OEM High Quality Dc Spd Exporter – CHXI SPD has reliable voltage protection level and safe characteristic of overload,stong discharge current capability – Sofielec Electrical

Product Description

CHXI-I25：SPD special backup protector(special backup protection device for lightning protection) , to solve the lightning protection device due to deterioration and power grid failure caused by fire hazards, to solve the lightning protection device caused by the wrong operation of the backup protection device caused by lightning failure, to ensure that the surge protector(SPD) does not fire, equipment lightning protection continues to be effective； At the sametime, it can effectively overcome the protection blind area problem that exists in the widely used fuse or circuit breaker as the external disconnector.It is an ideal supporting device for the voltage switching SPD and voltage limiting SPD of the low-voltage powersupply system.

Adopt high-energy contact, long service life; The ability to withstand the impact of current is strong, no wrong action;

◆Power frequency current through more than 3±1Atrip：
Running short circuit current breaking ability is strong;

Adopt parameter control tripping mechanism, 35mm guiderail installation;

◆Complete specifications can meet T 1, T 2, T3SPD matching：
It can selectively cutoff the power frequency current and the lightning current, which can effectively protect the SPD from break-through and short circuit due to abnormal transient overvoltage, resulting in serious fire accident.
Selective breaking of the power frequency current and the lightning current through the SPD surge protector can effectively protect the SPD surge protector due to the deterioration of the SPD starting voltage to fall below the powersupply voltage, power frequency leakage current increases.causing serious fire accidents.When the lightning current of SPD is out of date, the external detachment device will not be mi stripped, so that the lightning protection of electrical equipment is always in an effective state.

It can provide professional backup protection for the first level, second level, third level power lightning protection equipment(SPD surge protector) .It is applicable to the places where SPD lightning protection equipment has been installed, such as：industrial and civil construction, electrical.communication, road traffic, petrochemical and other industries of power equipment.
