ROV14-621K

The ROV14-621K is a state-of-the-art, high performance, thermally enhanced varistor manufactured by Raychem. It is designed to provide increased current capacity, current distribution, and surge protection in a compact package.

Varistors are AC voltage-dependent resistors that can be used to protect electronic circuits from over-voltage transients. They are usually used in conjunction with Metal Oxide Varistors (MOVs) for surge protection in power systems, thereby providing effective protection from transient over-voltage. The ROV14-621K is the latest in a line of thermally enhanced varistors manufactured by Raychem.

The ROV14-621K provides superior performance, with its high-temperature rating of 125°C, high-current rating of 6.21kA, and low voltage threshold of 160 VAC. It also features a low dynamic capacitance of 0.25pF, a twin-spring contact arrangement, and a thermally enhanced construction that enables superior current distribution and prevent thermal runaway. Furthermore, the device is designed to be easily mounted in any orientation and is suitable for use in both indoor and outdoor environments.

In operation, the ROV14-621K acts as a voltage-dependent resistor, providing a low impedance path for transient over-voltages. When the voltage exceeds the rated threshold, the device begins to conduct, dissipating the energy of the over-voltage surge. The device also provides protection against short duration over-voltages, preventing equipment damage.

The ROV14-621K is ideal for industrial, commercial, and residential applications. It can be used to protect sensitive electronic equipment from high-Energy transients resulting from lightning strikes, power outages, or short circuits. It is also well-suited for use in high-voltage applications, such as switch gear, main distribution panels, and large industrial machinery. The device’s high current rating and low voltage threshold make it suitable for a variety of applications where reliable protection is needed.

In conclusion, the ROV14-621K is a state-of-the-art thermally enhanced varistor designed to provide increased current capacity, current distribution, and surge protection in a compact package. It is an ideal solution for a variety of applications ranging from industrial and commercial to residential. Its superior current rating and voltage threshold make it well-suited for protecting costly electronic equipment from damaging transients.
