The TBC-106M is a high-performance 1-pole miniature circuit breaker engineered to deliver dependable protection against overload and short-circuit conditions in residential and commercial electrical installations. Featuring a proven thermal-magnetic trip mechanism, this compact MCB ensures fast, safe disconnection to protect your electrical circuits and connected equipment. With its 6kA breaking capacity and Type C tripping curve, the TBC-106M is ideal for general-purpose applications including lighting circuits, socket outlets, and distribution boards.
The TBC-106M Miniature Circuit Breaker represents a perfect balance of compact design, reliable performance, and cost-effective protection for low-voltage electrical systems. This 1-pole MCB is specifically designed for distribution applications where space is at a premium and dependable circuit protection is essential.
Utilizing advanced thermal-magnetic trip technology, the TBC-106M provides dual protection: the thermal element guards against sustained overloads, while the magnetic element ensures instantaneous tripping during short-circuit faults. The Type C tripping curve makes it particularly suitable for resistive and inductive loads commonly found in residential and commercial environments.
Built to international quality standards including IEC-60898 and backed by CE, CB CERT, and TÜV certifications, the TBC-106M delivers peace of mind through proven reliability. Its IP20 degree of protection and robust construction ensure long-term performance even in demanding environmental conditions, with an impressive mechanical durability of 20,000 cycles.
Installation is straightforward thanks to standard 35mm DIN-rail mounting, while the clear ON/OFF indicator provides instant visual confirmation of circuit status. Whether you're upgrading an existing installation or designing a new electrical distribution system, the TBC-106M offers professional-grade protection in a compact, user-friendly package.
Trip Mechanism: The TBC-106M employs a thermal-magnetic trip unit that combines two complementary protection technologies. The thermal element uses a bimetallic strip that bends under sustained overload conditions, triggering disconnection when current exceeds rated values for an extended period. The magnetic element provides instantaneous protection against short-circuit currents, typically operating at 5-10 times the rated current (Type C curve characteristic).
Breaking Capacity: With a rated breaking capacity of 6 kA at 240/415V AC, this MCB can safely interrupt fault currents up to 6,000 amperes, making it suitable for most residential and light commercial applications. The breaking capacity is tested and certified according to IEC-60898 standards.
Electrical Characteristics: The device is rated for 6A continuous current at an ambient temperature of up to 70°C. It operates on both 50 Hz and 60 Hz AC networks and is suitable for single-phase 240V or three-phase 415V systems (when used in multi-pole configurations). The rated impulse withstand voltage of 4 kV provides protection against transient overvoltages.
Construction & Materials: The MCB housing is manufactured from high-grade thermoplastic material with flame-retardant properties, ensuring safe operation and compliance with fire safety regulations. Internal contacts are designed for low contact resistance and high arc-quenching capability. The device meets IP20 ingress protection rating, suitable for installation in enclosed distribution boards.
Installation & Mounting: Designed for standard 35mm DIN-rail mounting (EN 60715), the TBC-106M occupies just 18mm (1 module) of panel width, allowing for high-density installations. Terminal connections accommodate conductors up to specified cross-sectional areas, with screw terminals ensuring secure, maintenance-free connections.
