FAQs
To install the ER4-200N3PB, verify the panel footprint fits the 12.8 in depth, 18.6 in width, and 24.3 in height enclosure. Mount the unit using standard mounting brackets, connect the line and load conductors per the electrical diagram, and ensure the pistol handle operates freely without interference. Confirm CE compliance labeling and secure the enclosure to maintain NEMA 4 integrity during weather exposure.
The ER4-200N3PB is rated for 200A and 600V, accommodating high-current feeders and industrial circuits. The NEMA 4 enclosure provides weather and dust protection, and the non-fused design simplifies maintenance by allowing safe isolation without integral fusing. This combination supports reliable operation in demanding environments while meeting common control panel requirements.
Yes. The device uses a NEMA 4 rated enclosure, designed to resist rain, dust, and chemical exposure typical of outdoor or wash-down environments. CE marking adds regulatory assurance for European installations. When selecting for outdoor use, ensure proper clearance for the pistol handle and verify mounting and wiring clearance per installation guidelines.
Key certifications include CE marking and NEMA 4 enclosure protection. The 600V, 200A rating supports industrial power distribution needs, while the non-fused design aligns with specific electrical protection strategies. For regulated facilities, verify that the installation complies with local electrical codes and that labeling remains intact for ongoing compliance.
The enclosed rotary disconnect switch reduces downtime by enabling quick, safe isolation during maintenance and changeovers, while its rugged NEMA 4 housing minimizes weather-related failures. The pistol handle improves operator efficiency, and the non-fused design can lower component counts. Together, these factors translate to lower maintenance costs and faster panel commissioning in high-demand facilities.
