Terminal block guarantes correct fuse insertion
Camden Electronics has launched a modified version of its CFTBN fused terminal block featuring double polarisation of the fuse carrier to ensure correct insertion of fuses.
The new CFTBN is the first fused terminal block in the world to have both UL and CSA approval (cUR us).
Many applications where fused terminal blocks are used also feature a small clear polythene bag attached to the panel or enclosure containing spare fuses for the various circuits within.
Engineers and technicians will be familiar with searching through a selection of fuses to find the correct replacement.

Fused terminal blocks with UL approval

Sealed lead-acid batteries are UL approved
Camden Electronics has introduced its upgraded and enhanced Eleckson range of sealed lead acid batteries, the UL-approved Europa Plus family.
With Camden's new CFTBN fused terminal block, such inconveniences are a thing of the past.
The correct spare fuse is safely stored at the point where it is required, becoming available when the fuse carrier is removed from the terminal block.
The new CFTBN also features redesigned square screw turrets with thicker walls that strengthen the overall construction of the terminal blocks.
Compared with previous generation products, the CFTBN terminal blocks offer exceptional strength.
Camden has also enhanced the design of the fuse carrier so that finger grip is improved.
This makes insertion and removal of fuses easier than with previous generation components.
The fuse carrier is also polarised to ensure that fuses are inserted properly and to protect fuse contacts within the terminal blocks from damage.
The carrier also provides positive feedback that the fuse has been inserted fully.
CFTBN fused terminal blocks are available with a one- to five-pole terminal strip plus 5 x 20mm fuseholder to IEC257.
Meeting IEC creepage and clearance requirements (8mm), the CFTBN's specifications include IP20 finger protection, 4mm2 cable entry and 10mm fixing pitch.
Screw/dust protection covers are also available as an option.
Camden Electronics' original CFTBN fused terminal block module was the first of its kind to get full UL approval opening up new markets for the component.
The connector simplifies manufacturing of products such as security equipment, emergency lighting, power supplies, luminaires and fluorescent fittings with the terminal strip featuring an integrated fuse holder.
In addition, customising the connector is a simple task enabling users to produce multipole fused units thanks to the terminal block's unique interlocking system.
The addition of a spare fuse option makes the new CFTBN terminal block an even more convenient product and provides users with additional flexibility.
The standard terminal options of single to five-pole terminal strips are rated at 440V and the fuse module is uniquely able to take glass- or ceramic-bodied types.
Individual fuse modules can easily be interlocked onto the standard fused part of the block allowing construction of any number of additional fused lines, as required.
Standard versions cover one to five poles with earth screw and without wire protectors.
Additional versions encompass blocks with or without earth and with or without wire protectors on all poles.
Perfect for protecting lighting equipment, power supplies, fire and security systems and domestic control applications, the new design has IMQ, VDE, SEMKO, FIMKO and DEMKO approvals pending.
