Schneider TSXCDP203
The TSXCDP203 is a modular power distribution terminal block from Schneider Electric’s Compact NS series, specifically designed for industrial distribution cabinets, equipment rooms, and automation systems. Featuring a compact structure, it supports quick wiring and high-reliability connections, making it suitable for 3-phase 4-wire (3P+N) or 3-phase 5-wire (3P+N+PE) power distribution solutions.
Key Technical Specifications
- Model: TSXCDP203
- Length: 2 meters
- Conductor Cross-Sectional Area: 0.324 mm² (equivalent to AWG 22)
- Rated Current: 80 A (at 65 °C ambient temperature)
- Operating Voltage: AC 400 V (50/60 Hz)
- Pole Configuration: 3P (3P+N or 3P+N+PE optional)
- Connection Method: HE10 terminals with screw crimping for fast assembly
- Material: Flame-retardant copper busbar, compliant with international safety standards such as IEC 60364 and EN 60204
Product Features
- Modular & Customizable: Standard 2m length can be field-cut to required dimensions, offering flexible adaptation to different distribution cabinet sizes.
- High Current Capacity: 80A rated current meets the demands of medium-power industrial loads.
- Reliable Connection: HE10 terminals provide secure crimping, ensuring anti-loosening and vibration resistance.
- Compact Design: Space-saving structure ideal for high-density distribution cabinet layouts.
- International Standard Compliance: Adheres to IEC, EN, and other safety/electrical regulations for compliant installations.
- Multi-Pole Options: Supports 3P, 3P+N, and 3P+N+PE wiring configurations to meet diverse system requirements.
Structure & Composition
- Copper Busbar Body: Flame-retardant copper material delivering the main current path.
- Terminal Blocks (HE10): Distributed on both sides of the busbar, corresponding to phase lines, neutral lines, and protective grounding respectively.
- Support Frame: Metal bracket for busbar fixation, facilitating installation in distribution cabinets.
- Identification Labels: Clear phase sequence, neutral, and grounding markings on each terminal for simplified on-site wiring.
Typical Application Areas
- Industrial automation distribution cabinets
- Equipment room power distribution systems
- Energy management and power distribution stations
- Process control systems (e.g., chemical, metallurgical industries)
- Transportation facilities (e.g., subway, airport)
Installation & Maintenance Guidelines
Pre-Installation Checks
Verify distribution cabinet dimensions, required current, and voltage ratings to ensure model compatibility.
Cutting & Positioning
Cut the busbar to the actual required length, fix it with the support frame, and maintain a horizontal orientation.
Terminal Crimping
Use specialized crimping tools to press wires into HE10 terminals, ensuring firm and secure connections.
Wiring Identification
Strictly follow phase sequence, neutral, and grounding labels during wiring to prevent misconnections.
Insulation Testing
After installation, use an insulation resistance tester to check insulation values between phases and ground, ensuring compliance with safety requirements.
Regular Maintenance
Inspect terminal crimping conditions every 6-12 months, remove dust and corrosion, and re-crimp or replace terminals if necessary.
