NB4LE Residual Current Operated Circuit Breaker (Electronic)
NBH8LE Residual Current Operated Circuit Breaker with Over-current Protection (Electronic)
1. General
1. General
1.1 Function Personnel and fire protection: Cable and line protection against overload and short-circuits. 1.2 Selection Rated residual operating current I∆n ＝ 30mA, additional protection in the case of direct contact. RCD Type A RCD Type A is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly or slowly increase. Tripping curve: B curve (3 In-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 In-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
• Protection against risk of fire • Protection against risk of electric shock
• Protection against overload • Protection against short circuit
