Electrical safety is a priority in any work or residential environment, and although it often goes unnoticed, thermal protection plays a crucial role in preventing accidents and breakdowns.

 

What is thermal protection?

Thermal protection is a safety device, usually a bimetallic thermostat, incorporated into the electrical cable reel. Its function is to automatically interrupt the electric current whenever the internal temperature exceeds a safe limit, preventing the system from overheating.

 

Why does overheating occur?

Excessive temperature increases can happen for several reasons, such as:

• Electrical overload when the current exceeds the rated value of the cable reel;
• Connection of equipment with power above the recommended;
• Use of the coiled cable with high current, which makes it difficult to dissipate heat;
• Hot environments or lack of adequate ventilation.

In these cases, the thermal device acts automatically, cutting off the electrical current and preventing damage to the conductors and cable insulation.

 

How does thermal protection work?

Thermal protection continuously monitors the internal temperature of the reel, especially in the reel or conductor area. When the heat reaches critical levels, the system shuts down the circuit and keeps the equipment protected until it cools down.

In ASLO’s cable reels, the reset is automatic, eliminating the replacement of fuses and promoting continuous and safe use.

 

Key benefits

• Electrical safety: Prevents short circuits, accidents and fire hazards caused by overheating.
• Equipment protection: Prevents damage to conductors and extends the life of the reel and cable.
• Maintenance savings: Avoids costs with repairs or replacements due to thermal failures.
• Ease of use: The automatic system allows normal operation to resume after cooling, without the need for technical intervention.
