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.
