The Drummond G Clamp makes connecting to bus bars straight
forward. The clamp-on design eliminates the need to drill bus
bars and makes for a much safer reliable connection via a
standard 4 mm socket.
Ideal for connecting power monitoring and measuring equipment,
the new colour coded clamps make phase identification easy.
The insulated materials reduce the hazard to the operator and
the spring loaded contact pin and locking ring ensure reliable
results throughout extended logging periods.
The G Clamp can be tightened by hand when wearing PPE
gloves, eliminating the need to use tools in the bus bar chamber.
They are available in Brown, Black and Grey. The standard
fused version is supplied with a replaceable 0.5A fuse within the
clamping screw providing protection at the source. Other fuse
ratings are available on request.
Available individually and in 3 phase connection kit sets including
a blue unfused G clamp for the neutral connection which requires
25mm less clearance in front of the bus bar.
