product detail

Product Features 

  • The BYF-63 series 10kA type B residual current device (RCD) is an advanced circuit breaker designed to provide comprehensive residual current protection. It represents a significant upgrade from Type A RCCBs, offering enhanced detection and protection capabilities. This device is capable of safeguarding against AC and pulsing DC residual currents (Type A), compound residual currents (Type F), as well as smoothing DC and high-frequency residual currents up to 1kHz (Type B). Its advanced design makes it particularly suitable for circuits containing rectifiers, inverters, and other components that generate complex leakage currents in DC loop systems.
  • The BYF-63 series RCD can effectively detect and protect against leakage currents caused by DC circuits, ensuring the safety of both equipment and personnel. With a rated current of up to 63A, it is available in two configurations: 1P+N, supporting 230/240V, and 3P+N, supporting 400/415V. The device is engineered to handle challenging electrical environments, providing reliable and consistent performance.
  • The BYF-63 series RCD features a robust construction with a durable housing, ensuring long-lasting performance and safety. Its advanced residual current detection capabilities and high breaking capacity of 10kA make it an ideal choice for industrial, commercial, and residential applications where comprehensive residual current protection is required.
