Fused electrical disconnect device for high current applications

A low voltage, high current fused electrical disconnect device comprising:

• a housing defining a cartridge receptacle and including electrically conductive, laterally spaced line and load interfaces within said receptacle;
• generally cylindrical, laterally spaced line and load terminals extending from said housing, said line terminal being electrically coupled to said line interface and said load terminal being electrically coupled to said load interface;
• a fuse holding cartridge removably insertable into said receptacle and releasably accommodating a load protection fuse, said fuse holding cartridge establishing an electrical current path between said line and load interfaces when said fuse holding cartridge accommodates a load protection fuse and said fuse holding cartridge is inserted into said receptacle, said fuse holding cartridge comprising a pair of resilient spring elements to engage said line and load interfaces thereby to retain said fuse holding cartridge in said cartridge receptacle;
• and
• an alarm signal circuit in electrical communication with said line and load terminals, said alarm signal circuit generating an alarm signal when said electrical current path is interrupted and said line and load terminals are electrically coupled to a power source and load respectively.

A fused electrical disconnect device comprising:

• a housing defining a cartridge receptacle and including a line interface and a load interface within said receptacle;
• a line terminal extending into said body and being in electrical communication with said line interface;
• a load terminal extending into said body and being in electrical communication with said load interface;
• a fuse holding cartridge removably insertable into said cartridge receptacle and releasably accommodating a load protection fuse, said fuse holding cartridge establishing an electrical current path between said line and load interfaces when said fuse holding cartridge accommodates a load protection fuse and is inserted into said cartridge receptacle, said fuse holding cartridge comprising a biased retaining mechanism to maintain said fuse holding cartridge in secure contact with said line and load interfaces;
• and
• an alarm signal circuit in electrical communication with said line and load terminals, said alarm signal circuit generating an alarm signal when said electrical current path is interrupted and said line and load terminals are electrically coupled to a power source and load respectively.

A low voltage, high current fused electrical disconnect device comprising:

• a housing having an upper surface and defining a cartridge receptacle and including electrically conductive, laterally spaced line and load interfaces within said receptacle;
• laterally spaced line and load terminals extending from said housing, said line terminal being electrically coupled to said line interface and said load terminal being electrically coupled to said load interface;
• a fuse holding cartridge removably insertable into said receptacle and releasably accommodating a load protection fuse, said fuse holding cartridge being flush with said upper surface and establishing an electrical current path between said line and load interfaces when said fuse holding cartridge accommodates a load protection fuse and is inserted into said receptacle, said fuse holding cartridge including bias clips to engage said line and load interfaces, thereby to retain said fuse holding cartridge in said cartridge receptacle;
• and
• an alarm signal circuit in electrical communication with said line and load terminals, said alarm signal circuit generating an alarm signal when said electrical current path is interrupted and said line and load terminals are electrically coupled to a power source and load respectively.
