Key Terminology & Reasoning:
1.SUT Series High-voltage Terminal Blocks
The product design complies with standards GB/T 14048.1 and GB/T 14048.7 (equivalent to IEC 60947-1 and IEC 60947-7-1). The rated voltage is designed for 1000V.
2.Connection Method
Terminals feature screw clamping for wire connection. The center bridge component utilizes a plug-in connection design and is compatible with the ST2/ST3 series spring clamp terminals.
1. Core Features & Technical Advancements
●Elevated Voltage Rating: The new SUT series supports 1000V rated voltage, significantly expanding its applicability in high-voltage environments such as rail transit, heavy machinery, and renewable energy systems.
●Screw-Terminal Design: Utilizing robust screw-clamping technology, the terminals ensure secure connections for wire sizes ranging from 2.5 mm² to 10 mm², suitable for both low- and high-current scenarios. The design minimizes contact resistance and enhances long-term reliability.
●Versatile Models:
○General-Purpose Terminals: Includes models SUT-2.5, SUT-4, SUT-6, and SUT-10, catering to diverse wiring requirements.
○Test Terminal (SUT-6S): Features a dedicated test port for safe voltage measurement and circuit diagnostics without disconnecting wires, ideal for maintenance and troubleshooting.
2. Compatibility
