Motor overload protecting device, motor start device, backup protecting element and process for obtaining a backup protecting element

An overload protecting device for use in a motor of a refrigeration equipment, the device comprising:

• a main module;
• and
• a backup protecting element associated to the main module, the backup protecting element comprising:
• a first connection means associable to an electric energy feeding source;
• a second connection means associable to a motor;
• and
• a fusing linkage directly connecting the first connection means to the second connection means, the fusing linkage being configured to interrupt the electric current that runs through the motor, and wherein the first connection means, the second connection means, and the fusing linkage are fully associated to each other in a single part.

A backup protecting element for use in a motor protecting device in a refrigeration equipment, the backup protecting element comprising:

• a first connection means associable to an electric energy feeding source;
• a second connection means associable to a motor of the refrigeration equipment;
• and
• a fusing linkage directly connecting the first connection means to the second connection means, the fusing linkage configured to interrupt the electric current that runs through the motor, wherein the first connection means, the second connection means, and the fusing linkage are fully associated to each other in a single part.

A process for obtaining a backup protecting element for use in a motor protecting device, the process comprising the steps of:

• A) coining and cutting a metal part in order to obtain a connector provided with a first connection means associated to a second connection means through an intermediate portion;
• B) coining a part of the intermediate portion obtained in step A) to adjust said part to a preset thickness that forms a pressed part of the intermediate portion;
• and
• C) cutting said pressed part of the intermediate portion obtained in step B) to obtain a fusing linkage.
