The TBC-410M miniature circuit breaker represents a robust solution for protecting electrical circuits against overload and short-circuit conditions in demanding environments. With its 4-pole design, this MCB provides simultaneous protection across all phases and the neutral conductor, making it particularly suitable for three-phase installations.

Built with thermal-magnetic trip technology, the TBC-410M combines a bimetallic element for overload protection with an electromagnetic release for instantaneous short-circuit protection. The Type C tripping characteristic makes it ideal for circuits with moderate inrush currents, such as lighting circuits, small motors, and general power distribution.

Designed for professional installation, the breaker mounts securely on standard 35mm DIN rails and features a compact footprint that maximizes panel space utilization. Its robust construction ensures reliable performance across a wide temperature range, while multiple international certifications guarantee compliance with global electrical safety standards.

Tripping Characteristics: The Type C tripping curve provides instantaneous magnetic tripping between 5 and 10 times the rated current, making it suitable for circuits with moderate inrush currents. The thermal element responds to sustained overloads, while the magnetic element provides rapid protection against short circuits.

Breaking Capacity: With a rated breaking capacity of 6kA at 415V AC, the TBC-410M is designed to safely interrupt fault currents in typical residential and commercial installations. The breaking capacity is sufficient for most distribution board applications where prospective fault currents are within this range.

Construction: The circuit breaker features a thermoplastic housing with silver-plated contacts for reliable electrical performance. The toggle mechanism provides clear ON/OFF indication and manual trip functionality. Internal arc chutes safely extinguish arcs during interruption.

Durability: Rated for 20,000 mechanical operations and 4,000 electrical operations at rated current, the TBC-410M is built for long-term reliability in professional installations. The robust mechanism maintains consistent performance throughout its operational life.

Environmental Performance: The wide operating temperature range of -35°C to +70°C ensures reliable operation in diverse climatic conditions, from cold storage facilities to warm industrial environments. The IP20 rating provides protection against solid objects larger than 12.5mm.
