1/3 HP compressors. 220V. Overload Protector.OL-007
This device is an OL-007 Overload Protector, a critical electrical safety component for refrigeration and air conditioning compressors.
Technical Specifications
- Model/Part Number: OL-007.
- Horsepower (HP) Rating: Specifically designed for 1/3 HP compressors (as marked on the housing).
- Voltage/Frequency: Rated for 220V AC at 50/60Hz.
- Type: External thermal overload protector with an integrated lead wire.
- Terminals: Features a male spade terminal on the body and a female spade connector at the end of the black lead wire for easy “plug-on” installation.
Core Function & Safety
The primary job of this overload is to act as an automatic safety switch for the compressor motor:
- Dual Sensing: It contains an internal bimetallic strip that monitors both the electrical current (amperage) and the physical heat of the compressor.
- Safety Shutdown: If the compressor draws excessive current or begins to overheat (due to a mechanical stall or high ambient temperatures), the bimetal strip “pops” open, instantly cutting power.
- Motor Protection: This prevents the compressor’s internal copper windings from burning out, which would otherwise require a total compressor replacement.
- Automatic Reset: Once the compressor and the overload part cool down to a safe level, the bimetal strip resets, allowing the compressor to attempt another start.
