Barrier Strip Terminal Block 20A 12mm 380V

barrier strip terminal block rated at 20A with a pitch of 12mm and a voltage rating of 380V is commonly used in industrial, commercial, and residential electrical applications. This type of terminal block is designed to connect multiple wires in a safe and organized manner, typically used for power distribution, control circuits, and equipment wiring.

Key Features

1. 20A Current Rating: This terminal block can handle a maximum current of 20 amps, making it suitable for moderate to heavy electrical loads.
2. 12mm Pitch: The pitch refers to the distance between the centers of adjacent terminals. A 12mm pitch allows for sufficient spacing for wire connections while still being compact enough for many applications.
3. 380V Voltage Rating: The terminal block can withstand up to 380 volts, making it appropriate for various high-voltage applications, including industrial motor controls and power distribution.
4. Barrier Design: The barrier strip terminal block features separate sections (or barriers) between terminals, which helps prevent accidental short circuits and improves safety during installation and operation.
5. Material Construction: Typically made from insulated materials such as nylon or polyamide, these terminal blocks may have conductive parts made from tinned copper or brass for good electrical conductivity.

Configuration

A barrier strip terminal block typically has multiple terminals, often in a linear configuration. For instance, a 10-way terminal block with a 12mm pitch would look like this:

Copy      +-----------------------------------+
      | Terminal 1  |  Terminal 2  | ... |
      +-----------------------------------+
      |   | |   | |   | |   | |   | |   |
      +-----------------------------------+

• Each terminal has a separate mounting point, allowing wires to be connected without interference from adjacent connections.

Applications

Barrier strip terminal blocks are widely used in:

• Electrical panels: For organizing connections in control panels and switchboards.
• Industrial Equipment: In machinery where multiple connections are required.
• Motors: For connecting power and control circuits to motors.
• Power Distribution: In facilities requiring organized wiring for power distribution to various circuits.
• Instrumentation: For connecting sensors and control devices.

Considerations

1. Wire Size: Ensure that the terminal block can accommodate the gauge of wire used in your application. The size of the wire should match the terminal specifications to ensure proper current handling.
2. Fork or Ring Terminals: Some barrier strip terminal blocks are designed to use fork or ring terminals instead of solid wire connections. Check compatibility.
3. Mounting Style: Consider how the terminal block will be mounted (e.g., on a DIN rail, directly to a panel, etc.) and ensure it fits your design specifications.
4. Environmental Conditions: Assess factors such as temperature, humidity, and exposure to chemicals in the installation environment, and choose a terminal block that is suitable for those conditions.
5. Local Codes and Standards: Ensure compliance with local electrical codes and standards when selecting and installing terminal blocks.
