Distribution box equipped with 3F sockets and TH-35 busbars IP54 RB-3

Construction distribution box with 3F sockets and TH-35 rails

This construction distribution box from KARWASZ (model RB-3) is a reliable solution for powering machines and equipment on construction sites, in workshops, and in harsh industrial conditions. It provides safe and convenient connection for both single-phase and three-phase devices. A solid construction and high IP54 protection class guarantee long-lasting and trouble-free operation even in demanding environments.

Functionality and application

The RB-3 distribution box has been designed with practicality and versatility in mind. It is equipped with a number of sockets that allow you to connect various equipment:

• Two 1-phase 3x16A sockets – ideal for powering hand tools, lighting or small devices.
• One 3-phase 5x16A socket – dedicated to devices requiring higher power consumption.
• One 3-phase 5x32A socket – designed to power heavy construction or industrial equipment.
• TH-35 rails – allow mounting additional protection devices (circuit breakers, RCDs) to adapt the distribution box to specific installation needs.

The housing made of galvanized sheet metal provides corrosion and mechanical damage resistance, which translates to a long service life. A lock in the door protects against unauthorized access to the inside of the distribution box.

Construction and characteristic features

The construction of the distribution box has been designed for easy installation and use. IP54 protection class protects against dust and water splashes, allowing operation in difficult weather conditions. A durable housing made of galvanized sheet metal protects internal components and increases resistance to mechanical damage. This enables safe operation even in demanding construction or industrial conditions.
