Review SQUARE D Square8501-a0-22 4-pole Relay Nema Size Class 110-115vac Coil

The Square D 8501-A0-22 4-Pole Relay is a versatile and reliable electrical component designed for various applications requiring form C changeover contacts. This Nema 110-115VAC coil-operated relay adheres to the highest industry standards, ensuring dependable performance and long service life.

The 8501-A0-22 model boasts a 4-pole design, which offers two sets of normally open (NO) contacts and two sets of normally closed (NC) contacts. Each contact can handle up to 10 amperes of current at 600 volts maximum, making it suitable for handling heavy loads. The contacts are rated for a total of 25 amperes at 30 degrees Celsius contact temperature rise.

The coil of this relay has a voltage requirement of 110-115VAC and can handle a current of up to 0.5 amperes. The coil is designed to be efficient, ensuring quick response times and minimizing power consumption. The relay is also equipped with a built-in overload protection feature, which automatically disconnects the coil if the current exceeds the specified limit, thus preventing damage to the component.

The Square D 8501-A0-22 4-Pole Relay is housed in a robust and durable die-cast aluminum enclosure. The enclosure is designed to protect the internal components from external environmental factors, such as dust, moisture, and other contaminants. The relay is also UL listed, ensuring compliance with the highest safety standards.

The relay features a form C changeover contact configuration, which allows for two sets of contacts to change state simultaneously. This feature is particularly useful in applications where multiple loads need to be controlled by a single signal. The contacts are also designed to provide low contact resistance, ensuring minimal power loss and maximizing efficiency.

In summary, the Square D 8501-A0-22 4-Pole Relay is a high-performance, reliable, and versatile electrical component that offers form C changeover contacts, a robust die-cast aluminum enclosure, and a coil that is efficient and easy to operate. Its 4-pole design, 110-115VAC coil, and ability to handle heavy loads make it an ideal choice for various applications requiring reliable and efficient electrical switching.
