Power entry connectors include inlets, outlets, and modules
designed to handle power. Some are designed to filter out unwanted frequency (EMI, RFI) from a circuit. 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. Accessories
are available for various functions such as, sealing, strain relief, and more.
