Fuse base 3P+N 10 x 38 RB 348 005848

Professional fuse base for industrial installations

The 3P+N fuse base has been specifically designed for industrial cylindrical fuses with dimensions of 10×38 mm, offering a reliable solution for circuits with a voltage of 500V~. The design allows for the simultaneous disconnection of the neutral conductor along with the phases, ensuring full circuit separation during service work.

Construction and technical compatibility

The device is mounted on a DIN rail, occupying a standard width of 4 modules. The RAL 7035 color finish guarantees an aesthetic appearance in switchboards. The base is compatible with aM type fuses (motor protection) and gG type fuses (general protection), adapting to various installation requirements.

The design enables a high breaking capacity - 100 kA using 10×38 mm fuses, making it suitable even for installations with significant short-circuit currents. The simultaneous disconnection of the neutral conductor eliminates the risk of voltage appearing on the disconnected circuit.

Operating parameters and safety

The IP20 protection rating provides basic resistance to finger contact and prevents access to hazardous parts. The model is equipped with a locking capability, which prevents unauthorized access to the fuses - crucial for industrial installations requiring access control.

The absence of an optical trip indicator has been compensated for by the simplicity of the design and the ease of fuse replacement. This solution works particularly well in switchboards where frequent access to components is not required.

Application and operational benefits

The base is ideal for use in industrial building switchboards, production machinery, and industrial automation installations. The simultaneous disconnection of all poles (3 phases + neutral) guarantees full separation of the protected circuit - essential during maintenance and service work.

The versatility of DIN rail mounting simplifies installation in existing distribution systems. The compact design (4 modules) allows for efficient space management in the switchboard while maintaining easy service access to replaceable components.
