17AM temperautre and current control type thermal protector
Key Features
Dual Protection: Safeguards against both excessive temperature and current.
Compact Design: Small footprint for easy integration into various applications.
Reliable Performance: Proven reliability and durability in demanding environments.
Fast Response Time: Quick action to protect components from damage.
Wide Temperature Range: Available in various temperature settings to suit diverse applications.
Customizable Options: Tailored solutions to meet specific requirements, including custom temperature ratings, contact configurations, and lead wire specifications.
Working Principle
Temperature Sensing: The bimetallic element, sensitive to temperature changes, expands or contracts when the temperature exceeds a predefined threshold.
Mechanical Action: The expansion or contraction of the bimetallic element triggers a mechanical action that opens or closes the electrical contacts.
Circuit Interruption: When the temperature reaches the critical point, the contacts open, interrupting the power supply to the protected component.
Automatic Reset: Once the temperature drops below the reset threshold, the contacts automatically close, restoring power to the component.
Applications
The 17AM series thermal protector is widely used in a variety of applications, including:
Motors: Protects motors from overheating due to overload or stalled rotor conditions.
Transformers: Prevents overheating and extends the lifespan of transformers.
Lighting Fixtures: Safeguards lighting fixtures from excessive heat and current surges.
Battery Packs: Protects battery cells from overheating and potential fire hazards.
Power Supplies: Protects power supplies from overload and short-circuit conditions.
Household Appliances: Safeguards various household appliances, such as refrigerators, washing machines, and air conditioners.
Automotive Components: Protects automotive components like relays, solenoids, and motors.
