摘要： A solid-state circuit breaker module (17) for integration into a power converter, the circuit breaker module (17) having an outer housing (19), the outer housing (19) containing:
a. a semiconductor switch (7), which acts as a main overcurrent protection device;
b. an electromechanical protective relay (9), which acts as a fallback overcurrent protection device;
c. a fuse (35), which acts as an ultimate overcurrent protection device;
d. a current sensor for detecting an overcurrent;
e. a controller for tripping the semiconductor switch (7) and the protective relay (9) when the current sensor detects an overcurrent; and
f. a sealed gas chamber (29) filled with an arc-extinguishing gas, the gas chamber (29) containing the semiconductor switch (7), the protective relay (9), and the fuse (35).

摘要： Electric fuse (2) for an aircraft solid state power controller (22) comprising at least one electric conductor (4), which is connected between an electric input terminal (6a) and an electric output terminal (6b), and which is configured to blow when an electric current (I) flowing through the at least one electric conductor (4) exceeds a predefined threshold (Imax). The at least one electric conductor (4) is encapsulated in a potting (8) and at least one outer surface of the potting (8) is covered with a polymeric coating (10).
