The SD150X is a high-performance, high-current surge protection device (SPD) from Eaton's MTL SD series (Crouse-Hinds series), specifically engineered to safeguard sensitive electronic equipment, control systems, and field instrumentation from damaging voltage transients and lightning-induced surges on higher voltage loops.
With a nominal voltage rating of 150V DC / 120V AC and a high nominal current rating of 3A, the SD150X stands out from standard SD series models by supporting higher-power circuits while maintaining the series' signature ultra-slim DIN-rail form factor. The device features multistage hybrid protection circuitry with a maximum surge current capacity of 20kA.
Certified with ATEX for use in potentially explosive atmospheres (Zone 2), the SD150X is the trusted choice for industrial automation, process control, and instrumentation applications requiring robust, high-current protection.
| Code Segment | Meaning |
|---|---|
| SD | Surge Protection Device (SPD) — MTL SD series |
| 150 | Nominal voltage — 150V DC / 120V AC |
| X | Denotes the high-current variant with increased current handling capability (3A nominal) |
The "X" suffix distinguishes this model from standard SD series models (SD07, SD16, SD32, SD55), which typically handle 400mA, making the SD150X suitable for higher-power circuits.
