Ensure secure and reliable power connections with our 25A 300V Barrier Terminal Block series. Designed for high-performance electrical distribution, these blocks are engineered to handle continuous loads up to 25A and voltages up to 300V, making them ideal for industrial power supplies, motor controllers, and heavy-duty PCB applications.
Versatile Pin Configurations: Available in a full range from 2-pin to 10-pin models to suit various circuit complexities.
Rugged Power Handling: Supports high-current demands up to 25A at 300V, ensuring stable performance under significant electrical stress.
PCB Mount Design: Equipped with sturdy metal pins for direct soldering into circuit boards, providing a permanent and vibration-resistant connection.
Integrated Safety Cover: Features a transparent, tinted protective shield that guards against dust and accidental contact while allowing for easy visual inspection.
Clear Terminal Marking: Each position is clearly numbered on the block face (e.g., 1, 2, 3) to prevent wiring errors during installation and maintenance.
These Barrier Terminal Blocks are a trusted choice for:
Industrial Power Supplies: Distributing high-current DC or AC power within control enclosures.
Motor Drive Units: Providing a secure termination point for heavy-gauge motor lead wires.
HVAC Control Boards: Managing power for fans, heaters, and compressor relays.
Renewable Energy Systems: Connecting battery banks and solar inverter inputs to custom PCBs.
Current Rating: 25A.
Voltage Rating: 300V.
Mounting Style: PCB Through-Hole.
Is the 4-pin model also 25A?
While most of this series is rated for 25A, some specific 4C (4-pin) variations may be rated at 10A. Always verify the specific marking on the block if your application requires the full 25A.
What wire size can these terminals hold?
The screw-down plates are designed to securely clamp a wide range of wire gauges, typically supporting 12 AWG to 22 AWG. For the most reliable high-current connection, we recommend using insulated crimp fork terminals.
Are the PCB pins strong enough for the weight of heavy wires?
Yes. These blocks are designed with heavy-duty metal pins meant to be soldered through the PCB. However, for very thick cables, it is best practice to provide external strain relief for the wires so they do not pull directly on the solder joints.
