product detail

Product Overview

  • The BY05HL-40 series 6kA RCBO (Residual Current Circuit Breaker with Over-current Protection) is an updated, high-performance device engineered for comprehensive electrical safety. With a rated current of up to 40A and a 1P+N configuration, it operates at 230V and a frequency of 50Hz, making it ideal for residential and commercial applications. Its advanced design and compact 18mm width make it a modern and efficient solution for protecting electrical systems.
  • This RCBO provides over-current, short-circuit, and residual current (leakage) protection, automatically disconnecting the circuit when faults are detected. This ensures user and equipment safety by reducing risks of electric shocks and fire hazards. The device features a built-in indicator window for real-time monitoring of its operational status, enhancing ease of use and simplifying maintenance.
  • The BY05HL-40 incorporates double breaker points and a current-limiting contact system, which improves its breaking capacity and reduces the impact of high short-circuit currents. Additionally, its magnetic blowout arc-control device enhances the product's arc-extinguishing capability, ensuring reliable operation under high-stress conditions. These features extend the service life of the breaker and improve overall performance.
  • Constructed with a flame-retardant casing, the RCBO is designed for durability and enhanced safety, providing excellent resistance to heat and environmental stresses. Its 18mm width allows for efficient space utilization in electrical panels, making it an excellent choice for compact installations.
