PTC (positive temperature coefficient) resettable fuses are electronic devices that protect heavy-duty industrial equipment from overheat and overcurrent conditions. They provide overheat protection when the temperature of the equipment or its components reaches dangerous levels, and they provide overcurrent protection when the flow of current exceeds the maximum recommended level. In addition, they are self-resetting, meaning that when the overheat or overcurrent condition is resolved, the fuse automatically returns to normal operation.

The 16VT175SU is a PTC resettable fuse designed to protect industrial machinery and equipment from dangerous conditions. It is a two-pole, single-phase device that monitors both temperature and current simultaneously. The temperature detection range is 0°C to 212°C. The device has a 6 kA rated current at an operating temperature of 25°C, and the maximum current is 20kA.

The 16VT175SU is used in a wide range of industrial applications, including heating, ventilation, and air conditioning systems; automotive electronics; motors and generator controls; and consumer electronics. It is ideal for use in high-temperature and high-current applications, as it provides reliable protection against overheating and overcurrent conditions.

The 16VT175SU utilizes a PTC thermistor to detect temperature and an internal resistive element to detect current. The PTC thermistor is a temperature-sensitive resistor that changes its resistance as the temperature of the device increases. As the temperature rises, the resistance of the PTC thermistor increases rapidly, creating an open circuit. This open circuit is detected by the internal resistive element, which responds by cutting off the supply current.

The 16VT175SU also has an overcurrent protection feature. When the internal resistive element detects a current higher than the set level, it creates an open circuit, cutting off the supply current. This prevents the device from experiencing an overload condition.

When the device returns to an acceptable temperature and current, the PTC thermistor and the internal resistive element reset, restoring the supply current. The 16VT175SU is designed to be used in extreme temperatures and high current settings, and it is rated to withstand temperatures up to 425°C and currents up to 20kA.

The 16VT175SU is a reliable and cost-effective solution for industrial applications that require reliable protection against both overheating and overcurrent conditions. Its ability to reset itself after experiencing a fault makes it an ideal solution for high-temperature and high-current environments.
