2-Channel 30V DC, 20kA, SIL 3, ATEX Ex ia IIC
The Pepperl+Fuchs K-LB-2.30G is a high-performance surge protection barrier specifically designed for grounded (common ground) systems. Part of the proven K-System, this 2-channel module safeguards 4-wire signal circuits from damaging transients caused by lightning strikes and switching operations.
| Feature | Benefit |
|---|---|
| Grounded Topology | Specifically designed for common-ground systems, ensuring proper surge current diversion to earth |
| 20kA Surge Capacity (8/20 µs) | Handles total discharge current of 20 kA, protecting against direct and indirect lightning strikes |
| Uninterruptible Operation (Auto Reset) | Automatically resets after surge events — no manual replacement, zero system downtime |
| Ultra-Low Series Resistance (<0.5 Ω per line) | Minimizes voltage drop in 4-20 mA loops, preserving signal integrity for critical measurements |
| HART Transparent | Insertion loss ≤0.05 dB (0-4 kHz, 600Ω system) — seamless HART communication with no signal degradation |
| SIL 3 Certified | Certified up to SIL 3 according to IEC/EN 61508 for safety-instrumented systems (SIS) |
| Fast Response (<30 ns protection, <30 ms reset) | Responds to transients in nanoseconds; recovers in milliseconds for continuous protection |
| Low Voltage Protection Level | Clamps line-line to ≤100 V and line-earth to ≤50 V @ nominal discharge current — protects sensitive I/O cards |

Choose K-LB-2.30G when: Your signal loop shares a common ground with the control system or you need lower line-earth clamping voltage.
Choose K-LB-2.30 when: Your system uses isolated/ungrounded signal loops.
The Pepperl+Fuchs K-LB-2.30G delivers uncompromising surge protection for grounded signal loops in hazardous and non-hazardous areas. With 20kA surge capacity, SIL 3 functional safety certification, and ATEX Ex ia IIC approval for explosive gas atmospheres, this module is the trusted choice for critical process applications. Its auto-reset technology ensures continuous operation without maintenance, while the ultra-slim 12.5mm housing maximizes cabinet density. Backed by global certifications (IECEx, ATEX, CSA, CCC Ex), the K-LB-2.30G is ready for installation worldwide.
