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/O contact, nominal current: 2 A ## Why buy this product 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 Selective protection of all 24 V DC load circuits at switched-mode power supply units The residual current is always limited to 1.3 - 1.8 times the nominal current ## Key Commercial Data |Packing unit|1 STK| |---|---| |Weight per Piece (excluding packing)|74.640 g| |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).
