CYF4L10-36V

Product Description

The CYF4L10-36V is a 4 sq.mm single-level fuse terminal block with LED indication, specially designed for industrial electrical systems where circuit protection, fuse monitoring, fault indication, and structured conductor termination are required in one compact terminal block. This terminal block is widely used in PLC control panels, automation systems, instrumentation panels, machine wiring, switchgear assemblies, and industrial electrical control cabinets where sensitive electrical circuits require fuse-based protection along with quick visual fault indication.

In industrial electrical systems, control circuits, signal wiring, instrumentation loops, and auxiliary power lines often require protection against short circuits, overload conditions, and abnormal fault current flow. Traditional fuse holders may provide protection, but technicians often face difficulty identifying a blown fuse quickly. The CYF4L10-36V solves this problem by combining a fuse protection terminal with integrated LED indication, allowing both conductor termination and fault monitoring in one compact unit.

One of the key advantages of the CYF4L10-36V is its LED fuse blow indication system, specially designed for 10-36V operating indication range. When the fuse fails, the LED indication helps technicians identify the faulty circuit quickly without manually checking each fuse. This improves maintenance speed, reduces troubleshooting time, and supports better panel monitoring in industrial systems.

The terminal block accepts standard 5 x 20 mm and 5 x 25 mm cartridge fuses, making it suitable for industrial control and signal protection applications. The fuse interrupts the circuit during overload or short circuit conditions, protecting connected devices such as:

• PLC I/O circuits
• Sensors
• Relay circuits
• Instrumentation systems
• Control panels
• Signal circuits
• Auxiliary power circuits
• Machine control wiring
• Automation systems
• Electrical protection panels

Another major feature of the CYF4L10-36V is its screw clamp conductor connection system, which provides secure conductor retention and stable electrical continuity. The screw clamp technology ensures:

✔ Strong conductor grip
✔ Low contact resistance
✔ Stable current transfer
✔ Vibration-resistant connection
✔ Long-term electrical reliability

Its single-level compact fuse terminal design combines fuse protection and conductor connection inside one modular terminal block, reducing the need for separate inline fuse holders and external fault monitoring accessories. This improves:

✔ Cleaner panel wiring
✔ Better space utilization
✔ Faster maintenance access
✔ Organized circuit protection
✔ Professional panel finishing

The side wire entry design improves cable routing and makes conductor insertion easier in compact electrical panels. The enclosed fuse holder construction improves operator safety by reducing accidental contact risk during servicing.

Its DIN rail mounting compatibility makes installation simple inside industrial electrical cabinets and modular terminal block assemblies. The compact body allows high-density panel mounting in control and automation systems.

The terminal block is manufactured using industrial-grade polyamide insulated housing, which provides:

✔ High insulation strength
✔ Heat resistance
✔ Mechanical durability
✔ Corrosion resistance
✔ Safe electrical protection

This rugged construction supports stable operation in industrial environments affected by:

• Heat
• Dust
• Mechanical vibration
• Continuous electrical load
• Maintenance-heavy industrial systems

Because of its fuse protection function, LED blow indication, compact DIN rail design, secure conductor connection, and industrial-grade durability, the CYF4L10-36V is widely used in modern industrial electrical systems where safe circuit protection and quick fault identification are essential.
