Arc Flash Safety System
Often triggered when a worker opens a door to access controls, an arc flash explosion can occur when an electrical fault occurs within the confined space of an enclosure — and can cause devastating personal injury and extensive equipment damage. The Arc Flash Safety System isolates workers from energized equipment within the encloure. The Intersafe data-interface ports —programming ports designed to provide data access without opening enclosure doors — are at the heart of the system. Completing the system are steel and stainless steel window kits for exterior visual monitoring of controls, folding shelves to hold laptops and test equipment, and external keyboard and document storage. The mild steel, or stainless steel and polycarbonate, enclosures feature connectors that interface with all major data and industrial communication protocols, and either a breaker-protected ground-fault circuit interrupter (GFCI) or standard duplex outlet.

CC3000 operator-interface enclosure system
Built on a modular platform to offer maximum flexibility, the CC3000 operator-interface enclosure system protects operator interface terminals and electronic monitors in UL Type 12 industrial environments. The enclosures feature single-wall aluminum construction to dissipate heat efficiently and eliminate heat buildup inside the enclosure. In many cases, this eliminates the need for active cooling, but if needed, an internal fan can be installed. Four standard models are sized to fit the most popular HMI tools, including flat-screen devices, lights, meters and gages; units can also be custom-sized to the user’s exact requirements in millimeter increments from 250 ¥ 250 mm to 600 ¥ 600 mm. The CC3000 meets UL 508A, UL 508, UL Type 12, NEMA/EEMAC Type 12, and CSA C22.2 No. 94 Type 12 standards.
