Our General Terms of Use for Downloads are valid (http://download.phoenixcontact.com) Electronic circuit breaker, signal contact: 1 N/C contact, nominal current: 2 A Why buy this product 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 Minimum order quantity 6 Catalog page Page 202 (TT-2011) GTIN Custom tariff number 85362010 Country of origin GERMANY Technical data General Color black Insulating material PA-F Inflammability class according to UL 94 V0 Dimensions Width 12.5 mm Length 80 mm Height NS 35/7.5 83 mm Height NS 35/15 90.5 mm Technical data Fuse Electronic Fuse type Automatic device Nominal current IN 2A Nominal voltage UN 24 V DC (up to max. 32 V) Switching capacity ICN (Active current limitation) 01.06.2012 Page 1 / 6 https://www.phoenixcontact.com/us/produkte/0903033 Circuit breakers -
