The TBC-206M is a high-performance 2-pole miniature circuit breaker engineered to deliver dependable protection against overload and short-circuit faults in low-voltage electrical distribution systems. Featuring thermal-magnetic tripping technology with Type C characteristic and 6kA breaking capacity, this MCB ensures optimal safety and reliability for residential, commercial, and light industrial installations. Compliant with IEC 60898-1 standards and certified by leading international bodies, the TBC-206M combines robust construction with precise protection characteristics.
The TBC-206M Miniature Circuit Breaker represents a reliable solution for protecting electrical circuits in diverse applications. This 2-pole MCB is specifically designed to safeguard against both overload conditions and short-circuit faults, ensuring continuous protection of your electrical infrastructure.
Engineered with thermal-magnetic tripping technology, the TBC-206M combines a bimetallic thermal element for overload protection with an electromagnetic release for instantaneous short-circuit protection. The Type C tripping characteristic makes it particularly suitable for circuits with moderate inrush currents, including general lighting, heating systems, and motor-driven equipment.
With a rated voltage of 415V AC and a breaking capacity of 6kA, this MCB provides robust protection for standard low-voltage distribution networks. The compact 2-module design optimizes space utilization in distribution boards while maintaining full functionality and safety standards.
Built to withstand demanding environmental conditions, the TBC-206M operates reliably across a temperature range of -35°C to +70°C and humidity levels up to 95%. Its robust construction ensures 20,000 mechanical operations and 4,000 electrical operations, delivering long-term reliability and reduced maintenance requirements.
Tripping Characteristics:
The TBC-206M features Type C tripping characteristics, designed to trip between 5 and 10 times the rated current (In). This makes it ideal for circuits with moderate inrush currents such as fluorescent lighting, small motors, and transformers. The thermal-magnetic mechanism ensures precise and reliable operation across the full range of fault conditions.
Breaking Capacity:
With a rated breaking capacity of 6kA at 415V AC, the TBC-206M is suitable for most residential and commercial installations where fault levels are within this range. The breaking capacity represents the maximum fault current the MCB can safely interrupt without damage.
Installation and Mounting:
The MCB is designed for standard 35mm DIN rail mounting, ensuring quick and secure installation in distribution boards and enclosures. The 2-pole configuration occupies 36mm (2 modules) of rail space, allowing efficient use of panel space. The toggle control mechanism provides clear ON/OFF indication and manual switching capability.
Protection Coordination:
The TBC-206M can be effectively coordinated with upstream and downstream protective devices to ensure selective tripping and minimize disruption during fault conditions. Its fast tripping time of less than 0.1 seconds provides rapid fault clearance, reducing the risk of equipment damage and electrical hazards.
Standards Compliance:
Manufactured in accordance with MS IEC 60898-1 standards, the TBC-206M meets stringent international requirements for miniature circuit breakers. The product carries CB certification, CE marking, and TÜV approval, demonstrating compliance with safety, performance, and quality standards recognized worldwide.
