Special features
Non-indicating, High in-rush current motor protection
Feature: Non-indicating design keeps a clean panel appearance and minimizes misinterpretation during maintenance. This reduces maintenance overhead and speeds up inspections, particularly in crowded control panels. Application: motor control centers and cabinet installations where quick, non-intrusive protection is needed. Feature: 300 A amperage with 200 kAIC interrupt rating provides strong fault protection and rapid isolation of faults. This minimizes damage to drives and wiring and lowers repair costs. Application: high-inrush motor starts in pumps, conveyors, and crushers. Feature: Voltage ratings of 250 Vac and 125 Vdc offer design flexibility across mixed voltage panels. This improves compatibility with standard AC motor circuits and DC control systems. Application: general-purpose motor protection in mixed-voltage industrial environments. Feature: Class RK1 construction with electrically isolated end caps improves safety during installation and servicing. This reduces arc risk and simplifies wiring in retrofit projects. Application: Edison fuse bases and legacy equipment upgrades. Feature: RoHS compliant with UL Listed and CSA Certified credentials provide regulatory assurance and supply-chain reliability. This supports audits and procurement in highly regulated industries. Application: global manufacturing facilities and OEMs requiring compliant components. Feature: Standard packaging and single-fuse quantity streamline stocking and quick replacement. This enables faster procurement cycles and consistent field performance in service programs and new builds.
