( Brand: Westinghouse ), ( Manufacturer Part Number: AN11P )
The Westinghouse AN11P Thermal Overload Relay is a versatile and essential electrical safety component designed to protect motors and other electrical equipment from overheating and potential damage. This 600VAC relay is manufactured by Westinghouse Electric, a renowned name in the electrical industry known for its high-quality and reliable products.
The AN11P Thermal Overload Relay is designed with a thermal element that responds to the temperature increase in the coil caused by the current flowing through it. Once the temperature exceeds a certain threshold, the relay trips, disconnecting the power supply to the motor or other equipment. This mechanism ensures the safety and longevity of the electrical system by preventing the motor from overheating and potentially causing a fire or other damage.
This relay is suitable for use in a wide range of applications, including industrial machinery, HVAC systems, pumps, compressors, and other electrical equipment. It is a single-phase thermal overload relay, with a trip setting range of 5 to 30 amps and a maximum continuous current rating of 600VAC. The AN11P is designed with a rugged construction, making it suitable for harsh environments and heavy-duty applications.
The Westinghouse AN11P Thermal Overload Relay is easy to install and operate. It features a clear, easy-to-read dial that indicates the trip setting, making it simple to adjust the relay to the appropriate setting for the specific application. The relay also comes with a mounting bracket, making it easy to mount and secure in place.
The AN11P Thermal Overload Relay is a reliable and efficient solution for electrical safety and protection. Its ability to trip when the motor or equipment overheats helps prevent damage and downtime, ensuring the continuity of operations and reducing maintenance costs. With its rugged construction, wide range of applications, and easy installation, the Westinghouse AN11P Thermal Overload Relay is an excellent choice for any industrial or commercial electrical system.
