What is a PRESTAB panel?
PRESTAB is a wall-mounted empty enclosure and cabinet system developed for low-voltage power distribution, control, and automation applications. Thanks to its welded monoblock structure, it offers a durable, long-lasting, and practical solution.
Which standard do PRESTAB panels comply with?
PRESTAB panels have been developed in accordance with the IEC 61439-2 standard for low-voltage switchgear and controlgear assemblies. The system offers a rated voltage of 400 V AC and an operating voltage of up to 690 V.
What are the size options for PRESTAB cabins?
PRESTAB cabinets are available in widths of 200–1200 mm, heights of 300–1400 mm, and depths of 150–400 mm. These varied dimensions allow the cabinet to be configured according to the project’s equipment layout and installation space.
What is the protection class of PRESTAB panels?
The PRESTAB enclosure family offers protection class options of IP31, IP43, IP55, and IP66. Thanks to its monoblock welded body, suitable door design, and sealing structure, it can provide protection against dust and water up to the IP66 level.
Can PRESTAB panels be used outdoors?
Yes. PRESTAB panels can be configured for both indoor and outdoor use. For outdoor applications, factors such as temperature, humidity, precipitation, dust, and corrosion must be considered alongside the IP protection rating.
What are the current and short-circuit withstand ratings of PRESTAB panels?
The PRESTAB panel system supports an operating current of up to 630 A. The busbar short-time withstand current can reach up to 50 kA, and the busbar peak withstand current up to 110 kA. Exact values must be determined based on the selected panel configuration.
Which materials are used in PRESTAB panels?
The PRESTAB enclosure frame and mounting plates are manufactured from galvanized steel. Electrostatic powder-coated steel is used for the doors and covers. The standard color is RAL 7035, and the cabinet offers IK10 mechanical impact protection.
Where are PRESTAB panels used?
PRESTAB wall-mounted enclosures are suitable for use in factories, production facilities, commercial buildings, power distribution systems, machine automation, control applications, and infrastructure projects. Thanks to their wall-mounted design, they offer a suitable solution for projects where floor space is limited.
