Features of Residual current operated circuit breaker with over-current protection CHINT NB3LE series
https://chint-sit1.oss-cn-hongkong.aliyuncs.com/uploads/product_user/document_file/file/NB3LE%20catalog.pdf
Rated residual operating current. I∆n = 30 mA: additional protection in the case of direct contact.
Tripping class: AC class – Tripping is ensured for sinusoidal, alternating
currents, whether they be quickly applied or slowly increase. A class -Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly applied or slowly increase.
Tripping curve: B curve (3-5 In) protection and control of the circuits against
overloads and short-circuits; protection for people and big length cables in TN and IT systems.
C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
