Abstract

A starting device for compressors has a PTC resistor and a protection device, both of which are inserted in a casing fitted with couplings for connection to the standard coupling pins present on compressors. A start capacitor or a run capacitor is also included in the casing. The device has a box-shaped casing with teeth or the like which is designed to snap onto the compressor structure, which box-shaped casing contains a thermal protection device, a starting device, in particular constituted by a PTC resistor, and a capacitor which may be a start capacitor or a run capacitor, as the case may be. The casing is fitted with a connector for connection to the pins of the standard connectors on compressors so that the assembly can be fitted simply by connecting the device to the compressor connector, the casing being snap-fitted into its seating in such a way as to eliminate the risk of its becoming disconnected even as a result of vibrations transmitted by the compressor motor.
