Overview
The iEF-CLP Series Electrical Fire Current-Limiting Protectors can rapidly limit short-circuit currents at microsecond-level speeds, providing arc-extinguishing protection. The current is limited before the short-circuit reaches its full magnitude, preventing continuous arcing and sparks that could ignite combustible materials during electrical faults.
This product uses high-quality imported power MOS devices, featuring low on-resistance and a wide safe operating area. It offers high reliability, stability, redundancy, and safety.
