Different Methods Of Connecting An Spd To An Electrical
Tvss wiring diagram. The tvss is rated in jouleswattseconds. Wiring lead length between the electrical equipment and the suppressor as short as possible. Addition of four types of spds to cover surge arrestors tvss surge strips and component spds. The multi 9 surge protective device spd also referred to as transient voltage surge suppressor tvss manufactured by square d provides high quality surge protection for electronic equipment. Series tvss can be used in industrial medical and commercial applications. The surgelogic eba series surge protective device is a non modular parallel transient voltage surge suppressor tvss.
The eba device has multi stage suppression circuits consisting of field proven fast acting metal oxide varistors movs. Tvss will now be referred to as spd surge protective devices. If your voltage spike produces joules integral from 0 to t in seconds of current x volts x dt of energy which is less than 160 joules then the specified tvss is adequate. These devices can be mounted on a 35 mm rail on the load side of the incoming power to protect from transient voltage surges. Ul 1449 is now ansiul 1449. A surge suppression path is provided for each mode line to neutral ln line to line ll line to.
As such eaton was the first.
