SNAP ACTION SWITCHES type SAS-00, SAS-03

Transcription

1 EN SNAP ACTION SWITCHES type SAS-00, SAS-03 SAS 00 and 03 Series snap-action switches have one NO and one NC contacts. The change of the switching position is realized by the mechanism, which ensures rapid switching and gives the possibility for switching of high currents. The electric circuit interrupts by double break. The snap-action switches are in the procession of a mechanism, which in case of short-circuit breaks forced the welded normally closed contact. The contact system is placed in a small design made of transparent light blue plastic material with high electrical and mechanical characteristics. The contact system in various versions is actuated directly or through lever system.

5 SAS 03a 8 0, max x 4.3 x 67 ЕLECTRICAL CONNECTION * SCREW-TYPE TERMINALS - Connected to the snap action switches wires can be single and multiple 0,75 mm to,5 mm (AWG 8...4). At mounting of ferrules the maximum wire gauge is.5mm² (AWG 6). - Two conductors max can be clamped per terminal with the same wire gauge. - Wire insulation must be flush with the clamping unit. - Tightening torque of terminal screws should be within 0,5 Nm... 0,9 Nm. * FLAT QUICK-CONNECT TERMINALS (for SAS 03) - Use flat tabs 6,3 mm x 0,8 mm (DIN 4647), preferably with insulated cable sleeves. - If necessary, the terminals are provided with a forming point where the flat tab can be angled by < 90. MECHANICAL FASTENING * FRONT MOUNTING - At SAS 00 b by way of the nut retainers (M3), inserted in the housing of the snap action switch. Tightening torque must be max. 0,9 Nm. - At switches with roller levers (SAS 00 a, SAS 00 c и SAS 00 d) - by way of the mounting brackets. * GANGING (lateral mounting) for SAS 00 e and SAS 00 b - Without rivets - through the two transversal bore holes with 4 mm screws or bolts. - With rivets - through the two transversal bore holes with 3 mm screws or bolts. - Between the bolts head and snap action switches place feder washer. - In order to safeguard clearance and creepage distances it is necessary to use insulating plates when ganging or mounting switches on uninsulated surface. ATTENTION:. At mechanical mounting make sure to have fixing points!. The values for maximum tightening torque must not be exceeded. 3. Be sure that after mounting, the wires are free of mechanical tension! 4. When using of screw-retaining varnish, cleaning agents, adhesives etc., they must be compatible with polycarbonate. 5
