Structural Design Innovation
Anti-Misplugging Design
Equipped with anti-misplugging key positions and three types of coding positioning bosses, these terminal blocks eliminate the risk of incorrect circuit connections. This feature is crucial for maintaining the integrity and safety of electrical systems.
01
Torque-Compensated Screws
The torque-compensated screws automatically calibrate the tightening torque (0.5-2N·m), preventing issues caused by over-tightening or under-tightening. This ensures consistent and reliable electrical contact, reducing the likelihood of loose connections.
02
Wide Wire Compatibility
Capable of accommodating wires ranging from 0.5mm² to 50mm² (AWG22-AWG4), these terminal blocks cover 95% of industrial wiring requirements. They can handle both solid and stranded wires, providing versatility in various applications.
03
Precision Alignment for Dense Installations
The side-by-side installation clips feature a precision tolerance of ±0.1mm, enabling high-density installation in electrical cabinets. This design maximizes space utilization and simplifies wiring management.
04
Electrical Performance Parameters
Rated Voltage and Current
With a rated voltage of 600V AC/1000V DC (compliant with IEC 60947-7-1) and a current range of 10A-200A (varying by model), these terminal blocks can handle diverse electrical loads. The temperature rise is controlled within ≤60K, ensuring stable operation even under continuous high-current conditions.
High Voltage Resistance
Passing a withstand voltage test of 2500V AC for 1 minute with a leakage current of <5mA, these blocks offer excellent insulation and protection against electrical breakdowns. This high voltage resistance is essential for maintaining safety in electrical systems.
Optimal Creepage Distance
Maintaining a creepage distance of ≥8mm (pollution degree 3, insulation material group IIIa), these terminal blocks meet strict safety standards. This distance helps prevent electrical leakage and ensures reliable insulation in various environmental conditions.
Low Electrical Loss
Engineered to minimize electrical losses, these blocks contribute to the overall efficiency of electrical systems, reducing energy consumption and operational costs.
Application Scenario Solutions
Industrial Automation
In industrial automation systems, Rail Terminal Blocks are widely used for internal signal and power wiring in control cabinets, such as connecting PLC modules and servo drives. Their modular design reduces wiring time by 60%, while the anti-vibration structure ensures stable long-term operation, even in high-vibration environments.
Power Equipment
For power distribution systems, Terminal Screw Connectors are used for busbar transfer in switchgear and low-voltage connections of transformers. Custom solutions, such as large-current terminals (100A+) with heat dissipation fins, can reduce temperature rise by 15%, enhancing the reliability of power equipment.
New Energy Sector
In the new energy field, these terminal blocks play a crucial role in the internal wiring of photovoltaic inverters and the series/parallel connection of energy storage battery packs. The weather-resistant housing can withstand extreme temperatures from -40℃ to 85℃, and all products comply with RoHS 2.0 standards, ensuring environmental friendliness.
Lighting Systems
In lighting applications, Ground Terminal Blocks are essential for safety grounding in LED streetlight control boxes and landscape lighting distribution boxes. The easy-to-use, non-stripping terminal design improves on-site installation efficiency by 30%, making lighting projects more time-effective.
