DA530000 Mechanism

Mechanical drive

Type DA-53

For load break switch RV 53 with integrated earthing switch (3 positions switch on/off/earth).

Function
– switches on and off the load break switch
– opens and closes the integrated earthing switch

Operation
– frontal, manual operation using a handle
– optional motorisation for remote command

Functioning
– drive with 3 positions (on/off/earth) and 2 operating points
– mechanical drive with 2 springs
– both springs operate the same outgoing axis
– direct mechanical coupling of the axis on the switch
– the spring ‘line’ switches the load break switch (on/off)
– the spring ‘earth’ switches the integrated earthing switch (earth)
– using the manual handle the operator compresses the corresponding spring
– the spring expands upon passing a death point to operate the axis
– operating the handle in opposite sense allows for reverse switching

Properties
– guarantees switching independent from the operator’s agility
– 1 frontal position indicator, mechanically coupled onto the axis
– integrating all necessary interlocks to prevent erroneous operation
– includes interlock functionality for a door panel

Possible options factory mounted
– motor for switching the load break switch
– motor for switching the integrated earthing switch
– up to 3 auxiliary contacts on line
– up to 3 auxiliary contacts on earth

DA531001 Mechanism

Function
– switches on and off the load break switch
– opens and closes the integrated earthing switch

Operation
– frontal, manual operation using a handle
– motorized switching (on/off), local or remote (motor controls not included)

Functioning
– working principle identical to DA-53 mechanism
– drive with 3 positions (on/off/earth) and 2 operating points
– mechanical drive with 2 springs

– direct mechanical coupling of the axis on the switch
– the spring ‘line’ switches the load break switch (on/off)
– the spring ‘earth’ switches the integrated earthing switch (earth)
– the motor compresses the spring ‘line’ in both directions (on/off)
– an auxiliary switch on the operating point blocks the motor when manually operated
– the integrated earthing is switched using a manual handle, by compressing the spring ‘earth’

Properties
– guarantees switching independent from the operator’s agility
– manual operation using a lever remains possible
– 1 frontal position indicator, mechanically coupled onto the axis
– integrating all necessary interlocks to prevent erroneous operation
– includes interlock functionality for a door panel

Possible options factory mounted
– motor for switching the integrated earthing switch
– push or rotating buttons to operate the line (on/off)
– up to 3 auxiliary contacts on line
– up to 3 auxiliary contacts on earth
