Tercel Zeus Series — Technical Specs
The Tercel Zeus product lineup (which includes these TZ- series models) provides detailed performance specs:
| Model | Trigger Gain (ΔT) | Weight | Protection ΔL (meters) | Notes |
|---|---|---|---|---|
| TZ-20 | 20 μs | 3.5 kg | 20 m | Stainless Steel, NFC17-102 |
| TZ-40 | 40 μs | 3.8 kg | 40 m | — |
| TZ-50 | 50 μs | 3.5 kg | 50 m | — |
| TZ-63 | 63 μs | 4.0 kg | 63 m | — |
| TZ-90 | 90 μs | 4.5 kg | 90 m | — |
-
All models meet standard NFC17-102, have current capacity ≥200 kA (10/350 μs), and withstand winds ≥40 m/s.
-
Note: The protection radius (ΔL) is not an absolute radius but a gain in triggering time converted into additional protection distance. For reference, the TZ-63 (like earlier models) offers up to ~110 m radius when mounted at 5 m above terrace.

- Lead times, minimum order quantities, and installation support.
- Compliance documentation (e.g., CPRI or other testing).
-
Evaluate which model suits your needs:
- For higher protection distance, go with TZ-63 or TZ-90.
- For compact rooftops, TZ-20 or TZ-40 may suffice still offering active streamer emission benefits.
-
Confirm performance needs based on building height, local lightning incidence, and asset sensitivity.
