The TBC-416M miniature circuit breaker represents a robust solution for protecting electrical circuits in diverse environments. Its 4-pole design ensures complete protection across all phases and the neutral conductor, making it particularly suitable for three-phase installations.

Equipped with thermal-magnetic trip technology, the TBC-416M provides dual-mode protection: the thermal element guards against sustained overloads, while the magnetic element responds instantly to short-circuit conditions. The Type C tripping characteristic makes this MCB especially well-suited for circuits with moderate inrush currents, such as those powering fluorescent lighting, small motors, and transformers.

Built to withstand demanding conditions, the TBC-416M operates reliably across a wide temperature range and maintains performance in humidity levels up to 95%. Its DIN rail mounting system ensures straightforward installation in standard distribution boards, while the toggle control mechanism provides clear manual operation and position indication.

With comprehensive international certifications including CE, CB, and TÜV, the TBC-416M meets stringent safety and performance standards, giving installers and end-users confidence in its protective capabilities.

Trip Mechanism: The TBC-416M employs a proven thermal-magnetic trip mechanism. The thermal element consists of a bimetallic strip that bends under sustained overcurrent conditions, triggering the trip mechanism when the rated current is exceeded for a prolonged period. The magnetic element uses an electromagnetic coil that produces instantaneous tripping when short-circuit currents are detected.

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 inductive loads. This curve balances sensitivity to fault conditions with immunity to normal inrush currents experienced during equipment startup.

Breaking Capacity: With a rated breaking capacity of 6kA at 415V AC, the TBC-416M can safely interrupt fault currents up to 6,000 amperes, suitable for most residential and commercial installations where prospective short-circuit currents are within this range.

Construction: The circuit breaker features a robust thermoplastic housing with silver-plated contacts to ensure low contact resistance and long service life. The arc chutes are designed to rapidly extinguish electrical arcs during interruption, protecting internal components and ensuring reliable operation.

Installation: Designed for standard 35mm DIN rail mounting, the TBC-416M integrates seamlessly into modern distribution boards. The 72mm width (equivalent to 4 modular units) accommodates the 4-pole configuration while maintaining compact installation footprint.
