Pepperl+Fuchs K-LB-2.30 | 2-Channel Surge Protection Barrier 24V DC 20kA SIL 3 Intrinsically Safe

Product Overview

PEPPERL+FUCHS Surge Protection Barrier K-LB-2.30

This 2-channel surge protection barrier mounts on DIN rail and is designed for intrinsically safe or non-intrinsically safe 30V applications. It protects field or control circuit inputs with maximum surge current (8/20 µs) of 20 kA and features uninterruptable operation with auto reset. Certified up to SIL 3 according to IEC/EN 61508.

Function & Operation

The device limits induced transients from various sources such as lightning or switching operations. Current is diverted to earth while limiting signal loop voltage during overvoltage pulses. The device is HART transparent and mounts on 35 mm DIN mounting rail according to EN 60715.

Important: Always connect to high-quality ground connections. The device must maintain the same potential as protected devices. Install ground system according to applicable regulations.

Industrial Surge Protection for Signal Loops

The Pepperl+Fuchs K-LB-2.30 is a high-performance surge protection barrier designed to safeguard signal circuits from damaging transients caused by lightning strikes and switching operations. As part of the K-System, this module provides reliable overvoltage limitation for both intrinsically safe and non-intrinsically safe 30V applications.

Key Features & Benefits

Robust 20kA Surge Capacity: Handles total discharge current of 20 kA (8/20 µs) and impulse currents up to 10 kA per line
Uninterruptable Operation (Auto Reset): Automatically resets after surge events, eliminating manual replacement
HART Transparency: Extremely low insertion loss (<0.05 dB at 4 kHz) for seamless HART communication
Functional Safety (SIL 3): Certified up to SIL 3 according to IEC/EN 61508 for safety-instrumented systems
Hazardous Area Ready: ATEX/IECEx certified for Ex ia IIC T6/T5/T4 and Zone 2 applications

Why Choose the K-LB-2.30?

Unlike standard surge protectors, the K-LB-2.30 is specifically engineered for 4-20 mA loops. It provides a "fit and forget" solution with auto-reset technology, ensuring your process remains online without interruption. Its ultra-slim 12.5 mm housing saves valuable cabinet space while providing world-class certification for global use (IECEx, ATEX, CSA, CCC Ex).
