Phoenix Contact UK 5-HESI Fuse Terminal Block, Black

The Phoenix Contact UK 5-HESI is a professional-grade fuse terminal block designed for secure circuit protection in industrial control panels and electrical installations. This black terminal block features a robust design for reliable wire connection and easy fuse replacement. It is engineered for high-performance electrical distribution, ensuring safety and efficiency in demanding automation and power management applications.

Advantages

The terminal block offers a highly reliable screw connection method that ensures secure contact for wires ranging from 0.2 mm² to 4 mm². Its design includes a safety lever that locks firmly in the end position, preventing accidental opening and ensuring consistent circuit integrity. The unit is built for versatility, supporting various fuse types including glass and ceramic variants, and features a large surface area for clear labeling to facilitate organized maintenance and identification within complex control cabinets.

Suitable for

• Industrial control panels
• Electrical distribution systems
• Automation and power management
• Protection of control circuits

When it may not be suitable

This terminal block is not intended for high-current applications exceeding 6.3 A, as it is specifically rated for lower-current protection. It is also not suitable for environments requiring specialized hazardous area certifications unless explicitly stated for those specific conditions.

Key specifications

• Connection method: Screw connection
• Cross section: 0.2 mm² to 4 mm² (24 - 12 AWG)
• Nominal current: 6.3 A
• Nominal voltage: 800 V
• Fuse compatibility: G / 5 x 20 / 5 x 25 / 5 x 30
• Mounting type: NS 35/7,5, NS 35/15, NS 32
• Width: 8.2 mm

How to use

To install, mount the terminal block onto a standard DIN rail (NS 35 or NS 32). Insert your conductors into the screw terminals and tighten them to the specified torque to ensure a secure electrical connection. To insert or replace a fuse, lift the safety lever, place the appropriate glass or ceramic fuse into the holder, and close the lever until it locks into the end position.

What to consider before purchase

• Ensure the fuse type matches your specific circuit requirements.
• Verify that the wire gauge falls within the 0.2 mm² to 4 mm² range.
• Check available space on the DIN rail, noting the 8.2 mm width.
• Confirm that the nominal current of 6.3 A is sufficient for your application.

Usage recommendations

Always ensure the power is disconnected before replacing a fuse to prevent electrical shock. Use appropriate tools for screw tightening to avoid damaging the terminal block housing.
