Contactors (Electromechanical) are electrical switches used to control large amounts of power using a small amount of controlling power. The PBC-025A1B7 is a contactor that meets 2-pole, 50-amp rated operational performance criteria, making it suitable for a wide variety of applications. This contactor uses a coil to attract the contact arm and hold it in place to complete the electrical circuit.
PBC-025A1B7 Applications
The PBC-025A1B7 contactor is suitable for many applications, as it is UL and CSA listed, meeting all necessary safety criteria and certifications. It is rated for 2 poles and 50-amp operation, making it ideal for motor applications, lighting systems, and other various industrial applications. The contactor is also sufficient for use in areas with high moisture levels, making it suitable for outdoor purposes.
PBC-025A1B7 Working Principle
The contactor’s working principle entails a control coil to magnetically attract the contact arm in order to complete the circuit. When power is sent to the coil, it magnetically attracts the contact arm, causing it to close the circuit and allow the current to flow.
The contactor also contains an auxiliary switch that can be used in tandem with the contactor itself. This auxiliary switch is mechanically actuated and requires minimum power, meaning that its performance will not be affected with a change in voltage.
Conclusion
The PBC-025A1B7 contactor is a versatile piece of equipment suitable for use in many applications. Its 2-pole, 50-amp rated operation makes it well-suited for motor applications, lighting systems, and other industrial applications. The working principle involves a control coil magnetically attracting the contact arm to complete the circuit, and it also contains an auxiliary switch which can be used in tandem with the contactor itself.
