Phoenix Contact PTV 4-HESILED 24 Fuse Terminal Block with Push-in Connection for 5x20 mm Fuses

The Phoenix Contact PTV 4-HESILED 24 is a high-performance fuse terminal block engineered for industrial applications requiring reliable circuit protection. Featuring advanced Push-in connection technology, this terminal block allows for rapid, tool-free conductor insertion, significantly reducing installation time. It is specifically designed to accommodate 5x20 mm glass tube fuses and includes an integrated LED indicator that provides immediate visual feedback on the status of the fuse during 24V operation, facilitating quick maintenance and troubleshooting in complex control systems.

Advantages

The primary benefit of this terminal block is its efficient Push-in connection system, which ensures a secure and vibration-resistant contact for both solid and stranded wires. By integrating a 24V LED status indicator, the device eliminates the need for external monitoring components, saving valuable space on the DIN rail. The robust design supports high-density wiring configurations, making it an ideal choice for modern control cabinets where space optimization and operational reliability are critical requirements.

Suitable for

• Industrial automation and control systems
• Power distribution panels
• Protection of sensitive electronic equipment
• Systems requiring rapid fault diagnostics

This terminal block may not be suitable for applications involving high-voltage circuits exceeding the specified 24V rating for the LED indicator. Furthermore, it is not intended for use with fuse types other than the standard 5x20 mm glass tube format, and it should not be installed in environments that exceed the thermal or mechanical specifications defined by the manufacturer.

Key specifications

• Connection type: Push-in
• Fuse size: 5x20 mm
• Operating voltage for LED: 24V
• Mounting: DIN rail

To install the Phoenix Contact PTV 4-HESILED 24, simply strip the wire to the required length and insert it directly into the Push-in terminal point until it is firmly seated. The fuse is inserted into the hinged lever mechanism, which allows for safe and easy replacement without the need to disconnect the wiring. Ensure that the circuit is de-energized before performing any maintenance or fuse replacement tasks.

What to consider before purchase

• Verify that your system voltage matches the 24V LED indicator requirements
• Ensure the 5x20 mm fuse size is compatible with your circuit protection needs
• Check available space on your DIN rail for proper installation

For optimal performance and safety, always use the correct fuse rating for your specific application and ensure that all connections are fully seated according to the manufacturer's installation guidelines.
