Key Points

FAQ

How does the plug-in series differ from fixed versions?

Both types share the same T2 class electrical parameters, but plug-in modules sit on a base and are swapped out for replacement, while fixed versions are removed and reinstalled as a whole unit.

Which protection modes are supported?

Six protection modes are supported: 1P, 2P, 3P, 4P, 1+NPE and 3+NPE. The same series is rated T2 class with In 20kA, Imax 40kA, Up 1.5kV/1.8kV and response time ≤50ns.

What is the selectable Uc range for the series?

Uc is selectable in multiple steps from 275V to 760V. The step is chosen according to the voltage of the distribution system.

What are the installation requirements?

Mounting is on a standard 35mm rail inside a distribution cabinet or enclosure, with protection degree IP20. Modules plug into the base.

How is the product certified and quoted?

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