Three-phased short-circuiting device for bus bars-automatic extruded clamp CAE
Code: Msp – CAE – 3xSf/lf – Sp/Ip – P/p
The three-phased short-circuiting device is equipped with three automatic phase clamps (“CAE” type) which can be fixed on bus bars in indoor substations.
The “CAE” automatic clamp contains an extruded body made of alluminium alloy, a special trigger mechanism and a tightening screw with a bayonet terminal for coupling with PMU insulating sticks.
