JMACD-6XP

JMACD-6XP is a commercial grade, medium strength, positive temperature coefficient (PTC) overload protector used as secondary current limiter. It is designed to protect electrical circuits against short-circuit currents, providing operational flexibility and making the power circuits more reliable. It is mainly used in industries such as commercial, industrial, medical, and aerospace.The JMACD-6XP comes in two versions: JMACD-6XP and JMACD-6XP/C. The JMACD-6XP is the most commonly used type, and it has a normal current range between 10 and 50 amps. The JMACD-6XP/C is specifically designed for applications up to 150 amps. Both versions of the PTC are designed with three characteristics that provide the protection and flexibility needed for an effective overload protector: a heating element, a heat-sensing element, and a temperature-control element.The heating element is the PTC\'s primary mode of protection and is designed to short-circuit overload currents. The PTC contains a resistive material that is heated by an electric current. When the current overloads the circuit, the resistive material ramp up its temperature and causes the PTC to short-circuit the overload current, thus protecting the electrical circuit.The heat-sensing element is the second type of protection used in the PTC and is designed to detect elevated temperatures in the resistive material. When the temperature of the resistive material rises, the heat-sensing element triggers a secondary short-circuit, thus eliminating the overload permanently.The temperature-control element is the third and most important type of protection used in the PTC. This element is designed to prevent excessive heating of the resistive material and to extend its life. The temperature-control element must sense when the resistive material reaches its maximum operating temperature and must tripping the circuit when that threshold is exceeded. This ensures that the PTC will not overheat and will remain operational until it is manually reset.The JMACD-6XP is an ideal choice for a wide variety of applications, providing dependable short-circuit protection and operational flexibility. In addition to the basic three-prong PTC design, custom designs are available that can be modified to the specific application. Some examples that JMACD-6XP can be used for include circuit protection in high-voltage circuit breakers, anti-clockwise protection for electric forklifts, window switching in jet engines, and as a replacement for traditional fuses in control panels.By combining its three characteristic elements, the JMACD-6XP provides an effective solution for overload protection in a wide variety of commercial, industrial, medical, and aerospace applications. Its small size and versatility make it an attractive choice for designers and manufacturers who need secondary current limiters with minimal installation space requirements.
