Each terminal assembly consists of a tin-plated, copper/zinc, split, current bar, whichfarms a knite blade contact. Thls is fitted wlth a zinc-plated steel, sliding yoke and screw at each end.When the screw Is tlghtened, the yake is compressed against the current bar and serrations incorporatedin Öle surface prevent slippage of the conductor.The disconnection link conslsts of a polyamide PA66 insulated, hinged tever, which ls fitted with a tinplated,copperltln, leaf spring contact. The disconnection link is operated by an upward movement of thehlnged contact lever; this breaks the connection between the two, !mife contacts.A polyamide PA66 Insulated cover is fitted in the moulding to hold and shield the main knife terminals.Self·deformation is ineorporated in the design when the serews are tightened down, this is used toprovide an automatie and progressive anti·rotation/anti·vibration locking effect.On both the 32 mm (SAK R) & 15 mm (SAK R 15) rail versions, a f1at section, stainless steel spring isIocated in a recess at the foot of the terminal housing, which allows it to be dipped onto a TS32 or TS15assembty rail respectivefy. A natural spring effect is deslgned into the plastic moulding of Öle 35 mm(SAK R 35) rail version to alJow it to be dipped onto a TS35 assembly rail.The following terminals are covered:Terminal Type Voltage Current Minimum Maximum Terminal reslstancerating rating cable slze cable size (mn @ 20·C)(V) rÄl (mm') (mm') (see note below)SAK R (oolvamlde PA66 400 10 0.5 4 2.66SAK R (melamlne 400 10 0.5 4 2.3BNote: When any cf the above tenninals are fitted inside jundion boxes, the terminal resistance figure to beu.sed for the purpose of assessing the maximum power dissipation is as listed in table above.The voltage rating Is an absolute condition of use as stated In Table 7 of EN 50021: 1999. The eurrentrating Is not an absolute flQure but is the recommended value when used in a general purpose junctionbox or marshalling box with cables having the following ratings:Cable Size mm 0.5 1 1.5 2.5 4Maximum Current A 5 10 10 10 10Higher currents may be permitted subject to individual examlnation of each specific application.Date 1 October 2004latest 25 November 2005issueThis certificate and Its sdledules may only be reproduced in its entirety and wlthout any changePage 2 of 4 Sira Certiflcatlon ServiceForm92191ssue 3Rake lane.ECCIestOll, Chester, CH4 9JN, EnglandTel:.44 (0)1244 670900 Fax: +44 (0)12 .•.•• 681330Email' exhazardOsira ccwkSefVice IS a service 01 $ira Test & Certihcaüon UdSira Cenifiealioo
