Compactor Electrical Parts & Components
Replacement electrical parts for industrial trash compactors — limit switches, safety switches, pressure switches, photo eyes, emergency stops, push buttons, control panels, PLCs, PCBs, and transformer fuses. OEM-compatible with Marathon, PTR, Wastequip, Harmony, and SP Industries.
What this page covers
The electrical system is the most common source of compactor downtime. Switches fail from vibration and contact wear, photo eyes lose alignment, control transformers blow fuses, emergency stop buttons get stuck or vandalized, and control boards age out of compatibility with replacement parts. Each of these is a 30-minute repair if you have the right part on hand — and a 3-day downtime if you don't.
PRT stocks every commonly-replaced electrical component for industrial compactors, organized by function: Switches (limit, safety, photo, pressure), Buttons & Keys (30mm and 22.5mm in operator and emergency-stop styles), Panels & Controls (PLCs, PCBs, operator and motor driver controls), Motors and motor starters, and Transformer/Fuses. Most replacements ship same business day.
How to choose
Start by identifying the failed component on the compactor's electrical schematic — usually inside the control panel door. Match the OEM part number to a PRT replacement; for most components, the OEM part number translates directly. If the part is unmarked or damaged, send PRT a photo and we'll identify it.
For older compactors with discontinued OEM parts, PRT can recommend equivalent replacements that drop into the existing control system. We can also recommend control-panel upgrades (PLC retrofits, contactor replacements) when the original parts are no longer available.

Frequently asked questions
What's the most common electrical failure on an industrial trash compactor?
Control transformer fuses are the most common single failure. The second most common is photo-eye sensor misalignment or contamination — easy to fix in the field. Third is limit-switch contact wear, particularly the cycle-end limit switch that takes thousands of hits per year.
Are PRT electrical parts OEM-compatible with Marathon, PTR, and Wastequip compactors?
Yes. PRT supplies OEM-spec replacements for Marathon, PTR, Wastequip, Harmony, and SP Industries. Provide the compactor model and the failed component's part number — we'll match exact replacements where available and high-quality aftermarket equivalents where OEM parts are discontinued.
Can I upgrade my compactor's electrical system to modern PLC controls?
Yes. PRT supplies PLC retrofit kits for older relay-logic compactors. The retrofit typically requires a control panel rebuild but extends compactor life by 10+ years and adds cycle counters, run-time meters, and remote-monitoring options.
How fast does PRT ship electrical parts?
Most in-stock electrical components ship the same business day from Schaumburg, IL. Specialty items and OEM-discontinued replacements may ship in 2-3 business days.
