DEHNSPD Check
Our launch hypothesis

IEC first. Keep the entry simple.

For this market test, the Finder organises products by IEC application and SPD class. It is an orientation tool, not a final design or compliance decision.

IEC 61643-11

Surge protective devices for low-voltage AC power systems — including Type 1, Type 2 and Type 3 product classes.

IEC 61643-31

Requirements and test methods for SPDs used on the DC side of photovoltaic installations.

IEC 61643-41 / IEC 61643-21

Orientation for DC power systems and protection of telecommunications and signalling networks.

The exact product still needs to match voltage, network configuration, prospective short-circuit conditions, installation concept and local availability.

What the Finder gives you

A product shortlist — not another technical exam.

Users can start with the application they already know. The result presents product families worth comparing and a compact list of details to confirm before ordering.

1

Relevant family first

Lead with the most broadly relevant DEHN family for the selected application.

2

Useful alternatives

Show combined, prewired or application-specific product families where they may fit.

3

Final variant check

Confirm network, voltage, ratings, coordination and Australian availability before ordering.

Before ordering

Category match first. Exact variant next.

The SPD Finder deliberately stops at product-family level. The final device and configuration must be checked against the electrical system, manufacturer instructions, applicable requirements and products available for the Australian market.
