Linear 2500-1944, Suppressor 120/230V Hardwire
The Linear 2500-1944 is a 120/230V hardwire suppressor for Linear / OSCO gate operator power protection applications. It is used to reduce the effect of voltage spikes and transient events on sensitive operator electronics, especially control boards, motor drives, transformers, and accessory power circuits.
Surge suppression is especially important on gate systems because the operator is often installed outdoors with long wiring runs, metal fencing, communication wiring, and vehicle detection accessories. A suppressor can help reduce damage risk, but it does not replace proper grounding, bonding, weatherproofing, or code-compliant electrical work.
This part should be selected by the original Linear / OSCO part number and voltage requirement. A hardwired suppressor should not be added or replaced casually because incorrect line-voltage wiring can damage the operator or create a safety hazard.

Technician Note
If an operator has repeated board failures, inspect grounding, incoming voltage, conduit, water intrusion, accessory wiring, and surge protection as a complete system rather than replacing boards only.
Before Ordering
- Confirm the existing suppressor part number is 2500-1944.
- Confirm the operator voltage and wiring match 120/230V hardwire use.
- Inspect grounding and bonding before replacing surge protection.
- Do not install this on low-voltage accessory wiring unless the documentation calls for it.
- Use a qualified technician for line-voltage wiring.
Professional Advisory
Line-voltage surge protection should be installed by a qualified technician or electrician. Do not work inside an energized operator cabinet or bypass disconnects and safety procedures.
Product Q&A
What does the 2500-1944 suppressor do?
It helps protect compatible gate operator electrical circuits from voltage transients and surge events.
Is it for 120V or 230V systems?
It is commonly listed as a 120/230V hardwire suppressor.
Will this stop all lightning damage?
No surge device can guarantee protection from lightning. Proper grounding, bonding, wiring, and protection layout all matter.
Can I install it on low-voltage accessory wiring?
Only if the manufacturer documentation specifically calls for that use. This listing is for a hardwired 120/230V suppressor.
Why should a technician install it?
Incorrect line-voltage wiring can damage equipment or create an electrical hazard.
