Tips: Can relays replace DC contactors?

Relays generally cannot replace DC contactors in high-voltage or high-current DC circuits.

Current & Voltage: Relays handle low currents and low voltage; DC contactors handle high currents and high voltage safely.
Arcing: DC contactors are designed to extinguish arcs in DC circuits; relays usually are not.
Durability: DC contactors have longer mechanical and electrical life under heavy DC load.
Safety: Using a relay instead of a DC contactor can cause contact welding or failure.
