The TBC-163M is a high-performance 1-pole miniature circuit breaker engineered for dependable protection against overload and short-circuit conditions in low-voltage electrical distribution systems. Featuring a proven thermal-magnetic trip mechanism, this MCB ensures fast and safe disconnection to protect your electrical infrastructure and connected equipment.
The TBC-163M miniature circuit breaker is designed to meet the demanding requirements of modern electrical distribution systems. With its 63A rated current capacity and robust 6 kA short-circuit breaking capability, this MCB provides comprehensive protection for residential, commercial, and light industrial applications.
Built with a thermal-magnetic trip unit, the TBC-163M combines thermal protection against sustained overloads with magnetic protection against short-circuit faults. The Type C tripping characteristic makes it ideal for applications with moderate inrush currents, including lighting circuits, socket outlets, and general distribution.
The compact single-module design (18 mm width) maximizes panel space utilization, while the standard DIN-rail mounting ensures compatibility with existing distribution boards. Clear visual indication of the switching position enhances operational safety and simplifies maintenance procedures.
Trip Mechanism: The TBC-163M employs a thermal-magnetic trip unit technology that provides dual protection. The thermal element responds to sustained overload conditions, while the magnetic element provides instantaneous protection against short-circuit currents.
Type C Tripping Curve: The Type C characteristic is optimized for circuits with moderate inrush currents. Magnetic tripping occurs between 5 and 10 times the rated current, making it suitable for general distribution, lighting, and socket circuits.
Breaking Capacity: With a rated short-circuit breaking capacity of 6 kA at 240/415 V AC, the TBC-163M is suitable for most residential and commercial installations where fault levels are within this range.
Environmental Performance: The MCB operates reliably across a wide temperature range (-35 °C to +70 °C) and humidity conditions (0-95% RH), ensuring consistent performance in diverse installation environments.
Standards Compliance: Fully compliant with IEC 60898 international standards and certified by leading certification bodies including CB, CE, and TÜV, ensuring quality, safety, and global acceptance.
