Pepperl+Fuchs K-LB-2.30G Grounded Surge Protection Barrier

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.

Product Overview
2-channel design for mounting on DIN rail
For intrinsically safe or non-intrinsically safe 30V applications
Protects field or control circuit inputs
Max. surge current (8/20 µs) 20 kA
Uninterruptable operation with auto reset
SIL 3 certified per IEC/EN 61508
Key Features & Benefits
FeatureBenefit
Grounded TopologySpecifically 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 TransparentInsertion loss ≤0.05 dB (0-4 kHz, 600Ω system) — seamless HART communication with no signal degradation
SIL 3 CertifiedCertified 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 LevelClamps line-line to ≤100 V and line-earth to ≤50 V @ nominal discharge current — protects sensitive I/O cards

Applications
  • Process Industries: Protection of PLC/DCS I/O cards in chemical and pharmaceutical plants
  • Oil & Gas: Field circuits in hazardous areas requiring intrinsic safety (Ex ia IIC)
  • Power Generation: Vibration monitoring, thermocouple, and RTD measurements
  • Water/Wastewater: SCADA systems, flow metering, and remote telemetry units (RTUs)
  • Safety Systems: Emergency shutdown (ESD) and fire & gas detection systems requiring SIL 3
Installation Note: Always connect the device to high-quality ground connections. The device must have the same potential as the devices it protects. Install the ground system in accordance with applicable regulations.
K-LB-2.30G vs. K-LB-2.30: Which One Do You Need?
FeatureK-LB-2.30G (Grounded)K-LB-2.30 (Non-Grounded)
TopologyGrounded (common ground)Floating / Isolated
Best ForSystems where signal shares ground with protectionIsolated systems, floating signal loops
Part Number098913098909
Line-Earth Protection Level≤50 V≤1.2 kV
ApplicationCommon-ground installationsGalvanically isolated systems
Selection Guide

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.

Why Choose the K-LB-2.30G?

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.
