Overview

The Littelfuse 1PH3P18MM (SKU: 1PH3P18MM) is a UL 508 Listed POWR Busbar system designed for safe and efficient electrical power distribution in industrial and commercial applications. This compact busbar system significantly reduces redundant wire terminations, streamlining panel design and enhancing safety. Its 60mm length is precisely cuttable to meet specific application needs, offering exceptional installation flexibility. Key features include a touch-safe design for technician safety during fuse replacement and 35mm DIN-rail mountability. The 1PH3P18MM is compatible with Littelfuse dead front fuse holders such as LFPSM, LFPSC, LPSM, LPSC (600V), and LPHV (1000V). Available in 1-phase configurations with an 18mm² cross-sectional area, it supports various current ratings. The 18mm² version handles up to 80A when end-fed and 160A when center-fed. For higher voltage applications, the 1-phase 18mm² version is rated for 1000V DC up to 160A when center-fed. Constructed from high-quality copper for excellent conductivity and thermal management, the 1PH3P18MM meets SCCR standards of 10kA, or 100kA when protected by Class J fuses (175A max for 18mm²). This makes it ideal for motor control centers, power distribution panels, renewable energy systems, and control cabinets. The system is RoHS-compliant and lead-free. Its modular design facilitates easy integration, and the cut-to-size capability minimizes waste and installation time. Littelfuse's commitment to innovation and reliability ensures the 1PH3P18MM meets high performance and safety standards.
