TBC-125M Miniature Circuit Breaker (MCB) 1P 25A 6kA

Trip Mechanism: The TBC-125M employs a thermal-magnetic trip unit that combines a bimetallic strip for overload protection with an electromagnetic coil for short-circuit protection. The Type C tripping curve provides tripping at 5-10 times the rated current, making it ideal for resistive and inductive loads with moderate switching surges.

Breaking Capacity: With a rated short-circuit breaking capacity of 6 kA at 240/415V AC, this MCB is suitable for most residential and commercial applications where fault levels are within this range.

Electrical Characteristics: Rated for operation at 240V AC (single-phase) or 415V AC (in multi-pole configurations), with a rated impulse withstand voltage of 4 kV. The device operates at standard power frequencies of 50/60 Hz.

Environmental Performance: Designed for reliable operation across a wide temperature range from -35°C to +70°C, with humidity tolerance up to 95% relative humidity. IP20 degree of protection ensures safe operation in standard indoor electrical enclosures.

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