FAQs
ER1-16N3PR is designed as an enclosed rotary disconnect with a pistol handle and non-fused operation. It is compatible with general indoor panel assemblies and is intended for straightforward wiring in standard control circuits. Its compact enclosure supports retrofit and new builds, while the 'Used with all switches' note ensures broad interoperability within Eaton Bussmann series installations.
The model operates at 600 V and is rated for 16 A, with an indoor, general-purpose NEMA 1 enclosure. These ratings support common industrial control circuits and panel isolation needs, offering reliable performance in typical manufacturing and processing environments without fused protection.
Yes. With a 600 V rating and 16 A current capacity, this enclosed rotary disconnect is suitable for indoor, general-purpose control applications in industrial panels. The NEMA 1 enclosure provides basic protection against dust and incidental debris in standard environments.
The provided data lists a NEMA 1 enclosure and key electrical ratings but does not specify CE, IP, or SIL certifications. For confirmation on those certifications, consult the Eaton specification sheet (ER1-16N3PR) or contact Eaton technical support to verify regulatory compliance for your region and application.
Non-fused designs reduce replacement costs and arc-flash exposure during maintenance, enabling safer lockout/tagout procedures and faster turnaround. The pistol handle adds ergonomic efficiency, while the compact enclosure aids in space savings and easier retrofits. Over time, these factors can translate to lower downtime costs and improved maintenance reliability in panel-heavy environments.
