Product Overview

The ABB 63NHG00B-690 3ABD0001782​ is a high-breaking-capacity NH00-size low-voltage fuse-link engineered for AC 690 V power distribution and equipment protection. As a ceramic square-body blade fuse carrying the ABB material number 3ABD0001782, the ABB 63NHG00B-690 3ABD0001782​ is rated at 63 A continuous current and provides a phenomenal 120 kA breaking capacity in accordance with IEC 60269-1 and IEC 60269-2. Within the ABB NH-system fuse family, the ABB 63NHG00B-690 3ABD0001782​ is classified under utilization category gG/gL—meaning it delivers full-range protection for both cables (gL) and general equipment (gG), withstanding motor-starting surge currents while still clearing true short-circuits in milliseconds and confining the fault energy inside the fuse body.The defining feature of the ABB 63NHG00B-690 3ABD0001782​ is its dual combination indicator system. Upon fuse operation, a mechanical striker pin ejects from the top of the body while a front-view color-changing window alerts maintenance staff from outside the cabinet—answering the perennial question of “which phase has blown” in seconds rather than minutes. For remote or unattended installations, the internal micro-switch interface of the ABB 63NHG00B-690 3ABD0001782​ can be coupled with an auxiliary micro-switch (such as the 170H0235) to transmit the blown-fuse status to the control room SCADA or alarm system, enabling predictive maintenance and reducing mean-time-to-repair.Physically, the ABB 63NHG00B-690 3ABD0001782​ measures 79 mm (length) × 30 mm (width) × 58 mm (height) and weighs approximately 216 g. Its ceramic square body houses knife-blade contacts that mate directly with standard NH00 fuse bases, while insulated metal live gripping lugs (IMGL) allow safe insertion and extraction—even under live conditions when using the proper FEH extraction tool. Compliant with IEC 60269-1, IEC 60269-2, DIN 43620 and VDE 0636-2, and carrying CE and RoHS markings, the ABB 63NHG00B-690 3ABD0001782​ is the go-to 63 A/690 V protection element for inverter incomers, motor feeder branches, transformer low-voltage outgoing circuits and MCC power distribution—anywhere a reliable, high-interrupting-capacity safety gate is demanded.
