Power entry connectors include inlets, outlets, and modules designed to handle power. These are often thought of as “heavy duty” power connectors as some can handle extremely high amperage or voltage. Connector styles include various IEC and NEMA along with some specialized for different countries. Some feature a circuit breaker and/or switch and different ingress protection (IP) levels.
Connector Style: An indication of the type of connection being used. Typically meets a standard.
Connector Type: Indicates the style/format of the connectors used to connect this product.
Current Rating (Amps): Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Voltage Rating: Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Number of Positions: The total number of electrical conductors the device has.
Mounting Type: Indicates how a device is attached.
Termination: Selection of termination style used to connect the device to a system, such as quick connect, screws, or wire leads.
Features: These are different capabilities or properties of the device such as board lock, chemical resistant, or strain relief.
Panel Cutout Dimensions: Refers to the measurements or dimensions of the opening or cutout in the panel.
Panel Thickness: The thickness or range of thicknesses the device would need to be able to mount properly in a panel hole.
Material Flammability Rating: Ensures compliance with the relevant UL Flammability Rating.
