Pepperl+Fuchs 098916 One-Channel Field-Mount Surge Protection Barrier
The Pepperl+Fuchs catalog number for an FS-LB-I stainless-steel surge barrier used at a field-device entry.
Overview
Pepperl+Fuchs 098916 identifies the FS-LB-I one-channel surge protection barrier. It is a screw-in field module for protecting the signal connection of a field device.
The stainless-steel body uses an M20 × 1.5 mounting thread. Manufacturer data lists a 20 kA total discharge current for an 8/20 µs impulse, at least 500 V isolation from earth and suitability for hazardous-area applications.
The exact catalog number matters because the FS-LB-I mechanical thread differs from the NPT and PG variants in the same protection family.
Specifications
Features
Field-entry protection
The screw-in enclosure places surge protection close to the connected instrument rather than only inside the cabinet.
Hazardous-area capability
The manufacturer provides the relevant Ex marking and certificate references for the approved installation.
Fast transient response
Published nominal response is 1 ns symmetrical and 100 ns asymmetrical.
Distinct mechanical code
The M20 thread is part of the FS-LB-I identity and should not be substituted with another F-series thread form.
Applications
Field transmitter protection
Protecting one field signal line where the instrument enclosure provides the matching M20 entry.
Ex-area instrument loops
Using the barrier within the limits and installation conditions of its hazardous-area approvals.
Outdoor junction points
Applying the stainless-steel IP67 field-mount housing in a properly sealed installation.
Lifecycle
Record the mechanical entry
Capture 098916, FS-LB-I marking, thread size, enclosure entry and loop drawing.
Inspect the surge path
Check bonding, cable routing, enclosure sealing and the condition of the stainless-steel body before return to service.
Verify loop integrity
Confirm insulation, continuity, signal quality and the applicable hazardous-area checks after installation.

FAQ
What should accompany a 098916 quotation request?
Send the FS-LB-I label, loop voltage and current, field-device type, M20 entry detail, hazardous-area classification and quantity.
Is 098916 the NPT-thread version of this barrier?
No. Pepperl+Fuchs identifies FS-LB-I as the M20 × 1.5 version; the FN-LB-I uses a 1/2-inch NPT mounting thread.
Which surge ratings belong to 098916?
The published values are 20 kA total discharge current, 10 kA line-to-ground and 5 kA line-to-line for the stated impulse conditions.
What enclosure evidence matters when replacing 098916?
Confirm the M20 entry, thread engagement, seal arrangement, bonding path, ingress protection and hazardous-area installation requirements.
How should 098916 be accepted after installation?
Inspect the mounted seal and bonding, then verify loop continuity, insulation, stable signal transmission and all site-required Ex checks.
