FAQs
When installing the ER4-200J3PR, ensure a suitable enclosure with enough clearance for a pistol-handled actuator and fuse-type J integration. Verify 600V system compatibility and assess mounting provisions within control panels or outdoor housings. Use appropriate torque on mounting hardware and follow lockout/tagout procedures to minimize startup hazards during commissioning.
The ER4-200J3PR provides a 200A amperage rating and 600V voltage rating, meaning it can safely interrupt and isolate mid-size power feeds. In design terms, plan for matching protective devices, ensure correct fuse selection (fuse type J), and account for insulation and clearance requirements per electrical codes when sizing feeders and downstream equipment.
Yes. The unit carries a NEMA 4 enclosure rating, offering protection against moisture, dust, and washdown environments. This makes it suitable for outdoor installations and damp production floors. For outdoor use, ensure proper environmental sealing, appropriate mounting, and periodic inspections to preserve enclosure integrity.
The ER4-200J3PR is CE marked, indicating European regulatory compliance for safety and performance. CE marking supports global procurement programs and supplier qualification. While other certifications are not listed, the NEMA 4 enclosure rating provides practical protection in harsh environments, aiding compliance with industry safety standards during system integration.
Maintenance benefits include safer, quicker isolation during servicing due to the pistol handle and robust enclosure. The 200A/600V rating reduces the need for multiple devices in mid-size circuits, potentially lowering inventory costs. CE and NEMA 4 compliance also minimize downtime related to regulatory scrutiny and environmental exposure in industrial facilities.
