Hi,
Why switching the DC side, why not the AC side.
Switching elements are specified by voltage and current (power relays additionally give some motor power information)
Current causes heat
Voltage causes arcing
An opening switch in combination with series inductance will cause high voltage spikes and adrcing. On AC systems the arc will be extinguished in the zero crossing if current. DC does not have a zero cross, thus it does not self-extinguish an arc. Thus DC is more difficult to seitch OFF and thus the DC voltage rating usually is lower than the AC voltage rating.
What switching device you want to use is your decision:
There are ready to buy mechanical relays, there are triac based and MOSFET electronic relays (soloid state relays).
Triac based are for AC only.
And you may design your own electronic switch.
Which one to chose depends on your requirements. Besides I and V, switching count, frequency, zero cross switching or not ...
But also: cost, size, power dissipation, ruggedness, overvoltage protection, control power, humidity, dirt, safety level, isolation or not, ....
The simplest way maybe is a low side logic level MOSFET...
But as said: It depends on your requirements.
