1 Spring Terminal Technology
Introduction to CAGE CLAMP® and Mersen’s spring terminal technology

2 Spring Terminal Technology
Mersen Spring Terminals versus Screw Terminals Wire retention spring reinforces high contact pressure Wire surrounded on all four sides “S” bend provides defined contact area

3 Spring Terminal Technology
The Spring Terminal Advantage Higher Degree of Reliability Low contact resistance Vibration, corrosion and temperature cycling resistant Lower Total System Cost Material and labor Increased Ease-of-Use Tool-free, simple to operate CAGE CLAMP has over 25 years of field experience and acceptance!

4 Spring Terminal Technology
Higher Reliability – Contact Resistance Every electrical connection resists the flow of electrons As the flow is impeded, voltage is lost, heat is generated Contact resistance of screw terminals can vary as vibration, corrosion and temperature cycling impact the contact point Spring terminal technology has very low contact resistance which is maintained over time even in hostile environments Micro-scale image of two contact surfaces

5 Spring Terminal Technology
Higher Reliability – Performance Under Vibration Tested under vibration to 2000 Hz, acceleration up to 80G Tested for resonant frequencies from 5Hz to 250Hz Tested to shocks of 109G in the X, Y and Z-axis No contact failure, no wire damage, maintenance free

6 Spring Terminal Technology
Higher Reliability – Performance Under Corrosion Spring terminal material is made of corrosion resistant material (stainless steel) Tin-plated current carrying bar ensures gas-tight connection

7 Spring Terminal Technology
Higher Reliability – Performance Under Temperature Cycling As temperatures fluctuate metals expand and contract Different metals expand and contract at different rates and conductors deform Screw terminals are static, expansion and contraction will have a negative impact on contact pressure Spring terminals are dynamic and will compensate for changes

8 Spring Terminal Technology
Lower Total Cost – Material and Labor Reduce installation time by up to 75% by installing conductors without the need for tools or torque specifications Flip open and close the terminal lever in just seconds Maintenance free, spring terminals eliminate the need for routine screw terminal re-tightening

9 Spring Terminal Technology
Increased Ease-of-Use No tools required – Wire can be inserted and terminated into the fuseholder without the use of a screwdriver or other tools Simple to operate – No torque specs to follow, just open and close terminal via the lever Superior connection every time, independent of operator skill Terminal Closed Terminal Open

10 Spring Terminal Technology
Features and Benefits – Summary Higher Reliability Low contact resistance Superior performance under vibration Corrosion resistant Superior performance under temperature cycling Lower Total Cost Reduce installation time by up to 75% Maintenance Free Increased Ease-of-Use No tool required Superior connection independent of operator skill

11 Spring Terminal Technology
Product Offering USG series fuseholder now available for class CC (USGCC), midget class (USGM) and photovoltaic midget class (USGM-HEL) Mersen is the first manufacturer to offer screw-less, spring pressure, wire termination technology into a power fuseholder, delivering the best of both technologies to its customers
