Replaceable Surge Protector Wiring, Installation & Connection Guide
The LT-80RT / LT-100RT SPD is wired with the protection circuit and grounded via the PE terminal. The connection leads should be of minimal length so that the residual voltage can be kept to a minimum value. For TN systems, it is important to connect the L, N and PE terminals according to the wiring diagram that has been provided.
- Parameters for connection via the PE terminal
- External disconnector should be used according to the specification
- Wiring diagram has been provided along with the product
Wiring Diagram
The above connection layout provides a recommended connection for the LT-80RT / LT-100RT in a regular distribution panel, with L, N, and PE points designated per typical standards.
How Does Replaceable Surge Protector Compare to Alternative Protection?
Select the SPD considering the type of the device and its discharge capacity rating as well as voltage rating. Type 3 devices protect terminal equipment, Type 2 devices, protect distribution therewith Type 1 discharges lightning current at the source.
