BY02L-63 RCBO 3KA Residual Current Circuit Breaker with Over-current Protection

Product Overview

• The BY02L-63 series 3kA RCBO (Residual Current Circuit Breaker with Over-current Protection) is a versatile and reliable device designed to protect electrical systems against over-current, short-circuit, and residual current (leakage) faults. With a rated current of up to 63A, it offers multiple pole configurations, including 1P+N, 2P, 3P, 3P+N, and 4P, making it suitable for both single-phase (240V) and three-phase (400V) applications. Operating at a frequency of 50Hz, it meets international standards for safety and performance.
• This RCBO is engineered to automatically disconnect the circuit in the event of an earth fault or leakage current, providing effective protection against electric shock and fire hazards. It operates independently of the power supply and line voltage, ensuring reliable functionality even during voltage fluctuations or external interference. This makes it a dependable solution for both residential and commercial applications where consistent protection is essential.
• The BY02L-63 series is equipped with finger-protected connection terminals, enhancing user safety during installation and maintenance. These terminals prevent accidental contact with live parts, ensuring compliance with safety regulations and providing peace of mind to installers and end-users.
• A built-in indicator window allows for quick and easy status monitoring, streamlining maintenance and troubleshooting. Its compact design saves space in electrical panels, while the high-quality construction ensures durability and long service life under varying environmental conditions.
