The Surge Protection Device (SPD) - Electrical Installation
WEBThe Surge Protection Device (SPD) is a component of the electrical installation protection system. This device is connected in parallel on the power supply circuit of the loads that it has to protect (see Fig. J17). It can also be used at all levels of the power supply network.
What is a Surge Protection Device? – Principle, Types, Advantages
WEBA surge protection device (SPD) is connected in parallel with the load. The input supply is given to the load through the circuit breaker, and it is also given to the SPD in parallel. The main part that stands out is the ground or earth connection.
