1. Common Parameter Categories
1.Current Rating
●Examples: 10A, 20A, 30A, 50A, 100A, etc. (Must match load requirements with a 10%~20% margin).
2.Conductor Cross-Section
●Conductor Size Range: e.g., 0.5–6mm², 1–10mm², 4–25mm² (Verify compatibility with copper/aluminum wires).
3.Terminal Type
●Plug-and-Socket Design (e.g., Fork Terminal Plug & Socket)
●Screw Clamp Type (e.g., Screw Clamp Terminal)
●Double Fork Splitter Configuration (e.g., Double Fork Splitter Terminal)
4.Protection Rating
●IP Rating: e.g., IP20 (dry environments), IP67 (waterproof/dustproof).
5.Material and Certification
●Materials: Flame-retardant materials such as PA (Polyamide), PBT (Polybutylene Terephthalate).
●Certifications: UL/CUL, IEC 60947, CCC (China Compulsory Certification), etc.

3. Selection Guidelines
1.Current and Load Matching
●Ensure the rated current ≥ actual load current (with 10%~20% margin).
2.Conductor Compatibility
●Verify the conductor diameter fully falls within the terminal’s specified range.
3.Environmental Adaptability
●High-Temperature Environments: Choose heat-resistant materials (e.g., PA66).
●Vibration-Prone Applications: Prioritize screw-clamp or locking mechanisms.
4.Installation Method
●Surface-mount or recessed designs depend on enclosure compatibility (e.g., rail-mounted or embedded interfaces).
4. Notes
●Brand-Specific Naming: Models vary by manufacturer (e.g., Phoenix Contact’s FT Series, Weidmüller’s WAGO Series); consult product catalogs.
●Specialized Standards: For hazardous environments (explosive atmospheres) or rail transit, use certified models (e.g., ATEX explosion-proof certification).
If further details are needed (e.g., specific brand models or technical specs), provide additional context such as application environment, voltage, conductor type, or required certifications!
