The Phoenix Contact 0903044 is an advanced electronic device circuit breaker designed for optimal protection of 24 V DC load circuits. With a nominal current of 3 A, this circuit breaker features a unique combination of active electronic current limitation and overload shutdown capabilities. This ensures rapid response to overloads, safeguarding your equipment more effectively than traditional switched-mode power supply units. The device is engineered to limit residual current to 1.3 - 1.8 times the nominal current, providing enhanced safety and reliability. It is suitable for DIN rail mounting and is constructed with a robust black housing that meets the UL 94V0 flammability rating. Ideal for industrial applications, this circuit breaker is a reliable choice for maintaining the integrity of your electrical systems.
