    Structure and working principle

    Thunder Hao SCB series backup protectors are suitable for TT, TN and other power supply systems under 50/60Hz and various voltages. It solves the problem of lightning arrester failure caused by malfunction of the backup protection device caused by lightning and ensures that the surge protector (SPD) does not catch fire, and the equipment’s lightning protection is continuously effective; at the same time, it effectively overcomes the protection blind zone problem caused by the widespread use of fuses or circuit breakers as external disconnectors. It is an ideal match for voltage switching SPD and voltage limiting SPD in low-voltage power supply systems. device. The product complies with GB/T 18802.11, IEC61643-1 and other standards.

    Install

    * Selective control of tripping mechanism segments is achieved through changes in current parameters;

    * The impulse current residual voltage is low, and the test performance is better than that of circuit breakers and fuses; the use of high-energy materials solves the problem of product service life;

    * Strong surge current tolerance and no malfunction;

    * Tripping occurs when the power frequency current exceeds 3±1A;

    * Strong operating short-circuit current breaking capability;

    * It adopts parameter control tripping mechanism and is installed on 35mm guide rail;

    * Complete specifications can meet T1, T2 and T3 level SPD matching;

    * Optional remote control alarm.
