ISICOMPACT from PFISTERER
Branch Terminals for LV Cables & House Service Connections
Practical installation, good occupational safety and high levels of operational reliability are fundamental criteria for home power connections. ISICOMPACT by PFISTERER – the inventor of multi-conductor cable branch technology is the perfect solution.
With the invention of the compact screw terminal in 1968, PFISTERER set the standard in house connection technology. Well over 20 million SCK have been installed since then. Fast forward 30 years and the time had come for further development – ISICOMPACT technology.
The ISICOMPACT establishes all contacts for a 4-conductor cable branch using a single screw connection. When the screw connection is tightened, contact is established by piercing the insulation on the main line and branch lines.
Once the required clamping force has been achieved, the screw shears off and thereby ensures successful installation. By providing protection against contact and thus against electrical hazards, the ISICOMPACT is designed for live line work.
It is currently the only cable tap connector that also meets the strict requirements of BSI 862 – a German approval that enables a process for live line work without additional PPE and requires LLW electricians to undergo special training and the LV power network provider to be approved.
Six screws become ONE
ISICOMPACT reliably creates a branch connection from the supply cable to the end customer with just one screw. This simplifies and speeds up installation.
Where as conventional “clamping rings” have at least six screws, one or more of which are usually poorly accessible, the single screw on the ISICOMPACT can be placed on the cable to suit conditions, and conveniently tightened from above or from the side.
Simple & safe installation
Tightening the screw establishes all conductor contacts reliably and safely to form the cable branch. Insulation does not have to be removed from the conductor; contacts are established by piercing the insulation.
Spring pressure plates on both sides of the clamp ensure permanent contact force. The design and installation sequence ensure protection against contact with live parts throughout all work steps.
Live line working
Providing shock-proof protection against electrical hazards, ISICOMPACT is designed for live line working. The “green” version ISICOMPACT plus is the only cable tap connector approved by employer’s liability insurance association BG ETEM for live line work without additional PPE. It meets the strict requirements of DGUV Information 203-031 (formerly BGI 862).
ISICOMPACT – Reliable home connection with just one screw
High flexibility
Compared to conventional cable tap connectors, ISICOMPACT offers significantly larger clamping ranges and high flexibility in use. Altogether there are two standard sizes and seven variants. ISICOMPACT multi combines the S, M and 3 1/2 variants in one product.
As a result, electricians are equipped for all eventualities. At the same time, the smaller number of variants reduces the risk of using the wrong type and cuts inventory costs.
Unique shear-off technology
ISICOMPACT features a specially developed shear nut which performs two tasks during fitting. It defines the installation end-point and minimises the clamp’s dimensions. Once the optimal contact force is reached, the shear nut operates and the protruding section of the screw breaks away burr-free. Subsequently, ISICOMPACT fits into all commercially available cast resin joints.
Currently used by all major energy suppliers. ISICOMPACT cable branch technology
Everything from a single source
Clamping ring and cast resin joints from the inventor of multi-conductor cable branch technology. As a contact technology specialist and solution-oriented system provider, PFISTERER offers a wide selection of cast resin joints to complement the ISICOMPACT connection system, as well as complete matching sets comprising a cast resin joint and the cable tap connector. Our proven two-component cast resins with excellent flow characteristics are available in tins or in a practical two-chamber bag.
