Review ALLEN BRADLEY 700-p400a1/700-pb40 Ser Contactor Used Free Shipping

The Allen-Bradley 700-P400A1 and 700-PB40 contactor is a versatile and reliable solution for controlling electrical loads up to 600 Volts and 300 Amperes. This contactor is part of Rockwell Automation's Allen-Bradley PowerFlex Contactors product line, which is known for its rugged construction and advanced features.

The 700-P400A1 is the coil contactor, which consists of a set of normally open (NO) contact points that are controlled by the 700-PB40, the auxiliary contractor. The 700-PB40 is a pilot-operated, normally closed (NC) contractor that is used to energize the coil of the 700-P400A1. When the 700-PB40 receives a signal, it closes its contacts, allowing current to flow through the coil and causing the contact points in the 700-P400A1 to close, thus completing the circuit to the load.

The 700-P400A1 and 700-PB40 are designed with a number of features to ensure safe and efficient operation. They are rated for a maximum contact capacity of 125 Amperes per contact, and they have a current interrupting rating of 20,000 Amperes at 600 Volts for one second. This means that they can safely interrupt large currents in the event of a short circuit.

The contacts in the 700-P400A1 are made of silver alloy, which provides excellent conductivity and long-lasting performance. The contactor also has a built-in thermal overload relay, which can be used to protect the contactor and the load from overcurrent conditions. The contactor's contacts are designed to make and break quickly and smoothly, reducing the risk of arcing and contact welding.

The 700-P400A1 and 700-PB40 are also designed for easy installation and integration into control systems. They have a compact size and a modular design, which allows them to be used in a variety of applications. The contactor also has a number of optional accessories, such as current limiting resistors and position indicators, which can be added to customize the contactor for specific applications.

Overall, the Allen-Bradley 700-P400A1 and 700-PB40 contactor is a high-performance, versatile, and reliable solution for controlling electrical loads. Its rugged construction, advanced features, and easy installation make it an excellent choice for a wide range of applications in industries such as manufacturing, power generation, and oil and gas.
