Are general-purpose relays designed for heavy-duty industrial applications?

General-purpose relays are typically not designed for heavy-duty industrial applications. They are intended for use in general control and automation tasks, often handling lower power loads and basic switching functions. Their design prioritizes versatility and cost-effectiveness over the ruggedness and durability required for demanding industrial environments.

In heavy-duty industrial applications, specialized relays such as contactors or heavy-duty relays are preferred because they can handle higher voltages and currents, have better insulation and heat dissipation capabilities, and have a longer lifespan under challenging conditions. General-purpose relays may not provide the reliability, safety, and robustness needed in such situations, which is why they are not suited for industrial heavy-duty tasks.

Thus, stating that general-purpose relays are not designed for heavy-duty applications is accurate.
