1/4HP. 220V.Overload Protector.OL-008.
This device is an OL-008 Overload Protector, a critical safety component for refrigeration and air conditioning compressors.
Technical Specifications
- Model/Part Number: OL-008.
- Horsepower (HP) Rating: Specifically designed for 1/4 HP compressors (as indicated by the “OVER LOAD 1/4” text in the image).
- 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 secure installation.
Core Function & Safety
The primary job of this overload is to act as a safety circuit breaker for the compressor motor:
- Thermal & Current Monitoring: It contains a bimetallic strip that senses both the temperature of the compressor and the electrical current (amperage) it draws.
- Safety Shutdown: If the compressor draws excessive current or begins to overheat (due to a mechanical stall, low voltage, or high ambient temperatures), the bimetal strip “pops” open.
- Motor Protection: This instantly cuts power to the compressor motor to prevent it from burning out its internal windings.
- 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.
