What is one advantage of using an electromechanical relay over a solid-state relay?

One significant advantage of using an electromechanical relay over a solid-state relay is its ability to stand surge currents. Electromechanical relays are constructed with physical contacts that can handle high inrush currents without damage. This mechanical characteristic allows them to withstand brief surges that may occur in electrical circuits, which is particularly important in applications where inductive loads, such as motors or transformers, are involved.

The mechanical design of these relays provides a physical buffering effect that can absorb and mitigate sudden increases in current, which is critical for protecting the downstream components in the circuit. While solid-state relays have their own set of benefits, including faster response times and lower power consumption, they can be more vulnerable to damage from high surge currents due to their electronic components, which lack the physical resilience of mechanical contacts.
