Model No: DZ47LE-63 Series
DZ47LE-63 Series Residual Current Circuit Breaker
The DZ47LE-63 series residual current circuit breaker is created by integrating a high-performance DZ47-63 miniature circuit breaker with a specialized residual current trip unit. This device functions as a current-operated, electronic-type residual current circuit breaker. Its core composition includes four main components: a zero-sequence current transformer ($\text{ZCT}$), an electronic component board, the dedicated residual current trip unit, and the foundational circuit breaker which provides essential overload and short-circuit protection.

The DZ47LE-63 series Residual Current Circuit Breaker (RCCB/RCBO) is created by perfectly integrating a high-performance DZ47-63 miniature circuit breaker with a specialized residual current trip unit. This Residual Current Circuit Breaker (RCCB/RCBO) functions as a current-operated, electronic-type circuit breaker. The core value of this Residual Current Circuit Breaker (RCCB/RCBO) lies in its provision of comprehensive safety assurance.The primary composition of this Residual Current Circuit Breaker (RCCB/RCBO) includes a zero-sequence current transformer ($text{ZCT}$), an electronic component board, the dedicated residual current trip unit, and the foundational circuit breaker providing Integrated Overcurrent Protection. Integrated Overcurrent Protection signifies the inclusion of both overload and short-circuit protection features. Integrated Overcurrent Protection ensures that the wiring is protected from high current damage. The design philosophy of this Residual Current Circuit Breaker (RCCB/RCBO) is to unify Integrated Overcurrent Protection with residual current functionality.The DZ47LE-63 Residual Current Circuit Breaker (RCCB/RCBO) is suitable for AC $50text{Hz}$ (or $60text{Hz}$) circuits with a rated voltage of $400text{V}$ and single-phase $230text{V}$, and rated currents from $3text{A}$ to $63text{A}$. Its most critical function is Earth Leakage Protection and electric shock protection. Earth Leakage Protection is key to ensuring personnel safety. Earth Leakage Protection effectively prevents equipment accidents caused by leakage currents. The model of this Residual Current Circuit Breaker (RCCB/RCBO) with a rated residual operating current of $30text{mA}$ provides direct protection against personal electric shock, representing the highest standard of Earth Leakage Protection.This Residual Current Circuit Breaker (RCCB/RCBO) simultaneously features Earth Leakage Protection, electric shock protection, overload protection, and short-circuit protection. The latter two fall under the category of Integrated Overcurrent Protection. Integrated Overcurrent Protection ensures the safe interruption of the circuit under fault conditions. The combination of Integrated Overcurrent Protection and Earth Leakage Protection is the unique advantage of the DZ47LE-63 Residual Current Circuit Breaker (RCCB/RCBO). Integrated Overcurrent Protection is the baseline circuit protection, while Earth Leakage Protection is the guarantee of personal safety. Every Residual Current Circuit Breaker (RCCB/RCBO) is rigorously tested to ensure the reliability of both Integrated Overcurrent Protection and Earth Leakage Protection.Users can also request the addition of an overvoltage protection function, further enhancing the protective scope of this Residual Current Circuit Breaker (RCCB/RCBO). Earth Leakage Protection safeguards not only people but also connected equipment. Integrated Overcurrent Protection eliminates the need for separate components to achieve complete circuit protection. The widespread application of this Residual Current Circuit Breaker (RCCB/RCBO) reflects the high market importance placed on both Earth Leakage Protection and Integrated Overcurrent Protection. We are dedicated to providing the most reliable Residual Current Circuit Breaker (RCCB/RCBO), featuring superior Earth Leakage Protection and precise Integrated Overcurrent Protection.
