REQUEST A QUOTE Custom Stainless Enclosures, Inc. » 4Xxtreme® Series Enclosures » Flanged Disconnect Enclosures What is a Disconnect Enclosure and Why is it Essential for Safety? A Flanged Disconnect Enclosure is a specialized safety housing designed to contain electrical disconnect switches in sanitary washdown environments. A flanged design physically interlocks with your main control panel. This ensures that the main enclosure door cannot be opened unless the power is disconnected, providing a critical fail-safe layer of protection. These enclosures not only protect the disconnect switch from high-pressure water and harsh cleaning chemicals but also safeguard personnel by preventing accidental contact with live electrical components during maintenance. The disconnect switch is a crucial component in electrical systems, particularly in wet or hazardous production areas. A disconnect enclosure serves four key functions: Enhanced Personnel Safety: The flanged interlock system forces a “safety-first” workflow, ensuring the operator cannot access the main panel without cutting power. This significantly reduces the risk of electrical shock. Regulatory Compliance: Meeting safety regulations (such as NEC and OSHA) and sanitary standards (FSMA) is essential. Our enclosures help you remain compliant with both electrical safety and food safety inspections. Emergency Isolation: In the event of a machine fault or safety incident, the external disconnect provides a quick, accessible, and visible way to shut down power immediately, preventing accidents and equipment damage. Maintenance Efficiency & Arc Flash Mitigation: A dedicated disconnect enclosure facilitates routine maintenance by providing a clear isolation point. When upgraded to a Sequestered configuration, it further isolates line-side voltage to mitigate Arc Flash risks, potentially lowering the PPE requirements for your maintenance team. Our Enclosures Shop Our Standard Enclosures 4Xxtreme® Series Custom Enclosures 4XProtect® Series Enclosures Available Disconnect Enclosure Configurations Custom Flanged Disconnect Enclosures Our core line of disconnect enclosures is available in multiple door arrangements to fit any control system size. Single Door: Compact and efficient for standalone machine control. Double Door: Expanded capacity for larger panels. Multi-Door (3+): Designed for complex, high-capacity systems where organization is key. Resources: Single-Door Flanged Disconnect Data Sheet Multi-Door Flanged Disconnect Data Sheet Custom Sequester External Enclosures (Arc Flash Isolation) For the highest level of safety, upgrade to our Sequester box technology. This isolates the main power disconnect in a separate compartment, keeping the main panel completely de-energized and safe to access without heavy PPE. Enclosure Package: Order a complete system featuring a main enclosure permanently joined to a sequester box via our hygienic flange. Standalone Sequester Box: Order the sequester box separately to retrofit or attach to your existing disconnect enclosure setup. Feature Highlight: Our sequester units feature a Removable Center Post, making installation of heavy disconnect switches faster and easier.

Enclosures for All Industries A solution that meets the demands of all industries maintaining optimal performance and reliability. From heavy industry to high-tech laboratories, our enclosures are designed to meet the unique challenges of your electrical equipment. Locations of disconnects and requirements for proper disconnect spacing are determined by the purchaser. Consult Space Occupied by Disconnect drawing to determine whether or not the disconnect device you are using will fit the enclosure size that you have selected for the application. Refer to the current National Electrical Code 2008 article 430.10(B) for wiring space required for the size of conductors to be connected to disconnect. Always verify your application to determine if the wiring space is adequate before drawing approvals. Custom Stainless Enclosures, Inc. is not responsible for verifying flange design, with customer’s disconnect and or enclosure sizes.
