FAQs
For panel installation, ensure matching footprint (12 in length, 12.25 in height, 7.5 in width) and appropriate mounting hardware. The non-fused, pistol-handle design simplifies operability, while the 600 V, 30 A rating supports typical industrial control voltages. Verify enclosure is exposed to compatible environmental conditions and that CE marking aligns with regional compliance requirements before commissioning.
Key specs include a 600 V voltage rating and a 30 A amperage rating, with a NEMA 4P enclosure for solid protection. The device is non-fused and uses a pistol-style handle for quick, safe operation. These attributes enable reliable isolation in motors, switchgear, and control panels while meeting CE compliance.
Yes. The NEMA 4P-rated enclosure provides protection against dust and water ingress in harsh environments, making it suitable for washdown areas, outdoor installations, and challenging factory floors. This enclosure supports long service life with minimal maintenance, reducing downtime caused by environmental exposure.
The ER4P-30N3PR is CE marked for European compliance and features a NEMA 4P enclosure rating, offering robust protection in demanding industrial settings. While UL or IP specifics are not listed in the provided data, CE marking and NEMA 4P protection are central compliance indicators for global deployments.
The non-fused design reduces spare parts and simplifies maintenance routines, contributing to lower ongoing costs. Its rugged enclosure and quick-action pistol handle shorten downtime during maintenance and re-energization, improving uptime and overall return on investment in continuous production environments.
