Product Information
Full details
This Phoenix Contact ST Fuse Clamp (3036369) is designed for electrical engineers and technicians requiring reliable fuse protection and versatile potential distribution in a compact DIN rail mountable unit. Its key benefit lies in its user-friendly spring clamp terminals and integrated fuse holder, simplifying wiring and maintenance. A potential caveat is the specific fuse size requirement (5x20mm). Key features include generous connection space, a compact design, two function shafts for flexible potential distribution, and skip-through connection capability.

FAQs
What type of fuse does this terminal block use?
This terminal block uses a 5x20 mm G-fuse with a rated current of 6.3A.
What is the maximum conductor size I can connect?
For solid-core conductors, the maximum connectable cross-section is 6 mm². For fine-strand and multi-wired conductors, the maximum is 4 mm².
Can I use this for both power and signal wiring?
Yes, its versatility allows for both power distribution and signal wiring, provided the voltage and current ratings are not exceeded. The integrated fuse offers protection for sensitive components.
How do I create multiple connections from a single input?
You can utilize the two function shafts and the skip-through connection feature for potential distribution. Busbars or jumper elements can be used in the function shafts to bridge multiple terminals.
What are the dimensions of this terminal block?
The width/grid dimension is 6.2 mm, the height is 62.5 mm, and the length is 61.5 mm.
Is this terminal block suitable for harsh environments?
The insulation material is Thermoplastic with an inflammable class of UL94 V0, offering good resistance. However, for extremely harsh environments, additional protective measures might be necessary.
Troubleshooting
Conductor not securely held by spring clamp.
Ensure the conductor is stripped to the correct length and inserted fully into the terminal. Verify the conductor type and cross-section are within the specified range. If using ferrules, ensure they are properly crimped.
Fuse blows repeatedly.
Check the connected circuit for a short circuit or an overcurrent condition exceeding the 6.3A rating. Ensure the correct fuse type (G-fuse 5x20mm) is installed.
Terminal block does not fit DIN rail.
Confirm you are using a standard 35 mm top hat DIN rail. Check if the mounting clip on the terminal block is damaged or obstructed.
Pros and Cons
Pros
- Easy conductor connection with spring clamp technology.
- Compact footprint saves valuable space in control panels.
- Versatile potential distribution options with dual function shafts.
- Integrated fuse holder simplifies circuit protection.
- Accommodates a wide range of conductor cross-sections.
Cons
- Requires specific 5x20mm G-fuses.
- Only one level for connections.
- Not designed for high-current applications (rated 6.3A).
Setup, Compatibility & Care
Setup:
- Mount the terminal block onto a standard 35 mm DIN rail.
- Strip the conductor ends according to the specified cross-section ranges.
- Insert the conductor directly into the spring clamp terminal. A simple push or pull action secures or releases the conductor.
- For fuse protection, open the swiveling fuse holder, insert a 5x20 mm G-fuse (rated 6.3A), and close the holder securely.
- Utilize the two function shafts for potential distribution by connecting busbars or jumper elements as needed.
Compatibility:
- Conductor Cross-Sections:
- Fine-strand without ferrule: 0.08 to 4 mm²
- Fine-strand with ferrule: 0.14 to 4 mm²
- Solid-core: 0.08 to 6 mm²
- Multi-wired: 0.08 to 4 mm²
- Fuse Type: Requires 5x20 mm G-fuse
- Mounting: Compatible with 35 mm top hat DIN rails.
- Voltage/Current: Rated for 500V and 6.3A.
Care:
- Keep the terminal block clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
- Periodically inspect connections for signs of wear or damage. Ensure conductors remain securely clamped.
