The Littelfuse LFPHV3PAK is a multi-pole assembly kit designed to create 3-pole fuse holder configurations from single-pole LFPHV series fuse holders. This kit is specifically engineered for use with 1000 Vdc, 10x38mm (midget style) dead-front fuse holders, making it suitable for isolating photovoltaic module strings during maintenance.
The assembly kit allows for the creation of robust fuse holder units with a maximum voltage rating of 1000 Vdc and an ampere rating of 30 A. The fuse holders themselves are constructed from thermoplastic material with a UL94 V-0 flammability rating, ensuring self-extinguishing properties for safety. The terminal type is a pressure plate, designed for secure wire connections with a specified torque range.
This accessory kit is ideal for applications requiring reliable and safe isolation of solar PV strings. It meets UL requirements for 1000 Vdc solar fuse protection and offers features like finger-safe design and DIN rail mountability for ease of installation and personnel safety. The kit facilitates the assembly of multi-pole fuse holder units without the need for specialized tools.
The LFPHV3PAK is rated for 1000Vdc operation with an indication voltage range of 400-1000Vdc.
The LFPHV3PAK is rated for 30A continuous current.
The SCCR rating is 33kA.
It uses pressure plate terminals.
It accepts 18-8 AWG (0.75-10 mm²) and 6-4 AWG wire sizes.
It mounts on a 35mm DIN rail.
The housing is thermoplastic with UL94 V-0 self-extinguishing rating.
