208V/120V (3P4W) Three Phase Wye Surge Protector SP3P208VY

208V Three Phase Wye Surge Protector 3P4W (SP3P208VY)

Most 208V power systems are a Wye configuration because

• Phase to neutral voltage is 120V
• Phase to phase voltage is 208V

A 208 3 Phase Wye power system is called 208V 3 Phase 4 Wire and 208Y/120V. These are technically more accurate because they refer to the neutral.

• The “4 Wire” in 208V 3 Phase 4 Wire refers to the neutral as 4th wire.
• The” Y” in 208Y/120V refers to the neutral as the center of the Y shaped power source.

Green LED status indicator for each phase provides fast verification of operation. Designed for indoor or outdoor use and includes 36 inches of wire and a waterproof 3/4" liquid tight style conduit connector.
