Selection of the Fuse and Holder Solution

Littelfuse provides a set of questions to determine what fuse and holder solution is best for you:

Will the fuse need to be accessible for replacement?
How often will the fuse need to be replaced?
Should the end customer of the appliance have access to change the fuse?
Should the fuse only be accessible from outside the appliance?
How much is available to spend on safety and reliability?

2P 175A 600V PDB DIN RAIL MOUNT Description POWR-BLOK power distribution blocks offer a safe, convenient way of splicing cables, providing a fixed junction tap-off point or splitting primary power into secondary circuits. Lx2xxx-DIN series offers integral DIN-rail mount and an optional hinged safety cover. These blocks can be utilized wherever power needs to be distributed to more than one load. Optional power distribution block covers provide protection against accidental shorting between poles caused by loose wires, tools, or other conductive material. They also protect personnel from accidentally contacting energized connectors. Connectors Box lug connectors are designed for use with a single or multiple, solid or class B or C stranded conductor. For UL approved use of more than one conductor per connector opening, contact Littelfuse Technical Service at 1-800-TEC-FUSE or techline@littelfuse.com. Ampere Ratings The ampere rating per pole for power distribution blocks is based on the line ampacity of 75 °C insulated conductors per NEC Table 310.16. If 60 °C insulated conductors are used, load must not exceed the ampacity of 60 °C conductors. Use of conductors rated in excess of 75 °C is permitted (for example 90 °C), however, load must not exceed the ampacity of 75 °C conductors. Applications • Heating, air conditioning and refrigeration systems • Elevator systems • Material handling equipment • Control panels, motor controls and switchgear ld-ls-datasheet
