PROSURGE iSPD/C320-4P-SCB is an intelligent and auto self-protected SPD for three phase power systems. It’s an innovative solution for most commercial and industrial environments with critical operations, to make your surge protection smart and intelligent.it is composed of two essential parts: surge protective device (SPD), and surge circuit breaker (SCB).
PROSURGE high performance SPDs (Class II per IEC 61643-11) of iSPD/C320-4P-SCB can protect sensitive equipment from the harmful transient voltage surges resulting from:
Direct and indirect lightning strikes
Power company load switching
Upstream load switching at other facilities
PROSURGE SCB provides backup over-current protection for the SPD, which is fully coordinated with the surge protective device. Comparing to normal backup circuit breaker/fuse, the integrated PROSURGE SCB achieve a better balance between surge withstand performance (no tripping while expected surge occurs) and sharp reaction against short circuit and abnormal leakage current.
Typical Applications:
Commercial
Industrial
Communications
Renewable energy
Critical power (hospitals, data centers, etc)
Features:
High performance KEMA certified SPD inbuilt with Imax 40kA 8/20 and In 20kA 8/20 for Class II application, comply with IEC/EN 61643-1/11standards;
Pluggable module of SPD for easy replacement
Self protected by PROSUGE innovated Surge circuit breaker technology, SPD will never stop service in the life time and no fire risk while in the end of life
IP20 enclosure to resist dirt, dust and water
Model: iSPD/C320-4P-SCB
This model is composed of two essential parts: surge protective device (SPD) and surge circuit breaker (SCB). This product is pre-wired and easy to be installed as a completed unit, which is an upgraded design to replace the conventional installation assembly of the SPD and backup over-current protection devices.
PROSURGE SCB provides excellent backup over-current protection and fully coordinated with the SPD. Comparing to normal backup circuit breaker/fuse, the integrated PROSURGE SCB achieves a better balance between surge withstand performance (no tripping while expected surge occurs) and sharp reaction against short circuit and abnormal leakage current.
