Please find the complete data in the user's documentation. Our General Terms of Use for Downloads are valid (http://phoenixcontact.com/download) Electronic circuit breaker, signal contact: 1 N/C contact, nominal current: 10 A Product Features  Selective protection of all 24 V DC load circuits at switched-mode power supply units  A combination of active electronic current limitation in the event of short circuit and overload shutdown ensures that the circuit breaker can respond to overloads faster than the switched-mode power supply unit  The residual current is always limited to 1.3 - 1.8 times the nominal current   Key commercial data Packing unit 1 pc Weight per Piece (excluding packing) 72.466667 GRM Custom tariff number 85362010 Country of origin Germany Technical data General Installation instructions When mounted in rows without convection cooling, the nominal device current should only be led to a maximum of 80% due to the thermal effect during continuous operation (100% operating factor). Special precautionary measures must be taken in systems or machines, to prevent components from restarting (e.g., use of a safety PLC). Parallel connection of multiple circuit breakers is not permitted.
