Feature a enclosed, non-fused rotary disconnect switch designed for safe circuit isolation. Business impact: reduced arc flash exposure and safer maintenance workflows. Application: control panels in manufacturing lines and outdoor equipment enclosures benefit from reliable OFF isolation and clear visibility of the switch position. Feature b 600 V rating supports modern electrical distributions and higher voltage control circuits without compromising safety. Business impact: enables a single device to handle mid-range power switching, lowering part counts and simplifying wiring. Application: motor starters and power feeders in automation lines gain consistent performance and simpler spare parts planning. Feature c NEMA 4P enclosure with CE marking provides weather resistance and regulatory compliance. Business impact: expands deployment options to include outdoor and harsh indoor environments, reducing enclosure leakage and maintenance costs. Application: outdoor substations, wash-down areas, and exposed panels in process industries benefit from robust protection and certification confidence. Feature d 63 A current rating delivers dependable switching for moderate load profiles. Business impact: improves switching reliability, reduces nuisance trips, and supports predictable lifecycle costs. Application: feeder disconnects and machine control circuits in packaging, conveying, and fabrication lines. Feature e Compact footprint (12 in length, 12.25 in height, 7.5 in width) and 11.24 lb weight ease retrofit and new installs. Business impact: shorter installation time and easier enclosure planning, saving labor and downtime. Application: retrofits in existing electrical rooms or new panel designs align with common cabinet dimensions.

FAQs

Plan for the 12 in length, 12.25 in height, and 7.5 in width footprint to fit the enclosure opening. Ensure mounting locations align with standard panel cutouts and use appropriate hardware. Confirm non-fused selector operation and verify clear OFF positioning during installation to maximize safety and reliability.
The unit is rated for 63 A and 600 V, with a NEMA 4P enclosure and CE marking. These specifications support medium-load switching in demanding industrial environments and ensure compliant, safe operation in both indoor and outdoor panels.
Yes. The NEMA 4P enclosure provides weather resistance and protection against dust and water ingress, making it appropriate for outdoor or wash-down areas when used in compliant electrical installations alongside CE-marked components.
This switch carries the CE mark for European safety compliance and uses a rugged NEMA 4P-rated enclosure to meet environmental protection requirements. While other certifications may apply depending on project scope, these two provide robust baseline conformity for many industrial applications.
The non-fused selector and clear OFF state reduce energization risk, cutting maintenance downtime and potential arc-flash exposure. Its mid-range 63 A rating and durable enclosure simplify lifecycle planning, lower spare parts counts, and improve overall equipment reliability in automation and power-distribution applications.
