The CYDLGF4LR is a premium double-level fuse terminal block with grounding connection designed for industrial electrical control systems, automation panels, switchgear assemblies, instrumentation circuits, and machine wiring applications. This advanced terminal block combines fuse protection, feed-through wiring, grounding functionality, and lateral equipotential connection points, making it an efficient and space-saving solution for complex electrical panel applications.
In modern industrial electrical systems, panel builders often require multiple functions in a compact terminal block—such as circuit protection, grounding, organized wiring, and potential distribution. The CYDLGF4LR is specifically designed to meet these requirements by integrating several electrical functions into a single compact DIN rail-mounted component. This reduces panel wiring complexity, improves installation efficiency, and optimizes cabinet space utilization.
The CYDLGF4LR belongs to the CY Series screw clamp fuse terminal block family and is engineered for industrial applications requiring 5 x 20 mm or 5 x 25 mm cartridge fuse protection. The upper level contains a hinged fuse carrier for circuit protection, while the lower level provides a feed-through terminal connection for wiring continuity. In addition, the “G” version includes a ground/earth connection point, and the “LR” version offers equipotential lateral connection joints on both sides, allowing flexible distribution and interconnection of same-potential circuits.
Built with high-grade Polyamide 6.6 insulation, the CYDLGF4LR offers excellent electrical insulation, heat resistance, mechanical durability, and long service life. The screw clamp termination system provides gas-tight and vibration-resistant wire connections, ensuring stable electrical performance even in demanding industrial environments. This reduces the risk of loose wiring, electrical arcing, overheating, and system failure.
The compact double-level design makes the CYDLGF4LR ideal for applications where panel space is limited. Instead of using separate fuse terminals, grounding terminals, and feed-through terminals, this integrated design helps reduce component count and improve panel organization. This makes it especially useful in high-density industrial control cabinets.
The CYDLGF4LR supports wire sizes from 0.2 mm² to 4 mm² (24–10 AWG) and is typically rated for 10A current capacity with 1000V IEC voltage rating depending on application standards. The screw clamp mechanism ensures secure conductor retention, while the fuse protection system helps safeguard sensitive circuits against overloads and fault conditions.
This terminal block is widely used in:
With its integrated fuse protection, grounding point, feed-through connection, and lateral bridging functionality, the CYDLGF4LR provides engineers and panel builders with a reliable, safe, and space-efficient electrical terminal solution for modern industrial applications.
