The K180A0385-3 is a latch cover and switch assembly built for select three-phase LiftMaster commercial gate operator applications. The latch cover protects and supports the switch area, while the switch function is part of the operator service and access arrangement. On commercial slide gate equipment, damaged latch covers or faulty switches can create service access problems, power-control issues, or unreliable operator operation.
This part must be matched carefully because three-phase gate operators use different electrical arrangements than single-phase operators. Similar switch assemblies may look close but have different ratings, mounting, or wiring. SL585UL and SL595UL are the strongest specific references found, with broader LiftMaster gate operator language kept parts-diagram dependent.
Compatibility is for select LiftMaster three-phase gate operators. Confirm the original parts diagram and voltage/phase before ordering.

Before replacing this assembly, confirm whether the problem is mechanical latch damage, switch failure, wiring damage, or a power supply issue. Three-phase operator service should not be guessed by appearance.
Disconnect power before servicing the operator. For high-voltage wiring, three-phase equipment, moving gate hardware, or uncertain diagnosis, use a qualified gate technician. Do not bypass entrapment protection or safety devices to make an operator run.
3PH refers to three-phase operator applications. This part should not be used as a substitute for a single-phase switch assembly.
SL585UL and SL595UL are specific model references found for this latch cover and switch assembly, with broader gate operator compatibility dependent on the parts diagram.
No. It is commonly described as a latch cover and switch assembly, so both the protective cover and switch function matter.
No. It should only be installed where the exact three-phase parts diagram calls for K180A0385-3.
Because this is tied to commercial three-phase equipment, installation should be handled by a qualified gate technician or electrician.
