Power surge protection device household circuit surge arrester safety protection
Product Details
Surge protector is an electronic device that provides security protection for all kinds of electronic devices, instruments and communication lines. When the peak current or voltage is suddenly produced in the electrical circuit or communication line because of the external interference, the surge protector can guide the shunt in a very short time, thus avoiding the damage to the other equipment in the circuit. It is usually installed in the floor distribution box, computer center, telecommunication machine room, elevator control room and so on.
Product features
1. temperature control protection circuit, built-in thermal protection;
2. safety insulation of fire retardant and high flame retardant material
3. The design and installation of the module are convenient and can be replaced directly.

Working principle of product
The function of surge protector is to limit the transient overvoltage to the power line, the signal transmission line in the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and protect the protected equipment or system from damage by the impact.
Use of attention
1. the extra voltage drop caused by the device terminal.
2. and SPD is established.
3. limit the inductive coupling between the protected part after installation and the part of the unprotected device, so we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.
