FAQs
The ER1-200J3PR should be mounted in a standard control cabinet or switchgear enclosure with adequate clearance for the pistol handle operation and wiring access. Ensure the enclosure provides NEMA 1 indoor protection, use proper conductor sizing for 200 A circuits, and follow relevant local electrical codes. Verify compatibility with Bussmann series fuse class J for optimal protection coordination.
Yes. The ER1-200J3PR is designed to work with fuse class J protection as part of Eaton Bussmann series, enabling selective coordination and straightforward fuse replacement. When planning a panel, ensure the fuse type and rating align with the controlled circuit load and the disconnect rating to maintain regulatory compliance and safe shutdown behavior.
This unit serves as a main or sectional isolation switch in control panels and machine controls where rapid circuit isolation is required. Its NEMA 1 enclosure provides indoor protection, while the 600 V / 200 A rating supports typical industrial loads. It’s particularly suitable for machine builders and panel shops integrating Bussmann series protection into existing Eaton systems.
The ER1-200J3PR carries CE Marked compliance and a NEMA 1 enclosure rating, indicating suitability for indoor electrical protection and equipment isolation in regulated environments. While not listing SIL or IP ratings, these marks help ensure compatibility with European and general industry standards for control panels and switchgear.
The pistol-handled, enclosed design enables quick, safe circuit isolation, which reduces maintenance time and downtime. Its compatibility with Bussmann series fuses simplifies spare-part inventories and procurement, contributing to predictable maintenance windows and improved asset availability, ultimately lowering total cost of ownership over the equipment’s lifecycle.
