Description
175A 600V 3P PDB
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
