The CHINT NB1L (RCBO) provides complete protection against earth leakage, overload, and short-circuit conditions, ensuring both electrical safety and fire prevention. This RCBO is type A, which detects both AC and pulsing DC residual currents. NB1L RCBO is used for residential and light commercial circuits, particularly those using mixed loads such as lighting, sockets, and small motors. Additionally, this NB1L supports top and bottom wiring, and can be mounted on standard DIN rails using a fast clip-on mechanism for easy installation. With 10 kA breaking capacity and leakage sensitivities of 30mA, the NB1L is reliable, compact, and compliant with IEC/EN 61009-1 standards.
