Eaton Specification Sheet - 571BT4-L1
Brass Pauluhn 571BT4-L1 housing delivers corrosion resistance and robust enclosure protection, supporting IP66-rated sealing in outdoor or damp indoor installations. This reduces maintenance needs and extends service life in harsh environments, safeguarding critical terminations in control cabinets and process panels. The 90° angle design with a flat cover enables compact layouts and easier conduit entry, simplifying installation in tight spaces along walls or equipment frames and reducing overall footprint. The integrated 4-pole terminal block centralizes wiring, minimizes terminal clutter, and improves fault isolation for power distribution in automation booths and machine enclosures. Compatibility with standard 1/2" fittings minimizes adapters and stock variance, lowering total installed costs and speeding maintenance schedules in manufacturing facilities. Surface mounting eliminates extra brackets and fasteners, delivering straightforward, repeatable installations with fewer mounting errors. NEC/CEC compliance paired with IP66 protection guarantees regulatory alignment and rugged performance in ordinary locations, supporting plant modernization projects and reducing design tradeoffs for contractors and OEMs.

FAQs
For optimal performance, install the 571BT4-L1 as a surface-mounted enclosure with the flat cover securely sealed to maintain IP66 protection. Use standard 1/2" fittings compatible with the 4-pole terminal block and ensure the 4.38" length and 2" width fit within the available panel space. Verify mounting surface is flat and capable of supporting approximately 4.2 lb.
Yes. The 571BT4-L1 meets NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations. This makes it suitable for commercial and industrial panels in non-hazardous environments, reducing compliance risk. When planning installations, ensure correct orientation for accessible terminations and maintain IP66 sealing at all entry points.
The enclosure presents 4.38 inches in length/depth and height, with a 2-inch width, and weighs about 4.2 pounds. These dimensions support compact control panels and wall-mounted installations. When planning layouts, account for the 1/2" trade size connections and space needed for a 4-pole terminal block inside the 571BT4-L1.
The built-in 4-pole terminal block centralizes wiring, improving organization and reducing terminal clutter in control circuits. This enhances fault isolation and simplifies field wiring during commissioning. For maintenance, the consolidation reduces spares complexity and expedites terminations in automation cabinets and process equipment.
Brass construction provides corrosion resistance in humid or coastal environments, supporting longer service life. With IP66 sealing and a flat cover design, routine inspections focus on gasket integrity and fastener torque to maintain protection. Regular checks of the 1/2" fittings and 4-pole block ensure continued reliability in industrial operations.
