Power entry connectors, referred to as PECs, are common components used in power and signal connections to electrical equipment. PECs are commonly used in industrial and commercial settings as well as in many residential structures.

Inlets, outlets, and modules constitute the main types of PECs. Inlets are used to connect an exterior power source to an internal electrical system, and outlets are used to split an exterior power source and provide power to multiple internal systems. Modules are used to interconnect power and signal cables and to provide EMC/EMI protection systems. PECs can be found in virtually every electrical system, ranging from small consumer devices to heavy industrial machines.

The 77W-00/01 power entry connector is a special type of PEC that is designed to meet UL and CSA requirements. This connector is a three-pole inlet with a universal locking ear. The connector is rated for 277 volts AC and 10 amps (maximum current rating). The UL and CSA requirements stipulate the connector\'s locking mechanism must have optimal strain relief, the contacts must be able to provide good electrical connection and endure significant electrical loads, and the connector must be able to withstand temperatures up to 125 degrees Celsius.

The 77W-00/01 consists of a connector body, which serves as the housing for the contacts, and the retention clip, which ensures the contacts remain securely in place. The contacts are made of brass and are plated with nickel for improved conductivity and increased corrosion resistance. The contacts are designed to fit a variety of wire diameters and styles, meaning they can be used in virtually any type of electrical system.

The 77W-00/01 connector is designed to be mounted directly onto a cabinet panel or enclosure with a suitable hole drilled through it. Once the connector is mounted to the panel, a power cord can be plugged into it. The retention clip then locks securely into place to ensure no accidental disconnection or cord pulling. The combination of the connector body and the retention clip allows the connector to provide a secure and reliable electrical connection.

The working principle of the 77W-00/01 is relatively straightforward. When a power cord is plugged into the connector, the contacts inside the connector body make contact with the power cord and establish a low-impedance electrical connection. The retention clip then secures the cord in place and ensures the connector remains securely attached to the panel.

The 77W-00/01 power entry connector is a robust, reliable, and cost-effective solution for power and signal connections to electrical and electronic equipment. Its robust construction and reliable contacts make it well-suited for a range of applications, from residential to industrial settings. Furthermore, its universal locking ear allows it to be used in a variety of mounting styles and configurations.
