2. Not overloaded, but Inrush current from capacitive load welds relay contacts at 〝 ON〞 , resulting in permanent ON, or burns transistor or TRIAC, resulting in permanent ON or OFF. 3. Not overloaded, but the inductive load without proper Snubber circuit causes high voltage sparks between relay contact at〝OFF〞and generate carbon deposition, which separates contacts and causes permanent OFF or intermittent ON/OFF, or punches through transistor or TRIAC with high voltage, resulting in permanent ON or OFF.
