DiversiTech Fuse Acs 125V Box Cover LSRU

The DiversiTech LSRU is a 125 volt fuse for box cover unit applications, used in disconnect and control assemblies where a fused box cover provides both circuit interruption and overcurrent protection in a compact arrangement.

Box cover units integrate a switch and fuse holders into a device that mounts directly to a standard outlet or junction box cover, creating a fused disconnect without a separate enclosure. This arrangement is common where equipment requires a local fused disconnecting means and space or budget does not favour a full safety switch. The assembly is frequently found serving small motors, unit heaters, fan coils, and accessory equipment.

The 125 volt rating suits single phase 120 volt circuits, covering accessory loads, controls, small motors, and general equipment branches at that voltage. Applying a fuse rated below the circuit voltage is unsafe because the fuse may not reliably interrupt fault current, so verifying the voltage rating against the installation is essential.

Applications include small motor and fan circuits, unit heater controls, accessory and auxiliary equipment, control panel protection, and replacement in existing box cover disconnect assemblies during maintenance.

When replacing fuses in a box cover unit, confirm the fuse class, dimensions, amperage, and voltage rating match the original. Fuse classes are not interchangeable even when physical dimensions appear similar, because interrupting ratings and time-current characteristics differ significantly. Using an incorrect class can result in a fuse that fails to clear a fault safely or one that opens under normal load.

De-energize and lock out the circuit before opening the box cover unit or replacing fuses, and confirm the circuit is dead with a meter.
