The N 554D31 universal dimmer from Siemens is a versatile switching and dimming device designed for controlling resistive, inductive, and capacitive loads. With four outputs, it allows for flexible adaptation to different load types, while the automatic switching between phase-cut and phase-control ensures easy handling. The dimmer is designed for operation at a rated voltage of AC 230 V and a frequency of 50 and 60 Hz. At an ambient temperature of +45 °C, each output can deliver up to 300 VA, while bundling adjacent outputs can achieve a total power of up to 1000 VA. The N 554D31 also features electronic protection against overload, short circuit, and overtemperature, enhancing the safety and longevity of the device. The maintenance-free terminals enable easy installation and connection of various conductor types.

• Automatic adaptation to different load types for optimal performance
• Electronic protection per output against overload and short circuit
• Maintenance-free terminals for easy installation
• Manual operation function for switching and dimming directly at the device
