ANSI 61 gray paint Mill-galvanized
Durable galvanized steel construction with ANSI 61 gray paint finish delivers long service life in demanding environments, reducing replacement costs and downtime while withstanding daily wear. The 100 A rating combined with a 22 kAIC interrupt capability translates to robust fault protection for metering panels and service entrances, helping utilities meet short-circuit requirements without oversizing equipment. A 4-jaw, 1-position jaw configuration supports flexible meter socket options and simplifies installation in space-limited enclosures, enabling quicker commissioning in B-Line series deployments. The surface mount method and 3R enclosure compatibility streamline installation in compact panels, reducing field labor and freeing up cabinet space for future expansions. Compliance with UL and EUSERC approvals minimizes regulatory risk and accelerates project approval, while the galvanised frame and test block availability support efficient commissioning and ongoing testing. This model also aligns with ring vs ringless metering approaches, providing installation versatility across metering schemes and reducing spare parts requirements for different sites.
