Main Features

Thermal:
Uses a thermal mechanism to detect current overloads. When the current exceeds a certain value, a thermal element expands, triggering the circuit to open.

Single-Pole:
Designed to protect a single circuit or phase, making it suitable for applications where only one power line is needed.

Rearmable:
Can be reset after tripping. Once the issue is resolved, the user can restart the breaker without the need for replacement.

Manual Control:
Equipped with a lever or button allowing the user to manually disconnect the power, useful for maintenance or in emergencies.

Varied Capacities:
Available in different current ratings, tailored to the specific needs of the application.

Advantages

Ease of Use:
Easy to reset and use, with direct access for manual control.

Reliable Protection:
Responds quickly to overloads and short circuits, protecting connected equipment.

Cost-Effective:
No need to replace the device after tripping, reducing maintenance costs.

Disadvantages

Sensitivity:
Can be sensitive to current fluctuations, potentially causing unwanted trips in some cases.

Slower Response:
Compared to electronic circuit breakers, thermal breakers may react more slowly to short circuits.

Applications

Domestic Installations:
Used to protect electrical circuits in homes, such as lighting and outlets.

Marine Equipment:
Found in boat electrical systems to protect circuits from overloads.

Industrial Applications:
Used in machines and equipment to prevent damage from current overloads.

Recreational Vehicles (RV):
Often used to protect the electrical systems in recreational vehicles.

Conclusion
The rearmable and manual single-pole thermal circuit breaker is an essential protection device offering a practical and reliable solution for managing current overloads. Its resettable feature and manual operation make it a popular choice for various applications, ensuring the safety of electrical systems.
