摘要： A safety apparatus is a terminal shield having an indication circuit incorporated therein. The safety apparatus is usable with a circuit interrupter to overlie one or more terminals of the circuit interrupter that are connected with line and load conductors and to thereby form a circuit interrupter apparatus. The safety apparatus can be employed at the line side of a circuit interrupter, at the load side of a circuit interrupter, or at both sides of a circuit interrupter. The safety apparatus can be provided as part of a new circuit interrupter apparatus or can be provided to retrofit existing circuit interrupters. The indication circuit advantageously outputs from a top surface of the terminal shield one of a visual indication and an audible indication when one or more terminals of the circuit interrupter are electrified, thereby easily conveying to a technician the portions of the circuit interrupter that are electrified.

摘要： A circuit breaker is provided that may be plugged onto an electrical panel. The circuit breaker is preferably a low voltage circuit breaker in the range of 120-240 volts. The circuit breaker may have an electrical clip with a curved inner surface that contacts a curved outer surface of an electrical connector on the electrical panel. The circuit breaker may also have a protrusion that prevents the circuit breaker from being installed in electrical panels without an electrical connector for the electrical clip to engage.

摘要： A circuit breaker system includes a first circuit breaker and a second circuit breaker. The first circuit breaker has a first trip unit, a first control unit, and a first electrical sensor. The first control unit is configured to control the first trip unit. The second circuit breaker has a second trip unit, a second control unit, and a second electrical sensor. The second control unit is configured to control the second trip unit. The first control unit is in communication with the second control unit. The first control unit is configured to monitor the communication with the second control unit to determine whether there is an internal device failure in the second circuit breaker. The first control unit is configured to change the first control unit's standard tripping characteristics to emergency tripping characteristics based on detecting the internal device failure of the second circuit breaker.

摘要： The invention relates to a switching device, in particular for a voltage limiting device, which has a first fixed switching contact 14 which is electrically connected to a first device terminal 8, a second fixed switching contact 15 which is electrically connected to a second device terminal 9, and a movable switching contact 16. The invention also relates to a voltage limiting device which has such a switching device 5. The first and second fixed switching contacts 14, 15 of the switching device are arranged next to one another in such a way that their contact surfaces 14A, 15A point in the same direction. The movable switching contact 16 can be moved between a closed position in which the first and second fixed switching contacts 14, 15 are electrically connected to one another, and an open position in which the first and second fixed switching contacts 14, 15 are separated from one another. The first and second fixed switching contacts 14, 15 and the movable switching contact 16 form an arrangement of electrical conductors which are arranged substantially parallel to one another. At least one of the fixed switching contacts 14, 15 has an elongated contact surface which extends in the direction A of current flow. Electrodynamic forces act on the fixed conductors 14, 15 and the movable conductor 16, which are directed in such a way that the conductors attract each other, i.e., the switching contacts tend to close.

摘要： A safety device for emergency shut-down of an electric instantaneous water heater. The safety device includes a contact and a counter contact, which are set up to conduct the current for supplying the instantaneous water heater in a contacted state and to interrupt the power supply of the instantaneous water heater in an open state. Further, the safety device includes a mounting device for mounting the counter contact on a tie rod, wherein the tie rod is set up to release the mounting device and the counter contact 4 from the contact to interrupt a power supply of the instantaneous water heater. The contact of the safety device is implemented as a contact rivet which is integrated directly into a circuit board.
