A smart fuse

摘要

A smart fuse (100; 200; 300) adapted to be plugged on a DIN rail in an electricity cabinet with a 230 Volts incoming phase (151, 152; 251, 252; 351, 352) and existing cabling for one or more outgoing circuit (161, 162; 261, 262; 361, 362) towards one or more electrical device, is designed to occupy in that electricity cabinet an entire width substantially equal to 3,50 cm or 2 TE. The smart fuse (100; 200; 300) comprises a circuit breaking element (101; 201; 301) housed in a first housing (110; 210; 310) and one or more intelligent function (102; 202; 302) series connected with the circuit breaker (101; 201; 301) and housed in a second L-shaped housing (120; 220; 320). The smart fuse (100; 200; 300) further has two ingoing terminals (131, 132; 231; 232; 331, 332) for connectivity to the 230 Volts incoming phase (151, 152; 251, 252; 351, 352) and two outgoing terminals (141, 142; 241, 242; 341, 342) for connectivity to cabling for an outgoing circuit (161, 162; 261, 262; 361, 362). The distance between the two outgoing terminals (141, 142; 241, 242; 341, 342) is between 0,5 TE and 1,5 TE allowing the existing cabling to be reused.
