Product Description

The KILLARK SWB-17 is an explosion proof junction box designed for use in hazardous location electrical installations. Built to contain any internal ignition and prevent it from propagating to a surrounding flammable atmosphere, this enclosure is a core component in industrial wiring systems where combustible gases, vapors, or dusts may be present. The SWB-17 features a 1-1/4 inch conduit entry and weighs 4.56 pounds, indicating a heavy-duty cast construction consistent with KILLARK hazardous location products. Licensed electricians and industrial maintenance professionals are the primary installers of this type of enclosure.

This explosion proof junction box is suited for use in industrial and commercial facilities classified as hazardous locations under NEC Article 500, including oil and gas processing areas, chemical plants, petrochemical facilities, wastewater treatment plants, and similar environments where ignition-capable electrical enclosures are required. The 1-1/4 inch conduit hub size makes it compatible with standard rigid or IMC conduit runs in these installations.
