It safeguards against overloads, short-circuits, and residual currents, providing additional 30mA protection in case of direct contact. With A Type tripping for both sinusoidal and pulsed DC residual currents, it’s suitable for resistive and inductive loads. Compatible with auxiliary contacts, shunt release, and over-voltage release add-ons, this RCBO is versatile for complex electrical systems.
Description
The CHINT NB310L-3N-C40 RCBO is a robust 3-pole plus neutral (3P+N) circuit breaker with a 40A rating, designed to provide essential personnel and fire protection in electrical installations. Featuring a C Curve tripping characteristic (5 In-10 In), it effectively shields circuits from overloads, short-circuits, and residual currents, making it suitable for resistive and inductive loads with low inrush currents in TN and IT systems. Its rated residual operating current of 30mA offers additional protection in case of direct contact, while the A Type tripping class ensures reliable action in response to sinusoidal and pulsed DC residual currents.
The NB310L-3N-C40 supports a range of add-on devices, including XF9 auxiliary contacts, S9 shunt release, V9 under-voltage release, and OVT-1 over-voltage release. These accessories provide enhanced control and monitoring options, making it adaptable for residential, commercial, and industrial environments requiring advanced circuit protection. With this RCBO, users gain comprehensive safety features and customizable options to meet complex circuit protection needs.
