The TBC TL-463 Residual Current Circuit Breaker is specifically designed to protect three-phase electrical distribution systems from dangerous earth-leakage currents. This 4-pole RCCB continuously monitors the electrical circuit and automatically disconnects power when it detects a leakage current exceeding 30mA, preventing electric shock injuries and reducing fire risks.
Built with electromechanical trip technology, the TL-463 offers superior reliability and does not require external power to operate. The device features instantaneous tripping characteristics, responding in less than 0.2 seconds at rated sensitivity and less than 0.04 seconds at 5 times rated sensitivity, ensuring rapid protection when needed most.
Designed for professional electrical installations, this RCCB is ideal for commercial buildings, industrial facilities, and power distribution systems where three-phase power is utilized. The robust construction ensures long service life with 10,000 mechanical cycles and 4,000 electrical cycles, while the IP20 protection rating makes it suitable for standard indoor electrical enclosures.
Installation is straightforward with standard DIN rail mounting, and the compact 70mm width allows for efficient use of panel space. The integrated TEST button enables regular functional testing to verify proper operation, supporting preventive maintenance programs and ensuring continuous protection reliability.
Operating Principle: The TL-463 operates on the principle of differential current detection. An internal toroidal transformer continuously monitors the balance between phase and neutral currents. When an earth-leakage fault occurs, the imbalance exceeds the 30mA threshold, triggering the electromechanical trip mechanism to disconnect all poles simultaneously.
Trip Unit Technology: The electromechanical trip unit does not require auxiliary power, making it inherently fail-safe. The Type AC classification means the device responds to alternating sinusoidal residual currents, suitable for standard AC loads.
Breaking Capacity: With a 10kA breaking capacity at 415V AC, the TL-463 can safely interrupt high fault currents, providing comprehensive protection in demanding industrial environments.
Tripping Characteristics: At nominal sensitivity (30mA), the device trips in less than 0.2 seconds. At 5 times nominal sensitivity (150mA), tripping occurs in less than 0.04 seconds, ensuring rapid disconnection during serious fault conditions.
Environmental Performance: The wide operating temperature range of -35°C to +70°C and humidity tolerance up to 95% make the TL-463 suitable for diverse installation environments, including locations with temperature variations and moderate humidity.
Standards Compliance: Manufactured in accordance with IEC 60898-1 international standards and certified by TÜV, CE, and CB, ensuring compliance with global safety and performance requirements.
