures often get dirty and can't pull in fully, resulting in continous higher currents, generating heat, which in turn distort coils, causing. This may happen in either. What causes relays to fail.
