FAQs
The ER3R-63N6SR is designed for use in industrial control panels and motor control centers requiring 600 V operation at up to 63 A. Its enclosed, non-fused selector configuration and NEMA 3R-rated housing make it suitable for both indoor and outdoor installations in harsh environments, helping panel builders meet space and safety requirements without compromising performance.
The non-fused selector design provides a straightforward ON-OFF control point without embedded fuses, reducing spare parts inventory and simplifying wiring during routine maintenance. This translates to faster switchouts, lower downtime, and improved safety when isolating equipment for service in automated lines and packaging machinery.
Yes. The ER3R-63N6SR carries a NEMA 3R rating, indicating suitability for outdoor and damp environments. This enclosure protection helps prevent moisture ingress and corrosion, enabling reliable operation in exposed installations such as outdoor panels, weather-protected enclosures, and factory exterior equipment.
This unit is CE Marked, signaling conformity with European safety and regulatory standards. For global projects, CE marking aids procurement and regulatory alignment, reducing the need for additional local certifications. The NEMA 3R rating further confirms suitability for external or damp environments in North American applications.
Choosing the ER3R-63N6SR provides safe, code-compliant circuit isolation with a compact footprint, reducing panel space and installation time. The 600 V, 63 A rating covers common motor and control circuits, while the CE Marking and NEMA 3R enclosure support global deployment and outdoor durability, contributing to lower total cost of ownership and faster project ROI.
