Rayvoss M
The Raycap Rayvoss® "M" Series is a surge suppression system designed for high-risk and critical power protection applications. It contains Strikesorb® 80 or Strikesorb 40 protection modules and has a higher current capacity than the S series due to its UL-listed installation with 35 mm² (100 A) cable.
The Rayvoss® "M" Series is a complete surge suppression system designed for high-risk and critical power protection applications. It contains Strikesorb® 80 or Strikesorb 40 protection modules, depending on the application's requirements, and is offered with various operating voltage options.
Strikesorb, the high-surge capacity protection element within Rayvoss systems, repeatedly dissipates excess energy from lightning and grid-induced surge impulses without performance degradation or aging. This eliminates the problem of declining protection levels over time, common in conventional systems.
A defining difference in the system's design is that it does not require an internal fuse. Since cables can be connected directly to the internal busbars, voltage drop across a fuse is eliminated, resulting in advantages such as lower clamping voltage, zero maintenance, and no replaceable parts. Rayvoss can also be mounted in-line, which eliminates the need for long cable runs, ensuring the lowest possible clamping voltage.

Rayvoss M is preferred in critical power applications where high current capacity and high surge energy are simultaneously required:
- Main distribution panels — First-stage protection at high-current supply points
- Data centers — Critical power distribution and main supply lines
- Heavy industrial facilities — Production lines with high installed power
- Power generation and distribution facilities — Substations and field distribution points
- Renewable energy plants — AC collection points in solar and wind farms
- Frequency inverters (VFD) and motor control centers — High-power drive panels
- Outdoor installations — Locations requiring external mounting due to NEMA 4 enclosure
- Hospital and critical infrastructure facilities — Systems where interruption directly leads to service loss
