Killark SWB-1 Explosion Proof Junction Box 1/2 Inch

Product Description

The KILLARK SWB-1 is an explosion-proof junction box designed for use in hazardous location electrical installations. Built to contain any internal ignition and prevent the propagation of flame or explosion to the surrounding atmosphere, this box is a core component in classified-area wiring systems. The SWB-1 features a 1/2 inch conduit entry and compact form factor suited for tight enclosure layouts. It is typically installed by licensed electricians working in Class I or Class II hazardous environments such as petrochemical facilities, grain handling operations, and industrial processing plants.

The SWB-1 is used in fixed electrical installations where conduit systems must maintain explosion-proof integrity throughout. It fits residential or light commercial work is not the typical context here. This box is specified for industrial and heavy commercial projects where the National Electrical Code (NEC) requires listed explosion-proof enclosures for junction and splice points in classified areas. The compact dimensions make it adaptable to panel layouts and conduit runs where space is limited.

Key Features

• Explosion-proof construction rated for hazardous location service
• 1/2 inch conduit entry for standard trade-size conduit connection
• Compact enclosure dimensions suitable for tight conduit system layouts
• Designed for use in NEC-classified hazardous areas requiring listed enclosures

Compatibility

Designed as an OEM-style explosion-proof junction box for use in hazardous location conduit systems requiring 1/2 inch entry fittings.

Installation Notes

Installation must be performed by a licensed electrician familiar with NEC Article 500 requirements for hazardous locations. De-energize and lock out all circuits before opening or installing explosion-proof enclosures. All conduit connections must be made with listed explosion-proof fittings and maintained to the required thread engagement to preserve the enclosure's explosion-proof rating. Do not use this enclosure in applications requiring a higher conduit trade size without confirming the appropriate listed fitting is used.
