SSA24-M3/5AT

Diodes - Rectifiers - Single

Diodes are electronic devices that allow current to flow mostly in one direction and stop or restrain it in the opposite direction. A simple diode\'s primary function is that of a rectifier, constructing a circuit often referred to as a rectifier circuit. A rectifier is a circuit that is designed to convert alternating current (AC) to direct current (DC). The SSA24-M3/5AT is a single – phase thyristor surge absorber, a kind of surge protective device (SPD), that is built to do just that. It offers a protection level of up to 5 kA, making it suitable for applications in wide voltage and current ranges.

SSA24-M3/5AT application field and working principle

The SSA24-M3/5AT is suitable for a variety of applications, particularly for single-phase systems such as residential homes, factories, transformers and more. Its function is to protect systems and equipment against frequent brief over-voltages and/or impulse lightning current by acting as an effective energy dissipator. Installation of the SSA24-M3/5AT will help to prevent costly damage caused by transients or other disturbances.

The SSA24-M3/5AT works by using a thyristor surge absorber connected in parallel to the system or equipment that it is protecting. A thyristor is a kind of three-electrode device that is composed of semiconductor material and operates as both an electric switch and a rectifier. It acts like a diode, allowing current to flow in only one direction. When an electric current is applied to the SSA24-M3/5AT, the thyristor absorbs the electric charge from the power source and stores it in its capacitors until it reaches a predetermined level. Upon reaching that level, the thyristor switches open, stopping the charge from reaching its destination. This purpose of this is to absorb and dissipate the transient energy, protecting the system or equipment from damage.

The SSA24-M3/5AT also features two integrated overvoltage protection terminals which can be used to protect people and property in the event of dangerous voltage spikes. This makes it highly suitable for use at higher voltages such as those used in industrial or commercial settings.

In addition to its surge and overvoltage protection capabilities, the SSA24-M3/5AT has several other features that make it ideal for use in a variety of applications. It is built with a thermal fuse that helps to protect it against excessive temperatures, ensuring its long-term reliability and durability, and it is also designed with a vent hole that helps to dissipate excess heat and prevents the unit from over-heating and potentially malfunctioning.

In conclusion, the SSA24-M3/5AT is an extremely versatile and reliable single-phase thyristor surge absorber for industrial, commercial, and residential applications. Its surge protection capability and integrated overvoltage protection terminals make it an ideal choice for protecting valuable equipment and personnel from dangerous voltage surges. Its built-in thermal fuse and vent hole helps to keep it running at optimal temperatures, reducing the risk of failure. All in all, the SSA24-M3/5AT is a robust and reliable solution for protecting valuable equipment and personnel from damaging voltage surges.
