The EZB630MLUG is a mechanical lug from the Easypact busbar accessory line, rated 0...630 A and designed for bare incoming cables with a cross-section range of 16 to 150 mm². It is a connection accessory — a cable lug — not a breaker or switch, so it sits between the incoming cable and the busbar system in a panel.
The 630 A rating is the maximum continuous current the lug is designed to carry — sized for a main feeder or a large branch circuit in a distribution panel. The 16–150 mm² cable range tells you the lug body and clamping geometry accept that cross-section; if your incoming cable is outside that range, this lug won't grip it properly. Because it is a mechanical lug (not a compression or crimp type), it uses a set-screw or clamp mechanism to hold the conductor — no special tooling needed, but torque to the manufacturer's spec matters for long-term connection integrity.
Deployment Context
This lug mounts onto the Easypact busbar system inside a panel — it is not a standalone terminal block. The busbar provides the mechanical support and electrical distribution; the lug is the interface point where the incoming cable lands. In a typical industrial panel, you would see these on the main busbar feeding a group of feeders or a large motor control center section.
