#CMT# #/CMT# The guard comprises a closure body (11) which covers the voltage-carrying parts (8) when in the closed position, the body being rotatable between open and closed positions about an axle mounted in the installation, and being biased towards the closed position by a counterweight. The guard also includes an actuator mechanism comprising a contact surface (16) which is secured to the closure body and adapted to convert linear movement of a pin (15) mounted on the drawer into rotary movement of the body. #CMT#USE : #/CMT# For voltage-carrying parts of an electrical installation with one or more pull-out drawers. #CMT#ADVANTAGE : #/CMT# A complex rod and/or tube mechanism is no longer required to operate the guard and a spring is not need to return the drawer to its closed position, making the design of the guard more simple, which makes it easier to install and less sensitive to failure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of the guard in the open position, with the drawer partly pulled out. 8 : Contacts 11 : Closure body 12 : Mounting frame 15 : Pin 16 : Contact surface. |
