304 stainless steel construction with a 14-gauge wall delivers exceptional corrosion resistance and robust protection in washdown areas. In maintenance-heavy environments, this design reduces replacement cycles and downtime, lowering total ownership costs for food and beverage processing, chemical plants, and outdoor control panels. NEMA 4X protection provides reliable ingress resistance against water, dust, and corrosive exposure in outdoor or harsh indoor settings. The oil-resistant gasket complements the metal enclosure to maintain integrity during frequent washdowns and chemical contact. Surface mounting with external feet accelerates installation and simplifies multi-panel or retrofit layouts. This approach also supports easier alignment, leveling, and secure mounting in tight spaces. Removable cover, recessed pull ring, and stainless screws enable fast maintenance without compromising protection. Operators can access wiring and components quickly for inspections, testing, or replacement while keeping the enclosure sealed between service events. Compact dimensions—9.5 in tall, 8.5 in wide, 3 in deep—and a light 7.2 lb weight support efficient relocation and reconfiguration across facilities.

FAQs
The PB9-4XS is surface-mounted with external mounting feet, enabling quick, secure installation on wall surfaces or panel backs. This setup simplifies alignment across multi-panel configurations, reduces installation time, and allows easy retrofitting in tight spaces. The external feet also facilitate leveling and compatibility with a range of mounting surface thicknesses, which is particularly valuable in retrofit projects or crowded electrical rooms.
Performance in washdown environments is enhanced by the 304 stainless steel construction and a 14-gauge wall, delivering superior corrosion resistance and structural integrity. The oil-resistant gasket further protects against moisture ingress, while the hinged screw cover and removable lid provide reliable access for maintenance without compromising enclosure protection. These features together reduce maintenance cycles and extend service life in harsh chemical and washdown applications.
Yes. The PB9-4XS is designed for outdoor and harsh indoor settings thanks to its NEMA 4X protection and corrosion-resistant 304 stainless steel body. This makes it well-suited for outdoor control panels, hazardous plant areas, and facilities with frequent washdowns or chemical exposure, while maintaining a robust, accessible operator interface.
Maintenance considerations include monitoring the integrity of the oil-resistant gasket to ensure sealing performance after repeated washdowns, inspecting the removable lid and hinge for smooth operation, and using the recessed pull ring for easy access during inspections. The stainless screws resist corrosion, supporting longer service intervals and reducing maintenance labor in tough environments.
The PB9-4XS measures 9.5 in high, 8.5 in wide, and 3 in deep, with a weight of about 7.2 lb. These compact, lightweight dimensions simplify installation in space-constrained panels and facilitate reconfiguration across multiple lines or retrofit projects. The size and weight also ease handling during field mounting and reduce the need for heavy lifting equipment on site.
