Distribution Blocks • Splicer Blocks • Covers
## **Specifications**
## **Description**
POWR-BLOKS[TM] 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.
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. To order protective covers, match the number of poles for the block to the cover.
## **Applications**
Typical applications include heating, air conditioning and refrigeration systems, el e va tor systems, material handling equipment, control panels, motor controls, switchgear, and anywhere power needs to be distributed to more than one load.
## **Connectors**
Box lug connectors are designed for use with a single, solid or class B or C stranded conductor. Use of more than one con ductor per connector opening or use of extra-flexible, fine-stranded conductors, such as welding cable, voids the UL Listing and may cause overheating. Manufacturers of cable ter minations can furnish crimp-on sleeves for fine stranded conductors which permit these conductors to be used with box lugs.
## **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.
**Voltage Rating** 600 V **Current Rating** Based on NEC Table 310.16, using 75°C copper wire **Material** Phenolic rated at 150°C and Thermoplastic rated at 125°C (LD1400 and LS1300 series only) **Connector** Standard: Highly con duc tive aluminum, tin plated Copper: Highly conductive copper, tin plated **Flammability Rating** UL94 V-0 **Approvals** UL Recognized - LD/LS Series (File: E171395) LFD/LFS Series (File: E309688) CSA Certified - LD/LS Series (File: LR700111) LFD/LFS Series (File: 007316_0_000) **Environmental** RoHS compliant, Lead (Pb) free **Ordering Information**

Updated at June 3, 2026
Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
