CHINT – Circuit Breaker 3P+N, C Curve, A Type, 10A RCBO NB310L-3N-C10

Description

The CHINT NB310L-3N-C10 Circuit Breaker is a 3P+N, C Curve, 10A RCBO designed for comprehensive safety and control in electrical systems, combining personnel and fire protection with cable and line protection against overloads and short circuits. With a rated residual operating current (I∆n) of 30 mA, this breaker provides enhanced protection in cases of direct contact, helping to prevent accidental injuries or fire hazards. Featuring an A-type tripping class, it reliably detects sinusoidal and pulsed DC residual currents, whether they increase slowly or quickly, ensuring prompt response to a wide range of fault conditions. The C Curve tripping profile (5 In-10 In) makes it suitable for protecting circuits with resistive and inductive loads that have low inrush currents. Compatible with TN and IT systems, it provides secure circuit control in diverse environments. Available add-on devices include the XF9 auxiliary contacts, S9 shunt release, V9 under voltage release, and the OVT-1 over voltage release, offering enhanced flexibility and safety for use in applications by Miken Electronics and other industrial applications worldwide.
