CHINT – Circuit Breaker 3P+N, C Curve, A Type, 20A RCBO NB310L-3N-C20
The CHINT NB310L-3N-C20 is a 3P+N RCBO circuit breaker with a C Curve tripping characteristic, rated at 20A. It provides essential personnel and fire protection, guarding against overloads, short-circuits, and residual currents, with an additional 30mA protection level for direct contact scenarios. The A Type tripping class ensures reliable response to both sinusoidal and pulsed DC residual currents. Suitable for resistive and inductive loads, it supports various add-ons like auxiliary contacts, shunt release, and over-voltage release for comprehensive circuit management.
Description
The CHINT NB310L-3N-C20 RCBO circuit breaker is a high-performance 3-pole plus neutral (3P+N) protection device designed for personnel and fire safety in electrical installations. Rated at 20A, it features a C Curve tripping characteristic (5 In-10 In) for effective protection against overloads, short-circuits, and residual currents, ideal for resistive and inductive loads with low inrush currents. This RCBO is designed with a Type A tripping class, offering rapid response to both sinusoidal and pulsed DC residual currents, and an additional protection level of 30mA to safeguard against direct contact, making it a reliable choice for TN and IT systems.
Engineered for flexibility and enhanced circuit management, the NB310L-3N-C20 is compatible with various add-on devices such as XF9 auxiliary contacts, S9 shunt release, V9 under-voltage release, and OVT-1 over-voltage release. These accessories allow for expanded monitoring and control capabilities, making it adaptable to complex circuit requirements in residential, commercial, and industrial settings.
