Description
The CHINT NB3LEG-C20 Type A Residual Current Operated Circuit Breaker with Over-current Protection (RCBO) is a highly effective electrical safety device designed to safeguard residential and commercial electrical systems. With a rated current of 20A, this single-pole plus neutral (1P+N) circuit breaker offers robust protection against electrical hazards, overloads, and short circuits.
Featuring a rated residual operating current (I∆n) of ≤ 30 mA, this RCBO provides essential additional protection against electric shock in the event of direct contact with live parts. Its 6kA short-circuit breaking capacity ensures reliable performance during fault conditions, enhancing the safety and integrity of electrical installations.
The device is equipped with both AC Class and A Class tripping capabilities, allowing it to respond effectively to sinusoidal alternating currents. The AC Class guarantees tripping for both rapidly applied and slowly increasing currents, while the A Class accommodates sinusoidal alternating residual currents and pulsed DC residual currents, ensuring versatile protection for a wide range of electrical devices.
This model features a C Curve (5-10 In) characteristic, making it ideal for circuits with inductive and resistive loads, particularly those with low inrush currents. It provides effective overload and short-circuit protection, which is crucial for ensuring the safety of wiring systems, especially in TN and IT networks. The CHINT NB3LEG-C20 is a dependable choice for enhancing electrical safety across diverse applications, ensuring peace of mind for users and maintenance personnel alike.
