16A B Curve 30mA A Type 6KA 1P+N RCBO (NB3LEG-B16)

The CHINT NB3LEG-B16 RCBO provides dependable combined circuit and residual current protection in a compact format. Designed for domestic and light commercial electrical installations, it helps protect both people and property from electrical faults such as overloads, short circuits and earth leakage.

With a 16 amp current rating, this RCBO is suitable for everyday circuits powering lighting, sockets and general household appliances. The B curve tripping characteristic makes it ideal for standard resistive loads with low inrush currents, ensuring fast and reliable disconnection when faults occur.

This model features Type A residual current protection with a 30 milliamp sensitivity, allowing it to detect both alternating and pulsating DC leakage currents. This makes it well suited to modern electrical environments where appliances with electronic components are commonly used.

Built to perform under demanding conditions, the NB3LEG-B16 offers a 6 kiloamp short-circuit breaking capacity. This ensures the device can safely interrupt high fault currents, helping to prevent damage to wiring and connected equipment.

The 1 pole plus neutral (1P+N) configuration combines overcurrent and earth leakage protection in a single compact unit. It is designed for simple installation on standard DIN-rail systems, making it ideal for consumer units and distribution boards where space is limited.

Whether you are upgrading an existing system or installing new circuits, this CHINT RCBO delivers dependable protection, ease of installation and long-term reliability for a wide range of electrical applications.
