The Terasaki ZS100-NF ELCB is a heavy-duty 4-pole earth leakage circuit breaker designed for advanced protection against earth faults, leakage currents, and electrical hazards in three-phase electrical installations. Engineered for 415VAC systems, it delivers a high AC breaking capacity of 25kA (up to 30kA), ensuring dependable fault interruption even in high-fault-level environments.
Available in 30A, 60A, and 100A current ratings, the ZS100-NF supports a wide range of industrial and commercial applications. Its selectable rated sensitive currents of 100mA, 200mA, and 500mA allow precise leakage protection for both personnel safety and fire prevention.
With 4-pole switching (3P + N), the breaker disconnects all phases and neutral simultaneously, offering complete isolation and enhanced system safety. Built with TERASAKI’s Japanese engineering quality, the ZS100-NF ensures stable performance, long service ...
