FAQs
ER3R-30J3PR is designed for standard enclosure installations. Use a compatible panel with a suitable cutout size and mounting pattern, ensure the pistol-style handle is accessible for safe operation, and provide a compliant lockout/tagout point. Verify the enclosure is rated for NEMA 3R environments and use proper wiring gauge for 30A circuits.
Rated at 600 V and 30 A, it provides a robust disconnection function with a 3R enclosure rating, helping isolate power quickly while maintaining insulation and protection. The fuse-type J accessory option supports fast fuse protection and predictable interrupting behavior, and CE marking ensures compliance with international safety standards.
Yes, the NEMA 3R rating indicates suitability for indoor and outdoor installations where rain, dust, and corrosion resistance are needed. When used with a proper enclosure and sealing, it remains reliable under harsh industrial conditions, and its rugged pistol handle enhances operator safety during door-open and disconnect actions.
Fuse type J is a common Bussmann series fuse format used with the ER3R-30J3PR to provide overcurrent protection in a compact footprint. This compatibility supports predictable fuse replacement, maintains coordination with upstream protection devices, and helps minimize downtime during maintenance and service events.
The unit’s pistol-style handle and clearly marked disconnect point facilitate lockout/tagout procedures by providing a discrete, verifiable isolation point. When combined with a lockable hasp or tag, technicians can secure the switch during servicing, reducing accidental energization and improving safety compliance across maintenance programs.
