The CAMTEC ESB101 series are cost-effective second-generation inrush current limiters. The limiters are designed for 115/230Vac 16A networks. The permissible mains frequency is 16⅓Hz – 440Hz. The ESB101 limiters are connected between the main switch/contactor and the load. The ESB series is approved for use with inductive and capacitive loads. At the moment of switching on, the inrush current caused by the connected loads is limited for a defined period of time, regardless of the actual starting current. The limitation is always strictly enforced. After the time has elapsed, the current limitation in the ESB101 is bypassed. The load is now directly connected to the mains. The network can be loaded with short-term peak currents as usual (e.g., motors, pumps). If a power failure lasts longer than the defined time, the ESB101 detects this. When the power returns, the inrush current limitation is applied again. The device is internally temperature monitored. In case of a fault, the device shuts down, effectively preventing permanent overheating or fire.
