PFISTERER ISICOMPACT

Tap Connector 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 to modern labour standards and is perfect for live-line working.

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.

The patented design offers the following advantages compared to conventional clamping rings:

• Single-screw solution with built-in torque wrench
• IP2X contact protection against electrical hazards during all assembly steps
• Stripping of tap conductors no longer necessary
• Tap conductors are inserted, laborious threading from the front no longer required
• Flexible pressure plates ensure a continuous contact force
• Reduced variant diversity due to broad application areas
• Compact designs
• Suitable for all cable conductor types (EN 60228 -N(A)YY, N(A)2XY, N(A)KBA, N(A)Y2Y, N(A)2X2Y)

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.

How The ISICOMPACT Works?

Single-screw system

• 4-conductor branch by tightening one screw
• Screw connection can be placed in any position
• Quick and simple installation

Piercing contact technique

• No stripping of the conductors
• Shock-proof protection against live conductors
• Fast installation – good occupational safety

Cross-wedges

• Penetrate through insulation
• Support of the main conductors
• Reliable branch connection over the full service life

Functional product design

• Touch-safe at every installation step
• Stepless adjustment to conductor cross-sections
• Branch conductors are simply placed into the clamp
• Good occupational safety – simple installation

Universal application

• Large cross-section ranges
• For all types of conductor
• For aluminium and copper conductors
• Fewer different variants and low inventory costs

Shear-off nut

• Defined shear-off torque
• Optimal contact forces
• Screw breakaway signals end of completion of the installation
• Simple installation

Spring elements

• Constant contact quality
• Compensation of mechanical settling losses
• Reliable contacting over the full service life

Protection ribs

• Prevent premature penetration of contacts into main line
• Breaks during tightening of clamp
• Break if clamp is distorted
• Shock-proof protection throughout all installation steps for live line work

Insulating wall with inspection openings

• Protection against touching the branch line
• Enables checking of conductor position
• Good occupational safety for live line work

Installation using standard tools

• Insulated tools in accordance with EN 60900
• Requires 13 mm or 17 mm wrench
• No torque wrench
• Simple installation

How Has The ISICOMPACT Improved?

Steel plates with spring characteristics ensure contact force over life time.

• Steel spring plate for the movement of cable, to ensure a flexible contact system at all times
• Indicates the installer that the clamp has reached the right contact force

Support brackets prevent piercing the insulation before tightening the screw

• Tested by the German Liability Insurance Association (BG ETEM)
• During and after installation no live parts touchable
• VDE – Test-Finger, DIN VDE 0470 part 1
• Bath of steel balls, (as a more tough verification)

Shear-off nut

• 20Nm Shear off torque guarantees defined contact forces
• No torque wrench necessary
• 2 Functionalities

1. Defines the torque
2. Breaks the bolt
