Rayvoss A
The Raycap Rayvoss® "A" Series is the highest current capacity surge suppression system in the Rayvoss family. Featuring Strikesorb® 80 protection modules, it is designed for high-power main service entrances with UL-listed installation using 120 mm² (225 A) cable.
The Rayvoss® "A" Series is a complete surge suppression system designed for high-risk and critical power protection applications. It features Strikesorb® 80 modules, the highest capacity protection element in the series, and is available with various operating voltage options. UL-listed installation with 120 mm² (225 A) cable makes the A series the highest current member of the Rayvoss family.
Strikesorb, the high-surge capacity protection element within Rayvoss systems, repeatedly dissipates excess energy from lightning and grid-induced surges without performance degradation or aging of the SPD module. This eliminates the problem of protection level decline over time common in classic systems.
A key design difference of the system is its lack of internal fuses. Cables can be connected directly to internal busbars, eliminating voltage drop across a fuse. This results in advantages such as lower clamping voltage, zero maintenance, and no replaceable parts. Rayvoss can also be installed in-line, which eliminates the need for long cable runs, ensuring the lowest possible clamping voltage.

Rayvoss A is preferred for high-current main service entrances and applications where the highest surge energy is expected:
- High-power main distribution panels — Highest current capacity solution in the series
- Power generation and distribution facilities — Substations and transformer stations
- Heavy industrial facilities — Production lines with high installed power
- Data centers — Main service and critical power distribution
- Renewable energy plants — AC collection points in solar and wind farms
- Large-scale commercial and industrial facilities — Building entrance point protection
- Outdoor installations — Locations requiring external mounting due to NEMA 4 enclosure
- Hospital and critical infrastructure facilities — Systems where interruption directly leads to service loss
