What do direct current starters and contactors that do not utilize arc suppressors or magnetic blowout coils use to break the circuit?
What will be an ideal response?
Direct current starters and contactors that do not utilize arc suppressors or magnetic blowout coils often use multiple contacts to break the circuit. Connecting contacts in series gives the contactor the ability to break higher voltages
