KBC Networks ESULS4-M1-B Un-Managed Industrial Ethernet Switch

For demanding industrial surveillance and security networks, the KBC Networks ESULS4-M1-B Un-Managed Industrial Ethernet Switch delivers dependable PoE+ power and reliable connectivity at the network edge. This compact industrial Ethernet switch provides four 10/100 RJ45 ports with IEEE 802.3af/at support—each port delivering up to 30W—and a total PoE budget of 120W, so IP cameras, wireless APs and access control devices stay powered without separate injectors. An integrated 100M SFP uplink offers fiber connectivity to central switches or NVRs for long-distance, interference-free links.

Built for harsh environments, the KBC ESULS4-M1-B features IP40 housing, Level 3 ESD protection and redundant DC input (48/57V) plus overload/reverse-polarity safeguards, making it ideal for transportation, pipeline, power and automation applications. The plug-and-play, unmanaged design and unique DIN-rail/wall mount make installation fast and maintenance-free, reducing total cost of ownership. Use this switch to simplify deployments in security, surveillance and remote monitoring systems—contact your supplier to specify the ESULS4-M1-B for your next project.
