FAQs
ER1-40N3PB is designed for straightforward panel integration with a compact footprint and pistol-handle operation. When installing, ensure proper mounting within a NEMA 1 enclosure, correct alignment of the actuator with the panel opening, and secure electrical terminations for 600 V circuits rated at 40 A. Follow lockout/tagout procedures and verify CE compliance documentation for regional requirements to minimize startup risk.
The non-fused design simplifies servicing by removing the need to replace fuses during routine isolation tasks, reducing downtime. For lockout/tagout, the pistol-style handle provides a clear, ergonomic grip enabling quick de-energization and safer operational sequencing. This configuration lowers arc-flash exposure during maintenance while maintaining reliable electrical isolation for the protected circuit.
Yes, ER1-40N3PB is rated for 600 V and 40 A, making it suitable for general-purpose control circuits in light to medium-duty industrial applications. The NEMA 1 enclosure provides basic indoor protection, while the CE marking confirms conformity with applicable European standards. For higher-energy applications, verify the control circuit design and consider additional protective devices as required by your code and safety programs.
ER1-40N3PB carries CE marking and a NEMA 1 enclosure rating, which denote compliance with European safety standards and basic indoor protection, respectively. These certifications are important for OEMs and integrators planning compliant installations in commercial and light industrial environments. When sourcing, also reference the Eaton specification sheet to confirm compatibility with your panel design and regional compliance requirements.
The ER1-40N3PB delivers ROI through safer, faster maintenance workflows and reduced downtime thanks to its non-fused design and ergonomic pistol handle for quick isolation.
