Abstract: An electric power distribution panel is provided. The electric power distribution panel includes a first input bus, a second input bus, a plurality of brackets and a plurality of circuit breaker modules. The first and second input buses are coupled to a first power source and a second power source respectively. The plurality of brackets is electrically connected to the first and second input buses. The plurality of circuit breaker modules are assembled to the plurality of brackets respectively. Each of the plurality of circuit breaker modules includes a circuit breaker and an adapter detachably assembled to the circuit breaker. In each of the plurality of circuit breaker modules, the circuit breaker is electrically connected to the first input bus when the adapter is removed from the circuit breaker, and the circuit breaker is electrically connected to the second input bus when the adapter is assembled to the circuit breaker.

Abstract: A power system is provided, including a power module, a plurality of first electric apparatus safety devices, and a plurality of second electric apparatus safety devices. The first electric apparatus safety devices and second electric apparatus safety devices are arranged along a first direction of the power system. The first electric apparatus safety devices, the second electric apparatus safety devices, and the power module are stacked along a second direction of the power system, wherein the first direction is perpendicular to the second direction.

Abstract: A case for receiving at least one electronic device is provided, including a housing, a hinge, a locking member, and a cover. The housing has an accommodating space and an opening communicated with the accommodating space. The hinge is slidably connected to the housing. The cover has an upper side, a lower side, and an outer surface. The lower side is pivotally connected to the hinge. When the locking member affixes the upper side to the housing and the hinge is in a first position relative to the housing, the cover is disposed between an environment space and the accommodating space, and the outer surface faces the environment space. When the locking member is released and the hinge moves to a second position relative to the housing, the cover leaves the position between the environment space and the accommodating space, and the outer surface faces the environment space.

Abstract: A surge protection apparatus includes a chassis, a surge circuit breaker, and a surge protection module. The chassis has an accommodating space and an opening, and the opening is communicated with the accommodating space. The surge circuit breaker is disposed in the accommodating space. The surge protection module is configured to be electrically connected to a second connector in the chassis, and the second connector is electrically connected to the surge circuit breaker. The surge protection module extends in a first axis, and the surge protection module is plugged in or pulled out of the chassis through the opening along the first axis. The surge protection module includes a first connector detachably connected to the second connector.
