Eaton Specification Sheet - ER4P-16N6SR
Enclosed, rugged design provides NEMA 4P protection for washdown and outdoor environments. This enclosure ensures moisture and dust exclusion, reducing corrosion risk and the likelihood of nuisance trips. The ER4P-16N6SR is ideal for harsh industrial areas such as chemical processing, food and beverage, and outdoor switchgear, where reliable isolation is essential. Its robust construction supports long service life in demanding operation cycles and minimizes strategic downtime. Non-fused, selector operation simplifies the isolation sequence, delivering straightforward maintenance and safer lockout procedures. The design promotes rapid fault indication and minimizes handling errors during routine testing or start-up checks. For procurement teams, the clear 16A/600V ratings and standard Bussmann series compatibility support consistent performance across multiple control panels, reducing spare parts diversity and simplifying stocking. With a 16A current rating and 600V voltage rating, the ER4P-16N6SR handles common industrial control circuits without oversizing components. This leads to reduced enclosure footprint and lower total installed cost while maintaining compliance. The switch is well suited for motor starters, PLC inputs, and other isolated control circuits where quick, reliable disconnection is required, even in environments with limited maintenance access. Exact dimensions of 12 in depth, 12.25 in height, and 7.5 in width, paired with a weight of 11.24 lb, deliver a predictable footprint for retrofits and new installations alike. The enclosure's design supports straightforward mounting and wiring in standard electrical panels, and the 12 in depth aligns with common panel bus configurations. The compact form factor helps optimize space in crowded control rooms without compromising protection. Comprehensive documentation, including the data sheet and full catalog references, simplifies specification verification and procurement workflows. Access to official Eaton materials accelerates code compliance reviews, ensures you reference the correct catalog number ER4P-16N6SR, and enables technicians to verify installation procedures, torque values, and wiring schemes before work begins.

FAQs
For installation, align the switch within the panel cutout to maintain proper enclosure integrity, secure mounting hardware to the specified torque, and connect the input/output wiring per Eaton wiring diagrams. Use the non-fused selector to safely isolate circuits during commissioning, and verify CE markings and NEMA 4P sealing after wiring to prevent moisture ingress. Consult the official Eaton datasheet for torque values and recommended conductor sizes to ensure code-compliant installation.
Yes. The ER4P-16N6SR is rated for 600 V and 16 A, making it appropriate for common industrial control circuits, motor control applications, and process instrumentation. Its non-fused, selector configuration provides reliable isolation without introducing additional fuse elements, which can simplify maintenance and reduce start-up times in panel assemblies.
Yes. The device uses a NEMA 4P enclosure rating, which is designed for harsh or washdown-prone environments. This rating helps protect against dust and water ingress, enabling installation in exposed locations such as outdoor panels or facilities with rigorous cleaning regimes, while maintaining safe isolation procedures for maintenance and repair work.
Official Eaton documentation supports accurate specification and sourcing, including the ER4P-16N6SR catalog entry, the full Bussmann-series catalog PDFs, and a dedicated specification sheet. These resources provide wiring diagrams, dimensional data, torque values, and installation best practices to help procurement teams verify compliance and streamline ordering.
The non-fused design simplifies maintenance by eliminating fuse replacement, enabling faster isolation during testing and servicing. The selector operation provides clear operator indication and predictable behavior, reducing downtime and lockout complexities. Combined with CE compliance and a robust NEMA 4P enclosure, the ER4P-16N6SR offers safer, cost-effective isolation for routine panel maintenance and startup sequences.
