Industrial Bus Plug Enclosure

The Wiegmann SSN4201606 is a wall-mount enclosure built from 304 stainless steel with a smooth grained finish. It provides a solid, padlockable cover secured by clamps and a poured-in-place polyurethane gasket. The unit carries NEMA 12, 3R, 4, 4X and IP66 ratings plus cULus, CSA and IEC certifications. It suits installers who need a corrosion-resistant housing for bus plug components in wet or dusty environments.

Sustained Load Behaviour

The 14-gauge steel body and seamless gasket maintain their seal during continuous operation in harsh conditions. Hinged cover access allows inspection without removing the enclosure from the wall. Internal panel 2W828 supports fixed bus plug assemblies that do not generate cyclic vibration. The enclosure is not suited for applications requiring active cooling or forced-air throughput.

Thermals Noise and Power

Passive construction means no fans, no moving parts and zero acoustic output. The stainless steel shell dissipates heat from installed devices through natural convection across its 20 by 16 by 6 inch footprint. External mounting feet keep the rear surface clear for airflow. No power draw originates from the enclosure itself.

Questions about this item

Does the 304 stainless steel enclosure dissipate heat adequately when a bus plug runs continuously inside?

The 14-gauge 304 stainless steel body with a seamless poured-in-place gasket provides a solid thermal path; NEMA 4X and IP66 ratings confirm the seal stays intact during extended operation.

What mounting hardware or interior panel must I already have to install the SSN4201606?

The enclosure includes external mounting feet for wall mounting and accepts the 2W828 interior panel, which is listed as the matching panel for this series.

Will the hinged clamp cover and padlock hasp on this 20×16×6 inch unit interfere with older bus-plug brackets I want to reuse?

The hinged solid cover secures with clamps and a padlockable hasp, while the external mounting feet keep the same wall footprint, so existing brackets typically align without modification.
