FAQs
To install the ER12-200J3PB in existing switchgear, verify there is adequate space for the enclosure, confirm alignment with bus connectors, and secure mounting per manufacturer torque specifications. Wire the device to the protected circuit using appropriate lugs, ensure the pistol-style handle operates freely, and test de-energization and re-energization sequences in a controlled, lockout-tagout compliant procedure. Maintain clear labeling for maintenance personnel.
The unit is rated for 200 A at 600 V with a NEMA 12 enclosure, designed to withstand dusty and damp environments. Safety features include a pistol-style handle for controlled isolation, CE marking for regulatory compliance, and fuse class J compatibility for coordinated protection. These specs support arc-flash mitigation, safer maintenance, and reliable disconnection in industrial settings.
ER12-200J3PB is well suited for manufacturing, processing, metal fabrication, and heavy equipment installations where robust enclosure protection and reliable circuit isolation are critical. It fits switchgear and motor control centers in environments with dust, moisture, or wash-down requirements, providing long-term durability and streamlined protection coordination with Eaton Bussmann series components.
The ER12-200J3PB carries CE marking, indicating compliance with relevant European safety and performance standards. Its NEMA 12 enclosure designation confirms suitability for indoor service in dusty or damp environments. These certifications support regulatory compliance, simplify cross-border procurement, and align with standard industrial protection practices in modern control panels.
Maintenance benefits include safer maintenance workflows, reduced arc-flash exposure, and fewer unplanned shutdowns due to reliable isolation.
