Circuit breaker
Marine Boat Shop, specialist in marine equipment for onboard energy safety and electrical system supplies
The rearmable and manual single-pole thermal circuit breaker is an electrical protection device designed to interrupt the circuit when it detects overheating or excessive current. This type of circuit breaker is commonly used in domestic, industrial, and marine applications. Here’s an overview of its features, benefits, and applications:
There are 5 products.
Reference: AD501
Disjoncteur thermique unipolaire réarmable 12/24V.
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.
