Fuse base, 1-pole design, cable terminals: screw M12. PBD 3 Un: 690 V~ In: 630 A 63-820998-011

Fuse base – solid protection for electrical installations

This 1-pole fuse base, designed to work with blade fuses, is a key element in protecting electrical circuits in industrial installations and public buildings. Made of high-quality materials, it ensures reliable operation and long life. M12 screw terminals guarantee a secure and durable connection of wires, even with a large cross-section, up to 500 mm².

Functionality and technical parameters

The PBD 3 base is designed to operate in systems with a rated voltage of 690 V AC and a rated current of 630 A. Its construction, compliant with size NH3, allows the installation of fuse links with appropriate parameters, adapted to the specifics of the protected installation. The short-circuit withstand current reaches 65 kA, which ensures effective protection against the effects of sudden overvoltages and short circuits. The device is also characterized by high mechanical durability – it withstands as many as 250 operating cycles.

Installation and application

The PBD 3 fuse base is an ideal solution for both professional installers and end-users looking for reliable protection of their electrical installations. Thanks to its simple installation and versatility, it finds wide application in:

• Electrical distribution boards
• Control cabinets
• Industrial installations
• Public buildings
• Machine and equipment power systems
• Protection against overloads and short circuits in electrical circuits.

It is important to select the appropriate fuse link, taking into account the load characteristics and the requirements for disconnection time.
