Nanocrystalline cores

RCCB (Residual Current Circuit Breaker)

RCCB High Performance Nano Crystalline Safety Cores

Advanced RCCB Cores for Residential and Industrial Safety

Designed for both 2-pole and 4-pole systems, they offer superior thermal stability and reliability to keep personnel and equipment safe.

RCCB Nano Crystalline Cores for Enhanced Leakage Protection

Voltage-independent Residual Current Circuit Breakers (RCCBs), enhancing safety in both residential and industrial electrical systems. RCCBs detect leakage currents and disconnect the power supply when faults occur, ensuring personnel and equipment safety. These toroidal-shaped cores, encased in protective plastic, are optimized for different RCCB types, including electronic and electromagnetic variants. They support 2-pole and 4-pole configurations with rated currents ranging from 10A to 100A and sensitivities of 30mA, 100mA, and 300mA.
