The TBC-3100Z is a high-performance Miniature Circuit Breaker (MCB) engineered to deliver reliable protection for electrical distribution circuits against overload and short-circuit conditions. Featuring a robust thermal-magnetic trip mechanism and compliance with IEC 60947-2 standards, this 3-pole MCB is ideal for demanding commercial and industrial environments where safety and reliability are paramount.
The TBC-3100Z Miniature Circuit Breaker represents a perfect balance of performance, reliability, and safety for three-phase electrical protection applications. Designed with a 100A rated current capacity and 10kA breaking capacity, this MCB provides robust protection for commercial and industrial electrical installations.
Built with a thermal-magnetic trip technology, the TBC-3100Z responds accurately to both sustained overload conditions and sudden short-circuit faults. The Type C tripping curve makes it particularly suitable for circuits with inductive loads, motors, and transformers where inrush currents are common.
The compact modular construction allows for efficient use of distribution board space, while the standard DIN rail mounting ensures quick installation and easy replacement. With an impressive mechanical life of 20,000 cycles and electrical life of 4,000 cycles, the TBC-3100Z delivers long-term reliability and reduced maintenance costs.
Manufactured to meet stringent IEC 60947-2 international standards and carrying CE marking, the TBC-3100Z provides peace of mind for electrical contractors, facility managers, and industrial engineers seeking dependable circuit protection solutions.
Trip Mechanism: The TBC-3100Z employs a thermal-magnetic trip mechanism combining a bimetallic element for overload protection and an electromagnetic coil for instantaneous 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 rated breaking capacity of 10kA at 415V AC, the MCB can safely interrupt fault currents up to 10,000 amperes, providing reliable protection in most commercial and light industrial applications.
Construction: The circuit breaker features a robust thermoplastic housing with high mechanical strength and flame-retardant properties. Internal arc chutes ensure safe arc extinction during fault interruption. Silver alloy contacts provide excellent conductivity and wear resistance.
Mounting: Standard 35mm DIN rail mounting with snap-on mechanism allows for tool-free installation and removal. The modular width of 81mm (approximately 4.5 modules) accommodates three-pole configuration.
Environmental Performance: Designed to operate reliably across a wide temperature range from -35°C to +70°C with relative humidity up to 95%, making it suitable for diverse installation environments. IP20 protection rating ensures safety against solid objects larger than 12.5mm.
Compliance: Fully compliant with IEC 60947-2 international standard for low-voltage switchgear and controlgear. CE marking confirms conformity with European safety, health, and environmental protection standards.
