How to use

Mount the switching bar securely inside the distribution panel or enclosure following the enclosure manufacturer’s spacing and clearance guidelines. Connect incoming and outgoing conductors to the designated pole terminals, ensuring that conductor sizes and torque values comply with applicable electrical standards and the 160 A rating. Fit appropriate fuses for each pole and verify correct fuse type and rating before energizing. After installation, check connections and insulation, then restore power and test the switching operation under no-load and light-load conditions to confirm correct behaviour.

Recommendations

Use the Rittal 3‑pole load switching bar with fuses of the correct type and rating for the intended circuit, adhere to local electrical codes, and perform periodic inspections of connections and fuse condition to maintain safe operation.
