4.5KA/6KA 18mm Width DPN Miniature Circuit Breaker TDM4N

The Talemod TDM4N miniature circuit breaker is designed specifically to safeguard building power systems. It not only provides critical overcurrent and short-circuit protection for all power lines and electrical equipment within a building, but also enables infrequent on-off switching of circuits during normal operation, balancing safety protection with essential control functions.
In terms of applicable circuit conditions, this product is compatible with AC 50/60Hz power supply, can operate stably in lines with a rated voltage of 240V, and has a rated working current of up to 32A. When facing a short-circuit fault, its rated short-circuit breaking capacity covers two specifications: 4.5KA and 6KA, which can effectively cut off the fault current and prevent the accident from expanding.
In terms of design and performance, the Talemod TDM4N adopts a modular structure, facilitating subsequent installation, maintenance, and system expansion. It strictly adheres to the IEC60898-1 international standard to ensure product quality and safety compliance. Furthermore, it offers stable and reliable performance, precise and sensitive protection features, and a compact, space-saving design. It is particularly suitable for lighting distribution circuits in industrial and commercial scenarios, providing a strong guarantee for power safety.
