TVS - Varistors, MOVs are a type of surge protection device used in a variety of applications. The V430MA3A is an example of these and is used for the protection of electrical and electronic equipment from transient over-voltage. It is designed to absorb spikes and surges that occur from a variety of sources including power systems and distribution grids, lightning, surge suppression systems, electromagnetic interference (EMI) and electrostatic discharge (ESD) requirements.

The V430MA3A is a metal oxide varistor (MOV) designed for the suppression of transient over-voltage. It is comprised of a ceramic body deposited with a zinc oxide varistor material. This material has a characteristic to dynamically change its resistance when exposed to a sudden change in voltage. When the voltage increases above its rated value, the resistance of the material decreases significantly, allowing it to absorb the surge current. When the voltage decreases again, the resistance increases, allowing it to return to normal operation. This rapid change in resistance is known as a varistor effect.

The V430MA3A is a reliable and cost-effective surge protection device used in a variety of applications. It has been tested and certified according to IEC/EN 60950-1 and BS EN61557-2 standards, proving its high performance and safety in various installations. The device has a maximum working voltage of 440VAC and its peak impulse current capability is 12.5KA. It is a medium to heavy duty design that provides excellent protection against over-voltage surges and has a minimal leakage current, making it suitable for a wide range of applications.

The V430MA3A can be used in industrial and commercial applications such as power supplies, communication systems, access control systems, lift control systems, door entry systems and other electronics equipment. It can also be used in automotive applications such as automotive HVAC systems, audio systems, power windows, and transmission control systems. It is also suitable for a variety of residential applications such as computer systems, audio and video systems, refrigerators, dishwashers, and air conditioners.

The V430MA3A is easy to install and requires only basic wiring knowledge. It can be used with a variety of load types, including AC mains, DC, and transient types. It can be used with both single-phase and three-phase power systems. Installation is completed by simply connecting the device to the approved supply circuit and mounting it in the appropriate location.

In summary, the V430MA3A is a reliable and cost-effective surge protection device used in a variety of applications. It can be used with both single-phase and three-phase power systems, and is suitable for industrial, commercial, and residential installations. It is tested and certified according to IEC/EN 60950-1 and BS EN61557-2 standards, and is easy to install and requires only basic wiring knowledge. It is designed to provide protection against transient over-voltage, and has a peak impulse current capability of 12.5KA.
