Strikesorb Series

Strikesorb 30-DRM

Raycap Strikesorb® 30-DRM is an industrial Surge Protective Device (SPD) offering Strikesorb technology in a DIN rail-mounted enclosure. It provides quick installation into standard panels, along with fuse-free direct connection and maintenance-free operation for uninterrupted protection.

Strikesorb® 30-DRM is a DIN rail-mounted surge protective device (SPD) designed for critical facility protection against lightning and grid-sourced overvoltage surges. Classified under IEC 61643-11, the product is also fully recognized under UL 1449 5th Edition. Its DIN rail compatibility allows direct installation into standard distribution panels without requiring special housing or mounting solutions.

The fundamental difference of Strikesorb technology is its continuous protection operation. While classic varistor-based devices degrade with successive surges and lose their protective capability over time, the Strikesorb 30-DRM dissipates high-energy surges without module degradation. Its fuse-free direct connection eliminates additional components and associated failure points in the protection path. The low let-through voltage ensures optimal protection for connected equipment.

The device is designed without flammable, smoke-emitting, or explosive materials, and its fully sealed enclosure ensures reliable operation in harsh conditions. It is tested and certified according to international IEC and UL safety and performance standards. Based on years of field performance data, its expected service life exceeds 20 years, and all modules come with a 10-year limited lifetime warranty.

Strikesorb 30-DRM is preferred in applications where Strikesorb protection performance is desired within standard panel infrastructure:

Standard distribution panels — Direct mounting into existing DIN rail panel structures
Sub-distribution panels and floor panels — Second stage of cascaded protection
Machine and automation panels — Production line supply points
Industrial facilities — Cases requiring subsequent protection addition to existing panels
Telecommunication and field cabinets — Compact in-panel solutions
Commercial buildings and facility management applications — Systems requiring easy installation and maintenance-free operation
Renovation and modernization projects — Increasing protection level without panel modification
