Product Q&A

Q:What is the response time of this surge protector?

The device features a fast response time of less than 25 nanoseconds due to its high-efficiency varistor nano-alloy graphite material.

Q:How does the failure release mechanism work?

When the protector overheats or breaks down, the failure release device automatically disconnects it from the grid. A red window signal indicates failure, requiring immediate replacement.

Q:What remote monitoring features are included?

It includes remote communication alarm contacts (normally open and normally closed). When a module fails, the dry contact state changes to alert users.

Q:What are the electrical specifications?

Key specs include: Max continuous operating voltage of 420V, nominal discharge current of 10kA, max discharge current of 20kA, and protection level of 1.8kV.

Q:Is this device suitable for all power systems?

Yes, it is suitable for TT, IT, TN, and other power supply systems, specifically designed for T2 protection in AC/DC systems.
