Eaton ER4X-800L3PB Enclosed Rotary Disconnect - NEMA 4X
Part Number: ER4X-800L3PB
Quick Summary
Eaton Bussmann enclosed rotary disconnect switches provide reliable isolation for electrical power feeds in industrial control panels. In harsh environments downtime and maintenance costs rise when enclosures fail to protect against dust, moisture, and accidental contact. This ER4X-800L3PB model carries CE marking and a NEMA 4X enclosure rating, signaling robust protection and regulatory alignment for demanding installations. Combined with fuse type L and a pistol-style handle, it enables safe, quick operation, while the 600 V and 800 A ratings support high-current isolation. This combination delivers predictable compliance and reduces procurement complexity for engineers and procurement teams.

FAQs
Plan for panel mounting in standard electrical enclosures compatible with Bussmann series components. Ensure adequate clearance for the pistol handle operation and follow lockout/tagout procedures during maintenance. Verify CE compliance and NEMA 4X protection to maintain environmental integrity in dusty or wet environments. Use the fuse type L arrangement recommended by Eaton for coordinated protection.
The ER4X-800L3PB provides an 800 A amperage rating, a 600 V voltage rating, and a NEMA 4X enclosure rating. It incorporates fuse type L protection and a pistol-style handle for safe operation. The catalog number is ER4X-800L3PB, and the unit is CE marked for regulatory compliance in industrial installations.
Yes. The NEMA 4X enclosure rating ensures protection against dust, moisture, and corrosion in demanding environments. CE marking further indicates compliance with international safety and performance standards, making it a reliable choice for outdoor or wet indoor installations in industries such as water treatment, food and beverage, and packaging lines.
The device is CE marked and features a NEMA 4X rated enclosure. While the data does not list SIL or IP ratings, the CE mark and NEMA 4X protection address key regulatory and environmental requirements for industrial switchgear and protection products used in controlled settings.
The enclosed design reduces exposure to live components, facilitating safer maintenance and faster disconnect operations with the pistol handle. The 800 A rating supports scalable line capacity, while fuse type L aids selective protection. Together, these features reduce downtime, streamline spare-part inventory with compatible Bussmann fuses, and lower total cost of ownership over the equipment lifecycle.
