Rittal 5302027 Central Earthing Point - EN 50 310
Part Number: 5302027
Quick Summary
Central earthing point 5302027 provides a reliable frame-to-network connection for VX IT enclosures. Without a central point, achieving consistent potential equalisation across components can be time-consuming and error-prone. Key standards include DIN EN 50 310 for central earthing, ETIM 9 EC001503, and ECLASS 8.0 27149219 to support data integration and procurement processes. This solution offers a compact, easy-to-install kit that integrates with RBC connections on enclosure frames, improving reliability and compliance. By standardising bonding across doors and panels, it reduces wiring complexity and supports scalable IT enclosure deployments.
Product Information
Extended Description
5302027 Rittal: Potential equalisation kit for VX IT, to establish seamless central potential equalisation between all installed components and/or to ensure functional earthing in accordance with DIN EN 50 310
Article number
DK 5302.027
Product description
Central earthing point on the enclosure frame for simple connection of the enclosure to the earthing/potential equalisation network (rack bonding conductor (RBC) connection point).
Applications
To create seamless central potential equalisation between all installed components and/or to ensure functional earthing to EN 50 310
Function principle
Contact between all enclosure panels and the enclosure frame as central earthing point plus contact with all installed components to the same potential, via a conductive attachment or separate earth strap

Product description
Potential equalisation kit for VX IT, to establish seamless central potential equalisation between all installed components and/or to ensure functional earthing in accordance with DIN EN 50 310
Feature: Central earthing point mounted on the enclosure frame provides a dedicated bonding interface. Business Impact: Enables seamless potential equalisation across all installed components, reducing stray voltages and improving functional earthing. Application: VX IT enclosure systems requiring reliable RBC connections. Feature: 0.3 m long earthing lead simplifies routing and attachment to the rack bonding conductor network. Business Impact: Cuts installation time and minimizes miswiring risk. Application: Fast, repeatable bonding during panel assembly. Feature: Supplied with seven earth straps (4 mm²), UL style 1015 AWG 12, for doors and optional side panels. Business Impact: Robust, compliant bonding across multiple panels reduces maintenance needs and costly rework. Application: Multi-panel enclosure configurations. Feature: Central earthing point plus assembly parts included. Business Impact: Streamlines procurement and on-site assembly, lowering total installed cost. Application: VX IT and similar rack-mounted systems. Feature: Note on risk assessment — if approved, protective earthing measures may not be required. Business Impact: Simplifies safety planning and accelerates commissioning. Application: Regulated environments with qualified electricians. This kit also aligns with ETIM and ECLASS classifications for easy data exchange and procurement workflows.

FAQs
The kit mounts on the enclosure frame as a central earthing point and uses the supplied 0.3 m earthing lead to connect to the RBC network. Doors and optional side panels receive bonding through the seven earth straps (4 mm², UL style 1015 AWG 12). Assembly parts are included, simplifying on-site installation and reducing project lead times.
The DK 5302.027 kit is designed to establish a seamless potential equalisation in accordance with DIN EN 50 310, ensuring functional earthing for VX IT enclosures. It aligns with ETIM 9 EC001503 and ECLASS 8.0 27149219 classifications to support data-driven procurement and interoperability.
While tailored for VX IT, the central earthing principle—a frame-mounted bonding point with a short lead and multi-panel straps—is adaptable to similar enclosure families that require central potential equalisation. Confirm clearance and RBC connection compatibility with your specific enclosure before deployment.
Key factors include correct routing of the 0.3 m earthing lead, secure attachment of all seven earth straps on doors and side panels, and ensuring the central earthing point remains clean and conductive. If a qualified electrician performs a risk assessment and identifies no extended risk, protective earthing measures may not be required, streamlining compliance.
The kit reduces wiring complexity by providing a single central bonding point, shortening commissioning time and decreasing potential miswiring faults. Ongoing maintenance is simpler due to unified bonding across panels, lower fault potential differences, and easier diagnostics for enclosure-based systems in VX IT deployments.
