Description

The 21000-28-05-30-030-04-02 is a CSA-certified explosion-proof housing assembly optimized for moderate-clearance industrial applications. Combining a 3-inch standoff and 3-inch penetration, this configuration balances spatial isolation and component access in hazardous environments. Includes a 0.5 m (20 in) integrated triaxial cable and 3/4-14 NPT plug for simplified field integration.
