FAQs
The ER12-100CF2PR is ideal for main power isolation in control panels across manufacturing, packaging lines, and process equipment. Its NEMA 12 enclosure protects against dust and moisture, while the 600 V rating supports mid- to high-current machine loads. This makes it a dependable choice for industries demanding reliable electrical protection and straightforward maintenance.
This device provides a 100 A amperage rating and 600 V voltage rating, configured as a two-pole enclosure with fuse type CF and a pistol-style handle. It carries CE marking and a NEMA 12 enclosure, with overall dimensions of 11.8 in length, 10.8 in height, and 9.84 in width, and a weight of approximately 6 lb. These specs support robust protection and easy integration into standard panels.
CE marking confirms compliance with European safety standards, enabling easier cross-border procurement and conformity for international projects. NEMA 12 rating indicates protection against dust and light splashing in indoor environments, making installation suitable for factory floors and washed-down or dusty settings. Together, these factors simplify supplier qualification and site commissioning across global facilities.
Yes. The ER12-100CF2PR is designed as part of Eaton Bussmann series protection devices, featuring CF fuse type compatibility for coordinated overcurrent protection. When selecting accessories or replacements, ensure the fuse type and rating match the application load and wiring configurations to maintain UL/CE compliance and reliable operation.
Regular inspection of enclosure seals, fastener torque checks, and lubrication of mechanical linkage are recommended. Verify cleanliness to prevent dust ingress, confirm that the pistol handle operates smoothly, and test locking mechanisms during scheduled maintenance. Following a documented lockout/tagout procedure helps maintain safety and reduces unplanned downtime in high-availability lines.
