Surge Device SR1040HC0G is a Single Pole Surge Protective Device (SPD) designed to protect electrical devices against over-voltage. It provides high quality protection in a wide range of lightning, Surge, transient and ESD protection. It features low capacitance to reduce loads on the circuit and includes a protection indicator to indicate the protection status at a glance.

The SR1040HC0G is a 1-pole surge arrester with bridge rectifier and pre-tensioning spring. Basically, this type of surge arrester is made of two parts, the SPD (Surge Protective Device) and the bridge rectifier. The SPD is responsible for providing the necessary protection and the bridge rectifier is used to channel the surge and transient current. The pre-tensioning spring increases the current carrying ability of the SPD and reduces the stress on the terminal connections of the surge arrester.

SR1040HC0G is usually used in the residential, commercial and industrial applications. It is suitable for AC, DC and AC/DC applications, and can be used to protect a wide variety of electrical, electronic and communication devices from damage due to lightning, transient or ESD surge. It is also suitable for use in the automotive, medical or control system because of its low-capacitance characteristics.

The working principle of SR1040HC0G is relatively simple and straightforward. When a surge or transient current is applied, the SPD is triggered and the voltage across the SPD begins to rise. The SPD limits the voltage across it, thus clamping the surge energy and dissipating it into the ground. The bridge rectifier then redirects any remaining surge or transient current to the ground, thus reducing the impulse voltage to a safe level.

In summary, the SR1040HC0G is a single pole surge protective device designed to provide superior protection and minimize damage caused by over-voltage. The low-capacitance characteristics make it suitable for use in a variety of environments and applications. The pre-tensioning spring ensures that the surge arrester can handle high currents without damage, and the protection indicator provides status indication in a glance.
