Camtec 3041081001 Inrush current control

The CAMTEC ESB101 series consists of cost-effective second-generation inrush current limiters. These limiters are designed for 115/230Vac 16A networks. The permissible network frequency ranges from 16⅓Hz to 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, regardless of how high the actual starting current is. The limitation is always strictly enforced. After the time has elapsed, the current limitation in the ESB101 is bypassed, and the load is now directly connected to the network. The network can then be subjected to 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 monitored for temperature internally. In case of a fault, the device shuts down to effectively prevent permanent overheating or fire.
