TBC-120M Miniature Circuit Breaker (MCB) 1P 20A 6kA

Trip Mechanism: The TBC-120M employs a thermal-magnetic trip mechanism 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 curve is optimized for general-purpose applications, with magnetic tripping occurring between 5 and 10 times the rated current. This makes it suitable for circuits with moderate inrush currents such as lighting and socket outlets.

Breaking Capacity: With a rated short-circuit breaking capacity of 6 kA at 240/415V AC, the TBC-120M provides adequate protection for typical residential and commercial installations.

Electrical Ratings: Rated for operation at 240/415V AC, 50/60 Hz, with a rated impulse voltage withstand of 4 kV, ensuring robust performance in standard distribution networks.

Durability: Engineered for long service life with mechanical durability of 20,000 operations and electrical durability of 4,000 operations under load conditions.

Environmental Performance: Designed to operate reliably across a wide temperature range from -35°C to +70°C, with humidity tolerance up to 95% relative humidity.
