Description

Technical Field

[0001] The utility model relates to the technical field of overload protectors, in particular to a compressor overload protector with dual protection functions. Background Art

[0002] A compressor overload protector is a safety device designed to prevent damage to the compressor due to excessive current or high temperature. It monitors the operating current and temperature of the compressor. When these parameters exceed safety thresholds, the protector automatically cuts off power to protect the compressor from overload and damage.

[0003] Existing overload protectors are usually fixed directly on the compressor. When the compressor is working, it will vibrate. Since the current overload protector does not have a buffer structure, the overload protector will vibrate, which may cause the components inside the overload protector to move. In addition, during the vibration, the wiring on the overload protector may fall off, thereby affecting its use. Utility Model Content
