1557796

Overview

Phoenix Contact part number 1557796 is a ventilation element designed for OCS series outdoor housings. It stabilizes internal pressure differences and reduces condensation without requiring additional operational products. The unit achieves an IP55 protection rating when installed, compatible with NEMA 6P standards. Constructed from UV-stabilized polycarbonate (PC) and PBT, it features a light gray color (RAL 7035). Dimensions are 50 mm width, 50 mm height, and 20 mm depth. Operating ambient temperature ranges from -40 °C to +80 °C. Mounting is performed via screw fixation with a specified torque of 0.9 Nm to 1.1 Nm. The component has no battery compartment or pre-existing ventilation openings.

Feature Summary

• Stabilizes pressure differences within enclosed housing environments
• Reduces condensation formation in outdoor applications
• Maintains IP55 ingress protection integrity upon installation

Applications

• OCS series outdoor enclosure ventilation
• Pressure equalization for sealed electronic housings
• Condensation mitigation in variable temperature environments

Procurement Notes

Verify the specific part number against official Phoenix Contact documentation to ensure compatibility with the intended OCS housing model. Confirm that the required mounting hardware and sealing components are sourced separately, as this ventilation element requires additional products for proper operation. Check technical drawings for precise dimensional fitment before procurement.

Selection Notes

Select this component only if the application requires passive pressure stabilization and condensation reduction within OCS outdoor housings. Ensure the operating environment falls within the specified -40 °C to +80 °C range. Verify that the housing material and design support screw mounting with the recommended torque specifications. Consider UV stability requirements for long-term outdoor exposure.

Part Context

This ventilation element belongs to the Phoenix Contact OCS series accessory line, specifically engineered for outdoor enclosures. It serves as a passive component to maintain environmental integrity within sealed housings. The product is distinct from active ventilation systems and relies on differential pressure mechanisms. It is designed to integrate seamlessly with standard OCS housing configurations without modifying the primary enclosure structure.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing housing models before considering alternative components. Consult official Phoenix Contact catalogs for potential upgrades or legacy replacements.
