4P 40A DZ47LE 400V~ Residual Current Circuit Breaker with overcurrent and Leakage Protection

Thermal Circuit BreakersThis link is for 4P 40A C type only.Residual current type: AC typeDZ47LE is suitable for AC 50/60Hz rated voltage 230V single-pole two-wire, two-pole or 400V three-pole, three-pole four-wire, four-pole, rated current up to 63A. It can be used as overload and short-circuit protection for lines and motors. It can also be used for infrequent line switching and infrequent motor starting, in compliance with IEC61009 standards.DZ47LE residual current operated circuit breaker with overcurrent protection ()1. ApplicationPersonnel and fire protectionCable and line overload and short-circuit protection2. General rules for selection:a. Rated residual operating currentAt 30 mA: Additional protection against direct contact At 300 mA: Preventive fire protection against earth fault currentb. TrippingAC Category - Ensures tripping on sinusoidal alternating current, whether applied quickly or increasing slowly.c. Tripping curveC-curve (5-10 In) protects and controls circuits against overload and short circuit; protects resistive and inductive loads with low inrush current.D curve (10-14 In) protects and controls circuits against overloads and short circuits; protects circuits that supply loads with high inrush currents when the circuit is closed (LV/LV , fault lamps).
