TSCB's new SPD dedicated backup protection device, TSCB is a backup protection device designed for SPD.
It uses innovative technology to perfectly solve the problem of improper use of circuit breakers and fuses
as SPD back protection devices. And other issues. On the one hand, TSCB has the electrophoresis withstand
capability matched with SPD, ensuring no malfunction during lightning current surge. On the other hand,
TSCB can quickly and quickly when SPD short-circuit failure or line-frequency short circuit occurs due to TOV.
Cut off the short-circuit current to avoid SPD fire, explosion, and safely and effectively protect the line.
The new products are divided into SPD-specific TSCB-T1 first-class protection, SPD-specific TSCB-T2
two-class products, providing professional and comprehensive protection for SPD.
1.Surge withstand capability: TSCB has a surge withstand capability of up to 25 kA for 10/350us waveforms and up to 120 kA for 80/20us waveforms.
2.Power frequency overcurrent protection: TSCB has a wider range of power frequency overcurrent protection. It has excellent comprehensive performance in high short circuit breaking and low short circuit moment, which can protect SPD from TOV damage. TSCB can cut off peaks up to 100KA. High short-circuit current, and can cut off low short-circuit current above 3A in a very short time.
3.Voltage protection level: TSCB has lower residual voltage at both ends when electrophoresis occurs, and the corresponding TSCB branch has lower effective voltage protection level, so the device can be better protected.
4.Dimensions: TSCB is compact and compact, and its width is only 18mm per pole, which greatly saves installation space.
5.Coordination with SPD: TSCB and SPD are perfectly matched, and the matching scheme has passed a full set of test verification.
