Size label: NXB631PD25 indicates the specific size/configuration within the product line. Trip characteristics: Dtype trip curve options available for applications with moderate to inrush currents typical of motor and inductive loads. Performance: Designed for repeatable operation and clear trip behavior across the available ratings. Typical applications Lighting and small power distribution in residential and commercial buildings where compact protection devices are needed. Protection of motor circuits, pumps, and compressors that produce inrush currents, using Dtype trip ratings to avoid nuisance tripping. Panel feed and branch circuit protection in control panels and distribution boards for machinery and equipment. Selection tips Match the pole configuration to your circuit: choose 1P for single live conductor, 1P+N when neutral switching is needed, and 2P for twopole circuits. Select the Drating that accommodates the expected inrush and starting currents of connected equipment while providing reliable overcurrent protection. Use the model list to identify the exact breaker required for replacements or installations. This product line delivers a compact, straightforward solution for overcurrent protection across a wide range of lowvoltage applications, with multiple pole configurations and Dcharacteristic trip ratings to meet common installation needs.
