Virtually unbreakable terminals
Kwikblok® rail-mounted terminals and accessories from Pratley are not only smaller and more compact than ordinary terminals, but virtually unbreakable due to them being manufactured from Polyamide 6.6, which is exceedingly tough.
They have an extremely short assembly time due to the modular and interlocking nature of the products. Kwikbloks® can be mounted on a standard N35 rail by simply pushing the pre-assembled blocks onto the rail, or by snapping a group of pre-assembled blocks onto the rail.
Once snapped-on, the feet of the terminals are relieved from stress, which means that the plastic will not fatigue. A single-piece housing prevents side thrust on the plastic, which eliminates cracking completely, according to Pratley Marketing Director Eldon Kruger.
The terminals also incorporate unique ‘griplok’ contacts that provide security against any screws coming loose, while the ‘griplok’ shoe makes for easy wire insertion and protection. The spring-loaded ‘griplok’ shoes ensure secure contact even with cold flow wires, while the roll threaded screws allow for very high clamping torque.
“We have a wide range of accessories in the range including VL connecting straps, VBU supports, VBL removable jumpers, VSK safety covers, VS connecting clamps, IW and iWFK2.5 insulating partitions, SK end clamps, KAW safety covers, VB and SB2.5 connecting links, STB plug sockets, PST test plugs, mounting rails, and G-cartridge fuses,” Eldon adds.
In addition, separator blocks can be supplied with a TS plug for easy disconnecting (IKTS4). These serve to open and/or close the circuit easily without removing the conductor. The IKTS4 separator blocks can also be fitted with a variety of useful electronic plug accessories. The IKT10 universal separator can accept test plugs/sockets or removable jumper connection terminals. An HSK50 general strip marker is also available to fit all Kwikblok® sizes.
Other technical features of the Kwikblok® range include:
- Temperature resistance of 100°C (continuous) and 170°C for short periods
- Melting temperature of 240°C, a dielectric strength of 50 kV/mm
- Comparative tracking index in excess of 400
- Made from self-extinguishing material
- Resistance to petrol, oils, grease, and alcohols
- Available in Ex e versions for hazardous locations
“We are also able to factory fit Kwikblok® terminals in Pratley junction boxes to our customers’ exact specifications. This saves the contractor a lot of installation time and labour out on-site,” concludes Eldon.
