NB8LE-63M
DZ158LE 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 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 curves: C curve (5-10In) protection for resistive and inductive loads with low inrush current. D curve(10-16In) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
• Protection against risk of fire • Protection against risk of electric shock
• Protection against overload • Protection against short circuit
