Applications & Use Cases

The 5SL3320-7YA provides C-characteristic protection suited for mixed loads with moderate inrush such as motors, transformers and control circuits. At 20 A and 4.5 kA breaking capacity, it is dimensioned for final subcircuit protection in commercial, residential and light-industrial distribution boards conforming to IEC 60947-2.

DIN-rail mounting and 3-module width allow high-density installation in standard consumer units and panelboards. Halogen-free construction and sealable toggle support fire-safety and lock-out requirements in institutional and infrastructure applications.
