Description
The CHINT NB310L-3N-C25 RCBO circuit breaker is a versatile and high-capacity protection device, rated at 25A with a 3-pole plus neutral (3P+N) configuration. It offers advanced personnel and fire safety through effective overload, short-circuit, and residual current protection. Featuring a C Curve tripping characteristic (5 In-10 In), this RCBO is engineered for resistive and inductive loads with low inrush currents, suitable for TN and IT systems. With a 30mA residual operating current, it provides additional protection in case of direct contact, while the Type A tripping class ensures reliable action in response to both sinusoidal and pulsed DC residual currents.
The NB310L-3N-C25 is compatible with a variety of add-on devices, including XF9 auxiliary contacts, S9 shunt release, V9 under-voltage release, and OVT-1 over-voltage release, enabling expanded control and monitoring options for complex installations. Suitable for residential, commercial, and industrial environments, it delivers robust, adaptable protection for demanding circuit applications.
