thermal fuse
Tamura/NEC SF metal casing 15A Temperature fuse
The working principle of the AUPO / Tamura / NEC SF thermal fuse is based on the thermal expansion and conductive properties of the material. When the temperature in the circuit rises to the rated trigger temperature of the fuse, the metal material of the fuse will expand due to heat. When this expansion reaches a certain degree, it will cause the resistance inside the fuse to rise sharply.
The Difference Between Thermal Fuse Link and Thermal Cutoff Switch
A “thermal fuse link (Fusible alloy wire and Organic thermal fuse )” is essentially a one-time fusible cut off, heat-sensitive component that permanently breaks a circuit when it reaches a specific temperature. while a “thermal cutoff switch” is a bimetallic strip device that can potentially cut off itself after reaching a high temperature, allowing the circuit to reconnect once the temperature drops below a set point.
Therm-O-Disc microtemp fuse G5 for Refrigerator / Coffee maker
“Therm-O-Disc” thermal disc manufactured G5 series MICROTEMP® thermal fuse, specially designed for high current loads, depending on product specifications, contact capacity were up to AC250V 16A, AC250V 20A and AC120V 25A, entirely through the agency approvals UL and CSA.
thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
Thermal Fuse Function and Application
The Thermal Fuse (Thermal Cutoff, Temperature Fuse) is Axial / Radial / Organic Thermal-Link(OTCO) safety parts that stops the flow of electricity to the motor circuit when a overheats. If the fuse is missing or broken, your motor will not start. The thermal fuse is sensitive to external temperature, and the operating temperature is accurate and stable. Small size, sealed structure. Reliable performance. Low resistance value. One-time action cuts off the current, and the current interruption capacity reaches 250VAC/25A.
Thermik Pressure Resistant Round Thermal Protector S01
The temperature switch (thermal protector) produced by THERMIK Company is characterized by its small size, extremely high mechanical stress resistance, high shock resistance, and excellent stability. PTC thermistor is characterized by small size, fast response, 4 layers of protection, and 3 heads connected in series. It can be buried in the three-phase coil of the motor and can protect different temperatures.
