FAQs
ER12-40N3PR is designed for standard industrial control panels with NEMA 12 protection. It supports common panel mounting practices and wiring practices found in many machine tools, conveyors, and packaging lines. The pistol-handle, non-fused design simplifies lockout/tagout and allows straightforward integration into existing enclosures without requiring special adapters. For retrofit projects, verify enclosure clearance, door access, and wiring space to ensure a trouble-free installation.
This unit is rated for 600 V and 40 A, with a non-fused design and NEMA 12 enclosure. It provides safe isolation without a fuse, enabling quick maintenance lockout. CE marking confirms conformity with applicable EU directives. The enclosure helps protect against dust and water exposure in typical industrial environments, supporting reliable operation under normal to demanding load conditions.
Industries such as manufacturing automation, packaging lines, and machine tool operations benefit from the reliable, non-fused isolation this switch provides. It is well-suited for control panels in harsh environments where dust and splash resistance (NEMA 12) and safe, fast lockout are critical. The pistol-handle design also supports quick, safe operation during routine maintenance and emergencies.
Key certifications include CE marking for European compliance and a NEMA 12 enclosure rating for environmental protection in industrial settings. The 600 V/40 A electrical rating meets common industrial load demands, while the non-fused configuration supports simpler maintenance and faster service restoration. Always ensure installation aligns with local electrical codes and panel-specific safety requirements.
The non-fused design reduces spare parts needs and fuse replacement cycles, lowering maintenance costs. Pistol-handle operation speeds lockout/tagout and service, cutting downtime during routine maintenance and fault isolation. Rugged construction and CE/NEMA-compliant features provide predictable performance, enhancing safety, compliance, and overall uptime for automated production lines.
