FAQs
The ER3R-25N6SR is designed to integrate with typical industrial control panels and Bussmann series protection components. It uses a standard enclosure interface and a non-fused selector, facilitating straightforward mounting in existing cabinets or on panel doors. This compatibility supports rapid deployment, minimizes modification work, and helps maintain enclosure integrity while delivering reliable isolation for motors, feeders, and PLC-driven equipment.
Key performance specs include a 25 A amperage rating, 600 V voltage rating, NEMA 3R enclosure, and CE marking. It is a non-fused selector switch optimized for safe, repeatable disconnections in industrial environments. These specifications ensure compliant isolation for control circuits and reliable operation in typical factory and outdoor applications, reducing risk during maintenance and service work.
Yes. The ER3R-25N6SR features a NEMA 3R enclosure, which is specifically designed for outdoor or damp locations and harsher environments. Combined with CE marking and a robust 600 V/25 A rating, it provides dependable isolation in weather-exposed panels, outdoor machinery, and process installations where protection against moisture and dust is essential.
Because it is non-fused and selector-based, maintenance focuses on ensuring the mechanical integrity and clear visibility of the operating position. Regular visual checks, proper labeling, and verification of the isolation path during service windows are recommended. The absence of fuses reduces spare parts complexity, while the CE and NEMA 3R ratings support ongoing reliability in industrial use.
The ER3R-25N6SR enhances safety by providing a clearly isolated, easily operable disconnect for maintenance and commissioning, reducing arc exposure and accidental energization. It also lowers downtime during circuit testing and service, improves regulatory compliance with CE marking and NEMA 3R protection, and simplifies stocking by aligning with Bussmann series components, contributing to faster project delivery and long-term cost savings.
