SK829007-B RC-EH300/415 ABB RC type surge suppressor

product description

A surge suppressor, also known as a surge protector or lightning arrester, is an electronic device that provides security protection for various electronic devices, instruments, and communication lines. When the electrical circuit or communication line suddenly produces a peak current or voltage due to external interference, the surge protector can switch on the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit.
The main function of the surge voltage suppressor is to protect the system from surge high voltage damage. Uninterruptible power supplies (UPS) are used to prevent voltage drops and power disconnections, and most desktop systems have power supplies that can handle surge voltages up to 800 volts. Surge suppressors can block voltages above this level. Most surge suppressors sold today transfer the surge voltage to the ground wire, but in the wiring of some buildings, the surge voltage may reappear in other computer systems. Some surge suppressors use coils and electrolytic capacitors to absorb excess energy instead of dispersing it underground. The ground dispersion method is mainly used to protect the surge suppressor itself from being burned out. Many suppressors still use this technique, but more effective suppressors will avoid it in the future.
