FAQs
ER4-800N3PB is designed to integrate with Eaton Bussmann series panel architectures. It provides a standard enclosure rating and a non-fused disconnect with a pistol handle, facilitating straightforward mounting, wiring, and safe isolation in control cabinets and MCCs. Verify catalog number ER4-800N3PB and CE compliance during procurement to ensure correct fit and compliance with local codes.
This model delivers 600 V voltage rating and 800 A current rating, with a NEMA 4 enclosure. It is non-fused, enabling external fusing as needed, and includes a pistol-style operating handle for safer, more ergonomic manual operation. The CE marking confirms conformity with European electrical safety standards, suitable for a range of industrial applications.
Yes. The unit is designed with a NEMA 4 enclosure, which provides protection against weather, splashing water, and dust. This makes it appropriate for outdoor installations or damp environments within industrial facilities, ensuring reliable isolation even under challenging conditions.
The ER4-800N3PB carries CE marking as part of its compliance profile, indicating conformity with applicable EU safety standards. It is also rated for NEMA 4 enclosure protection, aligning with industrial reliability requirements and enabling safer operation in harsh environments.
With a non-fused design and robust enclosure, maintenance focuses on mechanical operation and enclosure integrity rather than fuse management. The 600 V/800 A rating supports long service life under high-load conditions, reducing downtime during routine maintenance and improving overall equipment availability in manufacturing lines.
