The CHINT NB2LE-63 1P+N C50 30mA AC is a residual current operated circuit breaker designed for:
- Rated voltage: 240V AC
- Rated current: 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A
- Leakage protection: Trips at 30mA to protect against electric shocks and earth faults
- Overcurrent protection: Built-in protection against overloads and short circuits
- Curve C tripping characteristics: Suitable for circuits with moderate inrush currents (like lighting, sockets, and small appliances)
Type: Differential Circuit Breaker (RCBO – Residual Current Breaker with Overcurrent Protection)
Poles: 1P+N (1 Pole + Neutral)
Rated Current (In): 50A
Tripping Sensitivity (Residual Current): 30mA
Tripping Curve: C (C50 – suitable for general-purpose loads)
Residual Current Type: AC (detects sinusoidal AC leakage currents)
Breaking Capacity: Likely 6kA (based on standard NB2LE specs)
Main Features:
- Ensures human safety by quickly disconnecting the power in case of leakage or shock
- Provides combined protection against leakage, overload, and short circuit
- Suitable for residential, commercial, and light industrial environments
- 1P+N design disconnects both live and neutral conductors for added safety
