RAJA62 RTP SLOT Contacts can be produced from a wide variety of materials. Contacts are rated for the current carrying capacity while closed, breaking capacity when opening (due to arcing) and voltage rating. Opening voltage rating may be an AC voltage rating, DC voltage rating or both. When relay contacts open to interrupt a high current with an inductive load, a voltage spike will result, striking an arc across the contacts.|Pretend you're Looking for a Folder
