What material is the housing made of?
The housing is made of durable thermoplastic.
Are special tools required for installation?
Yes, appropriate screwdrivers are needed to tighten the screw clamp terminals securely.
Troubleshooting
Terminal block not making secure connection
Ensure the conductor is stripped to the correct length and fully inserted into the terminal. Tighten the screw clamp firmly using the appropriate tool. Verify the conductor size matches the terminal's specifications.
Overheating at terminals
Check that all screws are tightened to the manufacturer's recommended torque. Verify that the conductor size is within the specified range for the terminal. Ensure adequate ventilation around the block.
Difficulty mounting to DIN rail
Ensure you are using a standard 35mm DIN rail. Check that the mounting mechanism on the terminal block is clean and free of obstructions. Apply slight downward pressure while engaging the rail.
Pros and Cons
Pros
- High amperage rating (250A) for significant power handling.
- Flexible input and output terminal configurations support diverse wiring needs.
- Compact dimensions (96mm x 45mm x 50mm) facilitate space-saving installations.
- DIN rail mounting ensures quick and secure panel integration.
- Contact-safe design enhances user safety.
Cons
- Specific input and output wire size limitations require careful planning.
- Single-pole configuration limits use in multi-phase systems without additional components.
- Requires appropriate tools for secure screw clamp connections.
- Not designed for direct outdoor or harsh environmental exposure without proper enclosure.
Setup, Compatibility & Care
Setup:
- Ensure the power source is de-energized before installation.
- Mount the terminal block securely onto a standard DIN rail using its integrated mounting mechanism.
- Strip the ends of the input and output conductors according to the recommended lengths for the screw clamp terminals.
- Insert the conductors into the appropriate input (1x 35-120mm²) and output (2x 6-35mm²/5x 2.5-16mm²/4x 2.5mm²) terminals.
- Tighten the screw clamp terminals firmly with a suitable screwdriver to ensure a secure connection. Ensure all conductors are fully seated and clamped.
Compatibility:
- Compatible with standard 35mm DIN rail.
- Supports conductor cross-sections as specified: 1x 35-120mm² (input) and multiple outputs including 6-35mm², 2.5-16mm², and 2.5mm².
- Maximum current rating: 250A.
- Maximum voltage rating: 1 kV.
Care:
- Periodically inspect connections for tightness, especially after periods of high load or vibration.
- Keep the terminal block clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid harsh chemicals or solvents.
- Ensure proper ventilation around the terminal block within the enclosure to prevent excessive heat buildup.
