Electronic circuit protector ESX10-T-DC48V Description The model ESX10-TC-DC48V extends our product group of electronic overcurrent protection devices to include DC 48 V applications. At a width of only 12.5 mm it provides selective protection for all DC 24 V, DC 36 V and DC 48 V load circuits. The robust design ensures unrivalled stability for selective protection of more loads at one DC power supply. The ESX10-TC-101-DC48V electronic circuit protector provides superior performance and functional reliability, especially for the protection of power trains such as DC motors, multiphase motors, servomotors and their control technology. ESX10-T helps to save time and costs. The track-mountable circuit protectors standard version provides one channel in the current ESX10-T DC 48 V ratings 1 A through 16 A. By means of busbars, the modular device allows construction of multi-channelled solutions and configuration of single or group signalling. The sophisticated mechanical design of the component also enables a minus load return directly to the module. This function enables hardware planners to realise a sub-distribution directly on the ESX10-T electronic circuit protector.
