Product Description

DDFL4UBU is a double level fuse terminal block designed for secure electrical connection, circuit protection, and organized panel wiring in industrial electrical systems. It combines the functions of a fuse protection circuit and feed-through connection in one compact terminal block, making it an ideal solution for applications where safe electrical connection and overload protection are required in a single component. This dual-function design reduces the need for separate fuse and feed-through terminals, helping save DIN rail space and improve panel efficiency.

The main function of DDFL4UBU is to provide wire termination along with integrated fuse protection for sensitive control and signal circuits. In case of overload or fault current, the fuse interrupts the circuit and protects connected electrical components from damage. At the same time, the lower feed-through level provides reliable conductor continuity for organized panel wiring. This makes it highly suitable for control panels, PLC systems, instrumentation circuits, switchgear assemblies, relay panels, automation systems, machine wiring, and industrial electrical installations.

One of the major advantages of DDFL4UBU is its double level compact construction, which combines two functions in one terminal block and helps save valuable panel space compared to using separate fuse and feed-through terminal blocks. This compact design improves wiring density and creates a cleaner, more organized electrical panel layout in industrial applications.

Its integrated 5 x 20 mm fuse carrier provides reliable circuit protection, while the lower feed-through level supports secure conductor continuity and stable current transfer. The screw clamp connection system ensures strong conductor retention, low contact resistance, and reliable long-term electrical performance in industrial operating conditions. The blue colour housing supports quick circuit identification and organized colour-coded panel wiring layouts.

Manufactured using high-strength engineering-grade polyamide insulated housing with industrial-grade conductive components, DDFL4UBU provides excellent electrical insulation, mechanical durability, heat resistance, secure wire holding, and long service life in demanding industrial environments. Its DIN rail mountable compact design supports fast installation and efficient panel assembly in modern electrical systems.


★ Why DDFL4UBU Is Used

DDFL4UBU is used in electrical systems where wire connection and circuit protection are required together in one compact terminal block. It protects electrical circuits from overload conditions while providing safe and organized wiring in industrial panels.

★ Key Benefits

Provides fuse protection for sensitive circuits
Combines connection and protection in one unit
Saves panel space with double level design
Improves wiring organization
Reduces equipment damage risk
Supports safe industrial electrical systems


★ Functional Working Design

DDFL4UBU works by combining a screw clamp terminal connection with an integrated fuse holder. Conductors are connected securely through screw clamp terminals, while the fuse installed inside the terminal protects the circuit against overcurrent.

When current exceeds the fuse rating, the fuse interrupts the circuit automatically, preventing damage to connected devices. The upper fuse level provides protection, while the lower feed-through level maintains continuous wiring connection, improving panel efficiency and reducing component count.
