The TBC-363M is a high-performance 3-pole miniature circuit breaker engineered for reliable overload and short-circuit protection in AC power distribution systems. Featuring advanced thermal-magnetic tripping technology and a robust 10kA breaking capacity, this MCB delivers dependable circuit protection for residential, commercial, and light industrial applications. Compliant with IEC 60898 standards and CE marked, the TBC-363M ensures safety and reliability in demanding electrical environments.
The TBC-363M Miniature Circuit Breaker represents a professional-grade solution for three-phase electrical protection in modern power distribution systems. This 3-pole MCB combines proven thermal-magnetic tripping technology with a robust 10kA breaking capacity, making it suitable for applications where reliable circuit protection is critical.
Designed to meet the rigorous requirements of IEC 60898 standards, the TBC-363M features a Type C tripping curve that makes it particularly well-suited for circuits with inductive loads, motors, and transformers commonly found in commercial and light industrial settings. The 63A rated current capacity provides ample power handling for demanding applications while maintaining compact dimensions.
The circuit breaker's thermal-magnetic mechanism provides dual protection: the thermal element guards against sustained overloads, while the magnetic element offers instantaneous protection against short-circuit conditions. This combination ensures comprehensive circuit protection and helps prevent equipment damage and electrical hazards.
Built for durability and longevity, the TBC-363M offers exceptional mechanical endurance with 20,000 operating cycles and 4,000 electrical cycles. The standard DIN rail mounting system enables rapid installation in distribution boards and electrical panels, while the compact 3-module width optimizes valuable panel space.
Tripping Technology: The TBC-363M employs thermal-magnetic tripping technology, combining a bimetallic thermal element for overload protection with an electromagnetic release for short-circuit protection. The Type C characteristic provides tripping at 5-10 times the rated current, making it ideal for circuits with moderate inrush currents.
Breaking Capacity: With a 10kA breaking capacity at 415V AC, this MCB can safely interrupt fault currents up to 10,000 amperes, providing robust protection in most commercial and light industrial installations.
Electrical Ratings: Rated for 415V AC operation at 50/60 Hz with a nominal current of 63A, the TBC-363M is designed for three-phase AC network applications. The 3-pole configuration ensures simultaneous disconnection of all three phases during fault conditions.
Environmental Performance: The circuit breaker operates reliably across a wide temperature range from -35°C to +70°C and can withstand relative humidity levels up to 95%, making it suitable for diverse installation environments. The IP20 protection rating provides protection against solid objects larger than 12.5mm.
Mechanical Construction: The robust housing and internal mechanism are engineered for long service life, with mechanical durability rated at 20,000 cycles and electrical durability at 4,000 cycles. The toggle control mechanism provides clear ON/OFF indication and reliable manual operation.
Standards Compliance: Manufactured in accordance with IEC 60898 international standards and bearing CE marking, the TBC-363M meets stringent safety and performance requirements for miniature circuit breakers in low-voltage applications.
