FAQs
Yes. The ER4-16N6SB is designed for enclosed installations in typical industrial control panels and service disconnects. It uses a non-fused selector for straightforward operation and aligns with Bussmann-series components. The unit provides reliable isolation within standard panel layouts, facilitating easy retrofit or new installations without extensive panel redesign.
The 600 V rating indicates the maximum operating voltage the switch is designed to safely interrupt. The 16 A rating specifies the maximum continuous current it can safely handle in its disconnect position. The NEMA 4 enclosure rating denotes weather and corrosion resistance suitable for indoor and some outdoor environments, ensuring dependable performance in harsh industrial settings.
This enclosed rotary disconnect switch is ideal for service disconnects and control panels in industrial environments. It supports motor control circuits, power distribution panels, and other applications where safe isolation, weather resistance, and regulatory compliance are required, especially in environments where quick, reliable one-position isolation is beneficial.
The ER4-16N6SB is CE marked, indicating compliance with European safety standards. It carries a NEMA 4 enclosure rating for weather resistance and is rated for 600 V and 16 A, signaling suitability for robust industrial installations. It is part of Eaton’s Bussmann series, aligning with common electrical protection and control system requirements.
Because the device is non-fused and uses a selector, maintenance tends to be simpler with fewer fuse-related parts to stock or replace. The durable NEMA 4 enclosure and standard ratings help minimize downtime during isolation tasks, contributing to improved uptime, reduced spare parts spend, and predictable maintenance planning for critical processes.
