G Clamps for Busbar Connections

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, more reliable connection via a standard 4 mm socket. A 4mm shrouded socket is provided in the fluted head of the moulded screw. The connection is suitable for up to 10A continuous use at 600V AC, subject to appropriate rating of the 4mm plug and lead.

• Fused at point of contact
• No need for tools
• Spring loaded contact pin and locking ring
• 4mm socket termination
• Colour coded for phase identification
• Drummond clamps are available in kit format

The fluted grip features of the G Clamp enable the clamping screw and locking ring nut to be tightened by hand while wearing appropriate PPE gloves, eliminating the need to use tools in the bus bar chamber.

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 or for permanent monitoring.

The standard fused version of the Drummond Clamp is supplied with a replaceable 500mA fuse within the clamping screw providing protection at the source and is available in brown, black and grey.

Unfused versions of the Drummond Clamp are also available in brown, black, grey, blue, red and white. Subject to quantity, in line fuses, custom lead sets with customer specified length and termination are available. Alternative fuse ratings are also available.

Available individually and in 3 phase connection kit sets including a blue unfused G clamp for the neutral connection. The smaller barrel of the unfused design requires 25mm less clearance in front of the bus bar.
