25A B Curve 30mA A Type 6KA 1P+N RCBO (NB3LEG‑B25)
The 25A B Curve 30mA A Type 6KA 1P+N RCBO (NB3LEG‑B25) from CHINT delivers dependable circuit protection in a compact, high-performance unit. Designed for domestic and light commercial installations, this device combines overcurrent protection and residual current detection in one module, safeguarding both people and property from faults.
Built to fit a standard DIN rail, the NB3LEG‑B25 protects individual circuits with a 25 amp rating and 30mA residual current sensitivity, giving reliable protection against overloads, short circuits and earth leakage faults. Its Type A characteristic extends sensitivity to both AC and pulsating DC leakage currents, making it ideal for modern electrical loads such as LED lighting, kitchen appliances and power sockets.
The B curve trip response is matched to typical domestic circuit behaviours, balancing nuisance tripping with fast reaction to dangerous overcurrents. With a 6kA breaking capacity it meets recognised safety standards and provides robust performance across living spaces, workshops or office circuits.
Compact and easy to install, the NB3LEG‑B25 occupies only one module space in your consumer unit, so you can expand protection without wasting slots. Its solid build quality from CHINT ensures dependable operation and long service life.
Whether you are updating an existing board or designing a new installation, this RCBO is a smart choice when you want dual protection in one cost-effective unit.
