The V240RA8 is a type of metal oxide varistor (MOV) used in application fields such as protection against overvoltage and transient surges, and voltage regulation. The device works by limiting incoming excessive surge voltages and currents, or ‘clipping’ them so that current does not exceed a certain safe level. By absorbing transient surges and voltage spikes, the V240RA8 helps to protect electronic appliances and circuits from damage.The V240RA8 consists of a metal oxide plate with two electrodes which are connected, typically via a wire, between two terminals. When an excessive transient surge enters the device, the metal oxide plate absorbs the transient voltage and dissipates it as heat. The V240RA8 can absorb surges up to a certain voltage and current rating.The devices come in a variety of shapes and sizes, and the V240RA8 is a radial-style varistor with a diameter of 8mm. It is designed to handle high surge or overvoltage transients, and can provide voltage clamping protection up to 250V. The device has an 8kA current rating with a maximum peak current of 30kA, and a clamping voltage of 320V.The V240RA8 also has a number of features that add to its functionality. It has a low leakage current, which helps to prevent false triggering and ensures that the device remains inactive until a voltage surge is detected. It also has an inrush current protection feature which helps to protect sensitive components from high inrush current. The device features a built-in protection circuit that is designed to suppress EMI/RFI interference, and the device’s low capacitance helps to reduce noise and line distortion.In terms of applications, the V240RA8 is designed for use in a range of electrical and electronic applications where transient protection is required. These include power supplies, UPSs, circuit boards, and motor control circuits. It can also be used for protecting appliances, lighting systems, and medical equipment from transient surge voltages.Overall, the V240RA8 is a reliable and versatile device that can provide protection against excessive voltage transients. It is ruggedly designed and features a number of features that make it easy to use and enhance performance. This makes it ideal for use in a range of industrial, commercial, and residential applications, and is a cost-effective solution for protecting sensitive electronic equipment.
