YAZAKI 73FD-1200 DC Low Voltage Circuit Breaker

The YAZAKI 73FD-1200 UNMP is a DC low‑voltage circuit breaker rated for 500V DC and 120A, built to interrupt fault currents and protect circuits in DC power systems. With a 120A interrupt rating and a 500V DC maximum, it serves as overcurrent protection in applications such as DC distribution panels, industrial equipment, and battery‑backed power arrangements. The 73FD-1200 designation identifies the exact Yazaki model, while UNMP denotes the specific variant used for sourcing and installation within the 73FD family. Use this breaker to safeguard circuits powered from DC sources up to 500V, ensuring compatibility with other Yazaki protection devices designed to operate in similar DC networks. Given its DC ratings, ensure integration with wiring and distribution components rated for at least 500V DC and that the installation complies with applicable electrical standards.
