FAQs

The ER12-800L3PR is designed for main isolation in control panels, motor starter enclosures, and power distribution segments within manufacturing and processing facilities. Its 600 V rating and 800 A current handling support high-demand line feeds, while the NEMA 12 enclosure protects against dust and splashes. This makes it a dependable choice for preventative maintenance, safety interlocks, and routine shutdowns in harsh environments.
Installers should verify panel space for the enclosure, routing of the pistol-style handle, and clear access for safe operation during disconnect. The device is suited for standard panel cutouts used in industrial electrical protection applications and should be wired per applicable electrical codes. Ensure proper venting and torque settings for the fuse class L contact assembly to maintain reliable operation and extend service life.
Key ratings include a 600 V voltage rating, 800 A amperage rating, and a NEMA 12 enclosure. The unit uses fuse class L and features a pistol-style handle for safe, controlled operation. CE marking confirms European safety compliance, making it suitable for mixed regional installations where regulatory alignment is essential.
By providing a clearly marked, high-reliability isolation point, the ER12-800L3PR minimizes the risk of accidental energization during maintenance. The pistol handle offers ergonomic operation, while the fuse-class L compatibility ensures quick and safe disconnection of circuits. This combination reduces maintenance time, enhances operator safety, and lowers the likelihood of unplanned downtime.
