Abb TRK56A Class R Fuse Field Replacement

Product DescriptionThe ABB TRK56A is a Class R fuse designed for field replacement in electrical distribution and motor control applications. Class R fuses are current-limiting protective devices that interrupt fault currents quickly, helping to protect downstream equipment from damage. This fuse is installed by licensed electricians and electrical contractors working on panel boards, disconnect switches, motor starters, and similar equipment where Class R-rated overcurrent protection is required.Class R fuses are widely used in commercial and industrial electrical systems. The TRK56A is suited for field service scenarios where a technician is replacing a blown or degraded fuse during routine maintenance or fault remediation. This type of fuse fits standard Class R fuse holders and rejection-style disconnect switches that are common across commercial HVAC, industrial motor control, and general electrical distribution installations.Key FeaturesClass R current-limiting design for fast fault interruptionSuitable for field replacement in disconnect switches and panel applicationsCompatible with Class R rejection-style fuse holdersProvides overcurrent protection for motors, panels, and electrical distribution equipmentCompatibilityDesigned as an OEM-style field replacement Class R fuse for use in standard Class R rejection-style fuse holders and disconnect switches commonly found in commercial and industrial electrical systems.Installation NotesInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse matches the voltage rating, ampere rating, and Class designation of the original device. Never substitute a fuse of a different class or higher amperage rating than the circuit is designed for.Technical SpecificationsFuse Class: Class RUPC: 78316416103Standard InformationBrand: ABBManufacturer Part Number: TRK56A
