The TBC-116M is a high-performance 1-pole miniature circuit breaker engineered to deliver dependable protection against overload and short-circuit conditions in residential, commercial, and industrial electrical distribution systems. Featuring a proven thermal-magnetic trip mechanism, this compact MCB ensures fast and safe disconnection to protect your electrical circuits and connected equipment.
The TBC-116M miniature circuit breaker combines robust construction with advanced protection technology to safeguard electrical installations from overload and short-circuit faults. Designed for 1-pole applications with a rated current of 16A, this MCB is ideal for protecting lighting circuits, socket outlets, and general-purpose distribution boards.
Built to IEC-60898 standards, the TBC-116M features a thermal-magnetic trip unit that responds quickly to fault conditions—tripping in less than 0.1 seconds during short-circuit events. The Type C tripping curve makes it particularly suitable for circuits with moderate inrush currents, such as lighting and general power distribution.
With its compact single-module design (18 mm width), the TBC-116M maximizes space utilization in distribution boards while maintaining easy accessibility for maintenance and operation. The clear ON/OFF indicator provides instant visual confirmation of the breaker status, enhancing operational safety and convenience.
Trip Mechanism: The TBC-116M employs a dual thermal-magnetic trip mechanism. The thermal element provides time-delayed protection against sustained overloads, while the magnetic element delivers 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 (In), making it ideal for general distribution, lighting, and socket circuits.
Breaking Capacity: With a rated short-circuit breaking capacity of 6 kA at 240/415V AC, the TBC-116M provides adequate protection for most residential and light commercial installations.
Electrical Ratings: Suitable for both single-phase (240V) and three-phase (415V) systems operating at 50/60 Hz. Rated impulse withstand voltage of 4 kV ensures protection against transient overvoltages.
Environmental Protection: IP20 degree of protection guards against solid objects larger than 12.5 mm. The wide operating temperature range (-35°C to +70°C) ensures reliable performance in diverse environmental conditions.
Durability: Engineered for long service life with mechanical durability of 20,000 operations and electrical durability of 4,000 operations under load conditions.
