1. Structure: Employs screw clamping technology, using a screwdriver to tighten screws to secure the wires.

2. Material: The outer shell is made of flame-retardant PA66 material, and the clamping components are made of highly conductive copper alloy, possessing excellent mechanical strength and electrical properties.

3. Marking: Features a transparent plastic label and universal test holes for easy circuit identification and live measurement.

1. Mounting Method: Direct soldering or crimping to the PCB board.

2. Connection Technology: Mostly screw connections or spring clamps (such as WAGO’s CAGE CLAMP® technology), the latter enabling tool-free, quick wiring.

3. Pitch: Standard pin pitches (e.g., 3.5mm, 5.0mm, 7.5mm, 10.0mm, etc.) perfectly match the PCB design.

1.High Current Carrying Capacity: Utilizes large-size copper alloy conductors and optimized design, resulting in low contact resistance and excellent heat dissipation.

2.Robust Construction: Metal or high-strength engineering plastic housing, shock and impact resistant.

3.Connection Methods: Typically employs screw connections or hydraulic clamping to ensure excellent clamping force for large cross-section conductors (up to 185mm² or even larger).

1.Quick Connection: Simply use a screwdriver or your finger to operate the lever to open the spring clip, insert the wire, and release to complete the connection; no screws are required.

2.Vibration Resistance: The constant force design of the spring effectively compensates for wire cold creep, providing vibration resistance far exceeding that of screw connections.

3.Wide Wire Diameter Compatibility: One terminal is compatible with multiple wire diameters within a range, reducing the variety of items in your inventory.

1.Multi-layer structure: Typically designed with two or more layers, each with independent wiring holes, but all layers are electrically connected internally.

2.Flexible wiring: Allows wires from different directions and with different wire diameters (such as power inputs and multiple outputs) to converge at the same terminal, achieving a “one-in, multiple-out” star topology.

3.Neat and aesthetically pleasing: Significantly reduces the messy jumpers used for equipotential bonding within the control cabinet, making wiring orderly and facilitating later wiring traces and maintenance.

4.Optional accessories: Usually comes with pre-fabricated metal jumper clips, which can easily bridge multiple TD terminals laterally, quickly achieving potential distribution for multiple circuits.

1.Compact Design: Narrower than traditional UK terminals, allowing for more terminals to be installed within the same rail length, significantly saving control cabinet space.

2.Connection Technology: Employs a direct-insertion spring connection; connections are completed simply by pressing the wire directly into the opening with a screwdriver, resulting in high efficiency.

3.High Density: Small pin pitch and compact structure, yet uncompromising performance.

1.Integrated Switch: A clearly colored (usually red) operating handle allows for easy connection or disconnection of the circuit, with a clear “ON/OFF” indication.

2.Safety Isolation: Provides a visible disconnect point for easy equipment maintenance, debugging, and emergency power-off, enhancing safety.

3.Testing Function: Many models also integrate test ports for convenient measurement without disconnecting the leads.

1.Highly Identifiable: Typically uses a yellow-green plastic casing (compliant with international grounding wire color standards), providing high visibility, preventing misconnection, and ensuring safety.

2.Metal Connecting Plate: All clamping points inside the terminals are electrically connected via a highly conductive metal connecting plate (usually a copper busbar), ensuring all grounding points are at the same potential.

3.Low Impedance Path: Provides a reliable, low-impedance current path for the grounding loop, ensuring rapid operation of the protection device in the event of a fault.

4.Installation Method: Similar to the UK series, it uses a TH35 top-cap DIN rail for high compatibility.

1. Built-in Short-Circuit Bridge: This is the core function of the IN terminal. It features a movable short-circuit piece (short-circuit bridge) and test sockets.

2. Normal Operating State: When the short-circuit piece is open, current flows through the terminal, supplying the downstream measuring instruments (such as electricity meters and ammeters).

3. Maintenance and Testing State: When maintenance or replacement of downstream instruments is required, the short-circuit piece can be inserted to safely short-circuit the secondary output of the current transformer before disconnecting the downstream wiring, thus ensuring absolute operational safety.

4. Provides clear test points, facilitating calibration and diagnostics by connecting measuring equipment without disconnecting the circuit.
