CHINT NXBL-40Y Residual Current Operated Circuit Breaker,
combines residual current and over-current protection in one device,
ensuring comprehensive safety for personnel, equipment, and wiring.
It detects earth faults, overloads, and short circuits, automatically disconnecting the circuit to prevent electric shocks and fires.
With a rated breaking capacity of 4.5kA, sensitivity from 30mA to 300mA,
and tripping curves (B or C) for diverse applications, the NXBL-40Y offers high reliability,
compact design, and CE-certified performance for residential, commercial, and industrial power systems.
