Load Centers up to 250 A

Product catalog summary
Overview: The document provides comprehensive information on ENYSTAR Load Centers, designed for commercial and industrial buildings, focusing on systems up to 250 A in compliance with IEC 61439-3 standards. Manufactured by HENSEL, these systems are known for their reliability in electrical distribution.
System Description: ENYSTAR Load Centers are modular distribution board systems featuring a pre-assembled vertical busbar system. They are designed to be dust-proof and water-protected (IP 66) with high impact resistance (IK 08), suitable for harsh environments and compatible with devices from various manufacturers.
Key Specifications:
  • Rated Voltage: Max 690 V a.c.
  • Rated Insulation Voltage: 690 V a.c., 1000 V d.c.
  • Rated Current: Max 250 A
  • Rated Short-time Withstand Current: Max 7.2 kA
Product Overview: Various configurations of load centers are outlined, including options for isolator/MCB/RCCB or RCBO up to 125 A, and MCCB up to 250 A. Each configuration offers transparent or opaque doors and detailed specifications for modules, terminals, and installation dimensions.
Accessories: A range of accessories is available, such as connection boxes, sealing devices, closing plates, flanges for cable entry, and ventilation flanges, facilitating installation and ensuring compatibility with diverse requirements.
Technical Details: Comprehensive technical details are provided, including installation dimensions, rated voltages, and current withstand capabilities, ensuring the load centers meet specific operational and environmental conditions.
Conclusion: ENYSTAR Load Centers are robust and versatile, designed to meet the demanding needs of commercial and industrial electrical distribution. They offer flexibility in configuration and compatibility with a wide range of devices, suitable for various applications in harsh environments.
Ventilation Components: Two types of ventilation flanges are described for vertical installation on box walls to prevent high internal temperatures and water condensation, each with two fixing elements.
Operating and Ambient Conditions: Suitable for indoor and protected outdoor installations, with ambient temperatures averaging +35°C over 24 hours, max +40°C, min -5°C, and relative humidity up to 100% at 25°C.
Fire Protection and Standards: Fire protection requirements include glow wire tests at 650°C for boxes and 850°C for conducting components, with standards such as IEC 60695-2-11, IEC 61439-3, and IEC 60529.
Installation Instructions: Detailed instructions for installing circuits, using mounting plates and DIN rails, with specified dimensions and adjustments for installation equipment.
Current Ratings and Power Dissipation: Circuits should not exceed 80% of the installation equipment's rated current. Power dissipation must be calculated to ensure it does not exceed the enclosure's capacity, with provided formulas and tables for determining power dissipation and rated diversity factors (RDF).
Terminal Technology: Specifications include types of conductors, cross-sections, tightening torques, and current carrying capacities for cables, emphasizing the use of end ferrules for flexible conductors.
Contact Information: The document concludes with contact details for Gustav Hensel GmbH & Co. KG, the manufacturer of the ENYSTAR distribution boards.
