Selecting DC Contactors for Solar and DC Power Systems

Solar and DC power systems use switching components to control connections between generation, conversion, storage and distribution equipment. A DC contactor should be matched to the voltage range, load current and switching duty of the specific circuit.

Selection should account for steady-state and transient conditions, control voltage, heat dissipation, mounting constraints and the protection strategy used in the system. Electrical validation should be completed in the final equipment design.
