Advantages of SSR over contactor

Zero Voltage Turn-On No contact arcing, low EMI, high surge capability High resistance to shock and vibration High resistance to aggressive chemicals and dust No electromechanical noise Logic compatibility Fast switching Low coupling capacitance Long Life and high reliability more than 1010 cycle operations Increases system temperature accuracy Unique Input & Output LED indication gives heater failure status & increases surge current / voltage capacity.
Limitations of SSR
Contact voltage drop Do not have potential free contacts Do not have multiple contacts in one modules Having Leakage currents Heat sink is must for heat dissipation for current more than 3Amp
