These overspeed governors are valid for activating instantaneous safety gears with rollers, instantaneous with shock absorber effect and progressives. There is the possibility of installation as overspeed governor (traditional overspeed governor) and/or for fulfillment of +A3 amendment of regulation N81:1/2:1998+A3:2009. As an overspeed governor for the installation of remote tripping at 24VDC (1A), 48 VDC(0,5A) and 230 VAC (0,15A).
For the traditional overspeed governor installed for +A3 the tripping mechanism will be 24 VDC (1,9A.), removing supply from the coil.
This overspeed governor can be installed on the left and the right of the guide rail without needing to be rotated and without any change in the design. Either direction of the pulley rotation can be used as direction of the activation in descent.
