FAQ

Which models are available in the T2-ZL(S) range?

The range includes ZL2-V-x/275-4P, ZLS2-V-x/385-4P, ZL2-V-x/275-2P and ZLS2-V-x/385-2P. They combine Uc of 275V or 385V with 2P or 4P pole configurations.

What is the surge current capability of the range?

Nominal discharge current In spans 10kA to 40kA and maximum discharge current Imax spans 20kA to 100kA. The exact figure depends on the model and on the test conditions.

What are the Up and response time values?

Up is 1.5kV when Uc is 275V and 1.8kV when Uc is 385V. Response time is ≤50ns across the series, with local failure indication on the device.

What is the difference between S and non-S models?

ZLS2 models carry remote signalling and can report a failure signal remotely, while ZL2 models only provide the local failure indication window.

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 for the model and quantity needed.
