CHINT · NXBLE-125 RCBO 10kA
Product overview
The CHINT 390186 NXBLE-125 is a two-pole magnetothermic differential circuit breaker that combines overload, short-circuit and residual-current protection in a single device. This code is rated 100A with a C tripping curve, 30mA sensitivity and a Type A residual-current characteristic, at 230/400V AC 50/60Hz. It provides 10kA rated breaking capacity (7.5kA service) to IEC/EN 60947-2 and occupies 4.5 DIN modules (81mm), so it fits standard modular distribution boards in residential, commercial and light-industrial installations.
