Mixed technology is composed of the three main components of TVS, varistors, surge arresters, and surge protectors. This type of device is used to reduce the stress on electrical circuits caused by transient over-voltages.

The P0721UARP is an electrical over-voltage protection product designed to protect and protect against the maximum surge voltage, up to 20kV per phase. The P0721UARP is designed to provide surge protection in all possible scenarios, for industrial, commercial, and residential applications. The device is UL1449 3rd Edition listed and complies with all applicable industry standards.

The P0721UARP is composed of a variety of mechanical and electrical components. The primary components of the device are its metal-oxide varistor (MOV) core, its supports, and its high-temperature resistant silicone sealant. In combination, these components make up the basic working principle of the device. The P0721UARP is designed using a thermal energy storage model. This model stores the heat from a transient over-voltage and slowly dissipates it. The MOV is a capacitor that absorbs and stores energy. When the surge voltage passes through the mov, it is converted to heat energy, which is then stored in the silicone sealant.

The MOV core is the heart of the P0721UARP’s protection mechanism. In combination with the silicone sealant, the MOV core acts as a large capacitor. The capacitance of the MOV varies depending on the voltage applied to it. When the overload voltage exceeds a certain limit, the MOV will reduce its capacitance and the energy released will be dissipated as heat. The silicone sealant helps to insulate and dissipate this heat energy.

The P0721UARP is also designed to help protect against fire hazards. Its abundant thermal energy storage system provides additional protection against arc flashes by ensuring a gradual breakdown of the arc. The P0721UARP is also designed to be vibration-resistant, providing a tighter seal around the MOV core. This helps to prevent arc faults from occurring in the device’s environment.

The P0721UARP is a durable and reliable surge protection device. Its thermal and insulation materials ensure the device will efficiently conduct transient over-voltages and help to protect your facility. Its reliable performance is certified by UL1449 3rd Edition, providing you with peace of mind that your investment is safe. So if you are looking for reliable surge protection, the P0721UARP should be at the top of your list.
