Key Points

FAQ

What is the difference between split and integrated types?

In the split type the SPD module separates from the base, so the base keeps its wiring when a module is replaced, while the integrated type is replaced as a whole unit. Models, Iimp and Up ratings are consistent between the two.

How do the models correspond to protection class?

All six models are T1 class with Iimp from 12.5kA to 25kA and Up from 1.5kV to 2.5kV. They cover varistor, spark gap and combined structures.

Must the circuit be de-energised before a module is replaced?

The circuit must still be isolated and proved dead according to procedure before a module is replaced. The pluggable structure only reduces the work of disconnecting and reconnecting conductors.

What are the mounting and dimension figures?

Mounting is on a standard 35mm rail. Dimensions are 72×83×88mm for the 4P model and 36×83×88mm for the 2P model, and the figures vary by model within the series.

How is the product certified and quoted?

Certification is CE / CMA / CNAS accredited laboratory for the series. Price and lead time are quoted per project; Request a quote with the model and quantity required.
