Fuses play an essential role in electrical systems, providing important protection in a wide array of applications. The BK/TDC11-100MA, a thermal cutoff device from Chinese manufacturer Cixi Changling, is a fast-acting, overcurrent fuse for low-current applications. In this article, we\'ll take a look at the BK/TDC11-100MA\'s applications and working principle.

Applications

As a thermal cutoff device, the BK/TDC11-100MA is best suited for low-current applications, such as household appliances, audio/video equipment, and computer peripherals. The fuse has a rated voltage of 250V AC and a rated current of 0.1A, making it suitable for applications with currents of up to 100mA. The BK/TDC11-100MA also features fast-acting response and tight temperature tolerances—it can trip at temperatures as low as 85 °C.

The BK/TDC11-100MA is designed with a slim tin-plating profile, so it can fit into tight spaces. The fuse also features long-term reliability and a long life span, and its reversible design makes it easy to install. The BK/TDC11-100MA has a UL-94 V-2 flammability rating, so it can be used in hazardous areas.

Working Principle

The BK/TDC11-100MA is a thermal cutoff device, meaning it trips at a set temperature. The device works by delimiting a thermal fuse element, which is a type of resin-coated heat sensitive strip. When current passes through the device, it generates heat, causing the thermal fuse element to expand. Once the device reaches a predetermined temperature, the thermal element will expand and break the circuit, cutting off the flow of electricity.

The BK/TDC11-100MA\'s overcurrent protection works by monitoring the current and comparing the measured value against the set threshold. When a current above the set threshold is detected, the device will trip and break the circuit. This process happens in a matter of milliseconds, ensuring the device can provide fast and reliable protection.

The BK/TDC11-100MA is also designed with a reverse current detection feature. When the device senses a reverse current, it can alert the user and automatically trip the circuit, preventing damage and providing additional protection for the user.

Conclusion

The BK/TDC11-100MA is a thermal cutoff device from Chinese manufacturer Cixi Changling. This fast-acting, overcurrent fuse is designed for low-current applications, such as household appliances, audio/video equipment, and computer peripherals. The fuse has a rated voltage of 250V AC and a rated current of 0.1A, and can trip at temperatures as low as 85 °C. The BK/TDC11-100MA also features an reverse current detection feature, ensuring reliable protection for the user.
