1 Spring Terminal Technology Introduction to CAGE CLAMP® and Mersen’s spring terminal technology
2 Spring Terminal Technology Mersen Spring Terminals versus Screw TerminalsWire retention spring reinforces high contact pressureWire surrounded on all four sides“S” bend provides defined contact area
3 Spring Terminal Technology The Spring Terminal AdvantageHigher Degree of ReliabilityLow contact resistanceVibration, corrosion and temperature cycling resistantLower Total System CostMaterial and laborIncreased Ease-of-UseTool-free, simple to operateCAGE CLAMP has over 25 years of field experience and acceptance!
4 Spring Terminal Technology Higher Reliability – Contact ResistanceEvery electrical connection resists the flow of electronsAs the flow is impeded, voltage is lost, heat is generatedContact resistance of screw terminals can vary as vibration, corrosion and temperature cycling impact the contact pointSpring terminal technology has very low contact resistance which is maintained over time even in hostile environmentsMicro-scale image of two contact surfaces
5 Spring Terminal Technology Higher Reliability – Performance Under VibrationTested under vibration to 2000 Hz, acceleration up to 80GTested for resonant frequencies from 5Hz to 250HzTested to shocks of 109G in the X, Y and Z-axisNo contact failure, no wire damage, maintenance free
6 Spring Terminal Technology Higher Reliability – Performance Under CorrosionSpring 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 CyclingAs temperatures fluctuate metals expand and contractDifferent metals expand and contract at different rates and conductors deformScrew terminals are static, expansion and contraction will have a negative impact on contact pressureSpring terminals are dynamic and will compensate for changes
8 Spring Terminal Technology Lower Total Cost – Material and LaborReduce installation time by up to 75% by installing conductors without the need for tools or torque specificationsFlip open and close the terminal lever in just secondsMaintenance free, spring terminals eliminate the need for routine screw terminal re-tightening
9 Spring Terminal Technology Increased Ease-of-UseNo tools required – Wire can be inserted and terminated into the fuseholder without the use of a screwdriver or other toolsSimple to operate – No torque specs to follow, just open and close terminal via the leverSuperior connection every time, independent of operator skillTerminal ClosedTerminal Open
10 Spring Terminal Technology Features and Benefits – SummaryHigherReliabilityLow contact resistanceSuperior performance under vibrationCorrosion resistantSuperior performance under temperature cyclingLowerTotal CostReduce installation time by up to 75%Maintenance FreeIncreasedEase-of-UseNo tool requiredSuperior connection independent of operator skill
11 Spring Terminal Technology Product OfferingUSG 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
