The nVent HOFFMAN 89123101SP is a cover assembly designed for N21 series enclosures. It is constructed from 304 stainless steel to provide durable protection for internal components in demanding environments. The unit includes an integrated side filter to maintain environmental sealing while allowing necessary airflow. This component is RoHS compliant, ensuring adherence to restricted substance regulations. It serves as a replacement or accessory part for maintaining the integrity of industrial electrical and electronic enclosure systems.
Verify that the target enclosure belongs to the N21 series before procurement, as this cover is model-specific. Confirm that the required material is 304 stainless steel rather than other grades. Ensure that the existing enclosure frame supports the integrated side filter configuration included with this assembly. Check for RoHS compliance requirements if the application involves strict regulatory standards.
Select this part when replacing a damaged cover on an N21 series unit where stainless steel durability is required. Consider the integrated side filter feature if enhanced air filtration is needed without compromising the seal. Evaluate whether 304 stainless steel offers sufficient corrosion resistance for the specific installation environment compared to alternative materials.
This component is part of the nVent HOFFMAN N21 series accessory lineup. It functions as a structural and protective element for larger enclosure assemblies. The product falls under the broader category of industrial enclosure spare parts and accessories designed to extend equipment lifespan and maintain safety standards in electrical installations.
Confirm exact fitment with the specific N21 enclosure model number. Verify that the mounting points align with the existing frame structure. Ensure no modifications are required for the side filter integration.
