Q1. What is a Pull Cap Fuse Holder?
A Pull Cap Fuse Holder is a type of modular fuse holder where the fuse carrier and cover plate — together forming the “cap” — pull cleanly away from the base to allow safe access to the fuse-link for inspection, testing, and replacement. The Lawson Type LPC PULLCAP is a 240/415V a.c. modular fuse holder that incorporates fuse-links to BS 88-1 and BS 1361, and is available in ratings of 5A, 20A, 32A, and 63A.
Q2. What is the difference between the fuse cap, carrier, and base in the Type LPC?
The Type LPC Pull Cap Fuse Holder is made up of three modular components. The base is fixed to the panel or DIN rail and provides the incoming and outgoing wiring terminals. The carrier holds the fuse-link and clips into the base. The cover plate (fuse cap) fits over the carrier, completing the assembly and providing insulation and protection. All three components are available separately, as well as in fully assembled LPCU units.
Q3. What current ratings are available for the Lawson Pull Cap Fuse Holder?
The Type LPC Pull Cap Fuse Holder is available in four current ratings: 5A, 20A, 32A, and 63A. Each rating has a corresponding colour-coded carrier and cover plate to help engineers and electricians quickly identify the correct fuse holder in a multi-way panel assembly without needing to read individual labels.
Q4. What voltage is the Type LPC Pull Cap Fuse Holder rated for?
The Lawson Type LPC is rated for 240V a.c. (single-phase) and 415V a.c. (three-phase) applications, making it suitable for both domestic consumer unit installations and commercial or industrial distribution panels.
Q5. What fuse-links are compatible with the LPC Pull Cap Fuse Holder?
The Type LPC Pull Cap Fuse Holder is designed to incorporate fuse-links conforming to BS 88-1 and BS 1361, including the Lawson Type L Consumer Unit Fuse-Link range. Always ensure the fuse-link current rating, voltage rating, and physical dimensions match the specific holder being used.
Q6. What wiring configurations are available for the Type LPC?
The 32A and 63A ratings of the Type LPC Pull Cap Fuse Holder are available in multiple wiring configurations to suit different panel layouts, including Double Front Connected (FC/FC), Front/Busbar Connected (FC/BBC), Front/Back Connected (FC/BC), Double Back Connected (BC/BC), and link variants (FC/FCL and FCL/FCL). This flexibility makes the Type LPC suitable for a wide range of incoming and outgoing cable arrangements.
Q7. Is a DIN-Rail Adaptor available for the Pull Cap Fuse Holder?
Yes. A DIN-Rail Adaptor is available for the 32A base (Reference: LPC 32 DA), enabling straightforward mounting of the Type LPC Pull Cap Fuse Holder onto standard DIN rails within control panels and distribution boards.
Q8. Can I buy the Type LPC as a fully assembled unit?
Yes. In addition to individual component parts (base, carrier, cover plate), the Type LPC is available as fully assembled LPCU units in ratings of 5A, 20A, 32A, and 63A — saving time on panel assembly and ensuring all components are correctly matched from the outset.
Q9. What colour coding is used for the Pull Cap Fuse Holder carriers?
The colour coding by current rating is as follows — 5A: White or Black; 20A: Blue or Green; 32A: Red or Black; 63A: Black. This colour coding applies to both the carrier and the cover plate, allowing fast visual identification of fuse ratings in busy multi-way panel assemblies.
