Surface-mounted distribution board RH-4 IP54 with 400x500x195 plate

Professional hermetic distribution board for surface-mounted installations

The RH-4 distribution board is a complete solution for electrical installations requiring high protection against environmental conditions. Thanks to the IP54 protection class, it provides an effective barrier against dust and moisture, making it an ideal choice for both professional installers and end users seeking reliable equipment.

Construction and materials

The enclosure of the distribution board is made of galvanized sheet metal, which is characterized by natural corrosion resistance. The surface is coated with powder paint in grey RAL 7035, guaranteeing an aesthetic appearance and additional protection against atmospheric factors. The device dimensions of 400×500×195 mm provide optimal mounting space while maintaining a compact form.

The design is equipped with a cable gland system, which allows for the safe entry of cables into the interior of the distribution board and ensures the tightness of the connection. The hermetic lock guarantees a durable closure of the door and maintains the protection parameters throughout the entire service life.

Equipment and mounting capabilities

The standard set includes a mounting plate, which serves as a solid base for installing electrical devices such as circuit breakers, residual current devices, or other modular devices. The plate allows for flexible component placement according to individual installation needs.

The distribution board features an N neutral terminal block with nine holes, each suitable for conductors with a cross-section up to 16 mm². This solution simplifies the routing of neutral installations and ensures safe electrical connections. The full door protects the contents from accidental access and the influence of external factors.

Operating parameters and safety

The device operates at a rated voltage of Uni 500 V and a nominal current of Inc 63 A, allowing for wide application in various electrical installations. The IP54 protection class means total resistance to dust and protection against water jets from any direction.

The design meets the safety standard requirements for hermetic distribution boards, ensuring reliable operation in both industrial and residential conditions. The sealing system guarantees the maintenance of protection parameters even with intensive door operation.
