The TBC-216M 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-216M combines robust construction with ease of installation on standard 35mm DIN rails.
The TBC-216M 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 operation and preventing damage to connected equipment and wiring systems.
Engineered with thermal-magnetic tripping technology, the TBC-216M 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 lighting circuits, distribution boards, and equipment with inductive loads.
With a rated current of 16A and breaking capacity of 6kA at 415V AC, this MCB provides robust protection for residential and commercial installations. The compact 2-module design (36mm width) allows for efficient use of distribution board space, while the toggle control mechanism ensures simple manual operation for circuit isolation during maintenance.
Built to withstand demanding environmental conditions, the TBC-216M 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 costs.
Tripping Technology: The TBC-216M employs advanced thermal-magnetic tripping technology. The thermal element responds to sustained overload currents by heating a bimetallic strip that bends and triggers the trip mechanism. The magnetic element provides instantaneous protection against short-circuits by using electromagnetic force to release the trip mechanism when fault currents exceed predetermined thresholds.
Type C Tripping Curve: The Type C characteristic provides tripping between 5 and 10 times the rated current (In), making it ideal for circuits with moderate inrush currents such as fluorescent lighting, small motors, and transformers. This curve balances protection sensitivity with nuisance tripping prevention.
Breaking Capacity: With a 6kA breaking capacity (Icn), the TBC-216M can safely interrupt fault currents up to 6,000 amperes at rated voltage, making it suitable for most residential and commercial applications where prospective short-circuit currents are within this range.
Construction & Materials: The MCB features a thermoplastic housing with high arc resistance, silver alloy contacts for reliable switching performance, and a DIN rail mounting clip for secure installation. The internal arc chute system effectively extinguishes arcs during fault interruption.
Standards Compliance: Fully compliant with IEC 60898-1 international standard for MCBs for household and similar installations. Certified by CB CERT, CE marked for European conformity, and TÜV tested for quality assurance.
