DDFL4UE220V2A is a high-performance 4 sq.mm Double Level Fuse Terminal Block with 220V LED indication and 2A fuse configuration, specially designed for industrial control panels, automation systems, instrumentation circuits, switchgear assemblies, and electrical protection applications. This terminal block combines the functions of wire connection, fuse protection, and visual fault indication in one compact unit, making it an ideal solution for modern industrial wiring systems where circuit safety and easy troubleshooting are important.
The terminal block features a double-level design, allowing two wiring levels in a compact housing, which helps save DIN rail space and improves panel wiring organization. Its built-in fuse protection circuit protects connected electrical equipment from overload and short-circuit conditions, while the LED indication system provides quick visual status monitoring. In case of fuse failure, the LED indication helps maintenance engineers identify the fault easily, reducing downtime and troubleshooting time in industrial applications.
DDFL4UE220V2A is designed for 220V circuit applications with 2A fuse protection, making it suitable for signal circuits, instrumentation loops, relay circuits, control circuits, and sensitive electrical equipment requiring low-current protection. The terminal block uses a 5 x 20 mm cartridge glass fuse, which is easy to replace during maintenance and provides reliable circuit interruption during fault conditions.
This terminal block supports conductor sizes up to 4 mm² stranded wire and delivers a rated voltage of 800V (IEC) with a rated current of 6.3A, ensuring safe electrical performance in industrial wiring systems. It also meets international electrical standards with UL/CSA voltage rating of 600V and is suitable for global industrial panel applications.
The terminal uses screw clamp connection technology, providing strong mechanical clamping and low contact resistance for reliable electrical continuity. Its M3 screw clamp system with 0.5 Nm tightening torque ensures secure wire holding and vibration-resistant performance in demanding industrial environments. The side wire entry orientation allows easy conductor insertion and neat cable routing inside control panels and electrical cabinets.
Manufactured using high-quality Polyamide insulating material, DDFL4UE220V2A offers excellent insulation strength, flame resistance, and long service life. The terminal block also provides 5kV rated surge voltage protection, improving safety against transient voltage spikes in industrial electrical systems.
Its compact DIN rail mountable design, integrated fuse protection, LED fault indication, and reliable screw clamp connection make DDFL4UE220V2A an ideal choice for industrial electricians, panel builders, automation engineers, and OEM manufacturers looking for safe and space-saving circuit protection solutions.
