Littelfuse LHR0000H - Used as in-line protection for fluorescent fixtures, the Littelfuse LGR and LMF series fuses and LHR holder offer increased safety and reliability to lighting systems. On a 277 volt system, a fault occurring in an un-fused fixture could take out the entire branch circuit affecting up to 100 fixtures. This could cause safety problems as well as shut down operations. By individually fusing fixtures, these problems will be avoided. The added benefits of this is the ability to quickly identify the problem fixture and reduce the repair time. Fuse holders are rated up to 10 amperes at 300 volts and are equipped with 7” 18 AWG leads. Order part number LHR 000 for two leads, and part number LHR 001 for one lead and one terminal for insertion of 18 AWG ballast lead.

Overview

The Littelfuse LHR0000H fuse holder provides critical in-line protection for fluorescent lighting fixtures, ensuring enhanced safety and reliability in industrial and commercial environments. Designed to prevent cascading electrical failures, this fuse holder isolates faults to individual fixtures, preventing entire branch circuits from shutting down. On a 277V system, a single un-fused fault could disrupt up to 100 fixtures, causing operational downtime and safety hazards. By individually fusing each fixture, the LHR0000H eliminates this risk, allowing for rapid fault identification and minimizing repair time. Rated for up to 10 amperes at 300 volts, the LHR0000H is engineered for demanding lighting applications where uninterrupted operation is essential. Its 7-inch 18 AWG leads provide flexible, secure connections, while the fuse holder accommodates Littelfuse LGR and LMF series fuses for reliable performance. Two ordering options are available: LHR 000 includes two leads, and LHR 001 provides one lead and one terminal for inserting an 18 AWG ballast lead. This flexibility ensures compatibility with a wide range of fluorescent fixture configurations. Ideal for manufacturing plants, warehouses, commercial buildings, and other facilities where lighting reliability is critical, the LHR0000H delivers targeted protection that enhances operational efficiency and reduces maintenance costs. Its robust design and compliance with industry standards make it a trusted solution for maintaining safe and efficient lighting infrastructure.
