Type 1 Surge Protector Device

The T1SPD is an easy to install surge protector that meets all applicable electric codes. It is used for 120/240 electrical services and can be used in pairs for 240 V Delta 3 phase and 120/208 Wye 3 phase services. The T1SPD is rated to handle surges 25% higher than the average lightning strike so it will work reliably for years. The T1SPD design prevents failure due to open neutrals or other system disturbances. The T1SPD is compact and includes an LED indicator to show that it is working.
