Hazardous-rated metal 60-amp and 150-amp plugs and receptacles from Meltric Corporation are designed for Division 2/Zone 2 environments. The plugs and receptacles are cCSAus rated and listed to 75 hp. The amperage, voltage, horsepower and environmental ratings are indicated on the product labels. The receptacle has a dead front that isolates the supply contacts and prevents exposure to live parts. A safety shutter blocks access to the contacts and can only be opened by DSN/DS plugs with compatible ratings and contact configurations. DS60 and DSN150 receptacles have a screw-type locking pawl, enabling the user to lock the plug to the receptacle by tightening a screw on the pawl. A lockout hole is included for added security. 800/433-7642; www.meltric.com.
