Expand your circuit board's power distribution capabilities with the 4P 20A 300V Terminal Block. This heavy-duty 4-pin barrier connector is precision-engineered for PCB-mount applications that require consistent, high-current performance in a rugged package. Rated for 20A and 300V, it provides four independent, secure termination points for complex power inputs and motor control signals.
Multi-Circuit 4-Pin Layout: Provides four individual terminal positions for organized wiring of multi-phase power or multiple signal lines.
Robust 20A Capacity: Designed to safely manage continuous current loads up to 20A, making it ideal for high-power industrial electronics.
Standard 300V Insulation: Offers a high dielectric strength of 300V, ensuring safe operation across a wide range of AC and DC applications.
Through-Hole PCB Mounting: Equipped with four sturdy metal pins for direct soldering into circuit boards, offering excellent mechanical stability and low contact resistance.
Heavy-Duty Screw Terminals: Features high-torque screws with integrated pressure plates to ensure a vibration-proof grip on both solid and stranded wires.
The 4-Pin 20A Terminal Block is the professional choice for:
Industrial Control Systems: Managing power and signals for multi-stage relay boards and PLCs.
Power Inverters & Converters: Providing a rugged interface for high-current input and output stages.
HVAC and Motor Control: Connecting multi-wire motor leads or fan control circuits to a main PCB.
Automotive Electronics: Serving as a durable power distribution hub in custom vehicle electrical systems.
Pin Count: 4 Position (4P).
Current Rating: 20A.
Voltage Rating: 300V.
Can I use this for 3-phase power applications?
Yes. With four pins, this block can comfortably accommodate a 3-phase connection plus a ground or neutral line, provided the voltage is within the 300V rating.
What is the best way to ensure the wires don't vibrate loose?
For the most secure and professional fit, use insulated crimp fork terminals (U-type). These lock under the screw heads and work with the pressure plates to provide a vibration-resistant connection.
Are the PCB pins long enough for thick or double-sided boards?
The pins are designed with a standard length for through-hole soldering, providing ample reach for most standard and multi-layer PCBs while maintaining high mechanical strength.
