CHINT เซอร์กิตเบรกเกอร์กันไฟดูด (RCBO) รุ่น NB3LEU 1P+N 30mA 10kA พิกัดไฟ 6A-50A

Rated residual operating current

IΔn = 30 mA : additional protection in the case of direct contact.

Tripping class

AC class – Tripping is ensured for sinusoidal, alternating currents, whether they are quickly applied or increase slowly.

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 & Short-Circuits; protection for resistive and inductive loads with low inrush current.
