PTC resettable fuses are designed to protect against short circuit current, overcurrent protection, and other circuit malfunctions. They offer an alternative to traditional circuit breakers or fuses, offering a cost-effective solution that provides high-current protection with a low profile. The PTCTZ3NR150KTE fuse is a three-pin through-hole resettable fuse that offers up to 150A of current protection. This fuse is typically used in power supplies, motors, and heavy-duty industrial applications.

The working principle of the PTCTZ3NR150KTE resettable fuse is simple yet effective. It is composed of a PTC (positive temperature coefficient) element. This element comprises of a conductive polymer and a particle embedded in its structure. When the circuit goes out of balance, the temperature of the element increases. As the temperature increases, the resistance of the element also increases. When the current reaches a certain level, the resistance is high enough to prevent any further increase of current. This limits the damage caused by overcurrent faults.

When the current has fallen back to normal levels, the element cools down and its resistance lowers, allowing the circuit to reset automatically. This eliminates the need to continuously replace fuses or circuit breakers. The PTCTZ3NR150KTE fuse has a wide range of application areas, from appliance and consumer electronics to industrial and hazardous location applications. It is suitable for use in any application where overcurrent protection is required, such as power supplies, motor control, lighting circuits, and inverters.

The PTCTZ3NR150KTE resettable fuse is designed to be used in many different power distribution systems, including DC power systems, 3-phase AC systems, and even high voltage AC systems. This makes it an ideal solution for a wide range of applications. It is also environmentally friendly, as it does not generate any toxic byproducts. In addition, it is RoHS and REACH compliant, making it safe for use in any environment. With its easy installation and simple operation, the PTCTZ3NR150KTE resettable fuse is a great choice for overcurrent protection.
