## Long description

The Phoenix Contact PT 4-HESI (5X20) is a professional-grade fuse terminal block engineered for secure circuit protection in industrial control cabinets and electrical distribution systems. Designed to accommodate standard 5x20 mm glass or ceramic fuses, this component provides a reliable interface for managing electrical currents up to 6.3 A. Its robust construction and integration into the CLIPLINE complete system ensure compatibility with a wide range of industrial electrical infrastructure.
Advantages
The primary benefit of this terminal block is its advanced push-in connection technology, which facilitates rapid, tool-free wiring for both solid conductors and those equipped with ferrules. The compact design, combined with a front-facing connection layout, allows for efficient installation in confined spaces where panel density is high. Furthermore, the unit includes a double function shaft and an additional test connection, simplifying diagnostic procedures. The terminal block is also certified for use in railway applications, demonstrating its high level of durability and reliability under demanding conditions.
Suitable for
Industrial control cabinet wiring
Electrical distribution systems
Railway and transportation infrastructure
Applications requiring frequent fuse maintenance
This terminal block may not be suitable for high-current applications exceeding 6.3 A or for environments where the fuse size differs from the standard 5x20 mm format. It is also not intended for direct exposure to harsh outdoor elements without an appropriate protective enclosure.
Key specifications
Connection method: Push-in connection
Conductor cross-section: 0.2 mm² to 6 mm² (AWG 24 - 10)
Nominal current: 6.3 A
Nominal voltage: 500 V
Fuse type: 5 x 20 mm (glass or ceramic)
Mounting type: NS 35/7.5 or NS 35/15 DIN rail
Width: 6.2 mm
How to use
To install, mount the terminal block onto a standard NS 35 DIN rail. Insert the conductor into the push-in terminal point until it is securely locked. To insert or replace a fuse, open the hinged lever on the front of the block, place the 5x20 mm fuse into the holder, and close the lever to complete the circuit. Testing can be performed using the integrated test points located in the double function shaft.
What to consider before purchase
Ensure the fuse rating matches your circuit protection requirements.
Verify that the conductor size falls within the 0.2 mm² to 6 mm² range.
Confirm that the DIN rail type (NS 35/7.5 or NS 35/15) is compatible with your existing cabinet layout.
Usage recommendations: Always ensure the power is disconnected before replacing a fuse to prevent accidental contact with live parts. Use appropriate ferrules for stranded wires to ensure a secure and long-lasting connection.
