What VOLTLOK replaces
Four separate parts out. One engineered solution in.
VOLTLOK simplifies the conventional arrangement by integrating the locking, earthing and conductor-clamping functions into one component.
Traditional arrangement
- — Separate drilled earth fixing
- — Crimped lug
- — Banjo or earth tag
- — Ring terminal
VOLTLOK
- — One precision-machined component
- — Two independent conductor entries
- — External clamping-screw access
Functional principle
How VOLTLOK works.
02 — Connect
One or two earth conductors are inserted into the independent conductor ports.
03 — Secure
Two A2 stainless steel screws secure each occupied conductor entry in accordance with the approved instructions.
04 — Inspect
Top-access screws support clear access for installation and inspection.
Functional overview only. Electrical equipment must be safely isolated, and installation must follow the approved VOLTLOK instructions and applicable wiring regulations.
Core engineering details
Purpose in every detail.
Dual-entry design
Two independent conductor ports support incoming and outgoing earth connections.
360° serrated interface
A full-circle serrated contact surface designed for consistent mechanical engagement.
Four A2 clamping screws
Two stainless steel screws are provided for each conductor entry.
