摘要： A switch device may comprise a micro-relay disposed between a first terminal and a second terminal. The micro-relay may be configured to selectively electrically couple the first terminal to the second terminal. The switch device may further comprise a bypass circuit configured to selectively divert at least a portion of electrical current flowing from the first terminal to the micro-relay, and direct the diverted electrical current to the second terminal. The switch device may further comprise an energy harvesting circuit configured to (i) withdraw a portion of energy flowing into the switch device, (ii) store the portion of energy in an energy storage device, and (iii) supplying the energy stored in the energy storage device to one or more components within the switch device.

摘要： A plug-in summation current transformer module for insertion into a module-overlapping installation space of a multi-pole rail-mounted device that is formed of a plurality of housing modules has a summation current transformer and primary conductors routed through the tubular summation current transformer. The primary conductors have primary conductor ends. A primary conductor holder for fixing the primary conductor ends is fastened to the summation current transformer and adopts a fixing position for holding the primary conductor ends in an assembling position for insertion into a module-overlapping installation space and a releasing position where the primary conductor ends move transversely into a releasing position allowing the primary conductor ends to join into their contacts in the modules.

摘要： A circuit breaker device includes a bimetallic overcurrent protection element which is configured to be placed in series with an integrated replaceable fuse. The replaceable fuse may be faster-acting than the bimetallic overcurrent protection element, and may be higher-rated than the bimetallic overcurrent protection element. The circuit breaker device may include an electrically isolated terminal stud having a height sufficient to retain the replaceable fuse thereon, the electrically isolated terminal stud not directly connected to the bimetallic overcurrent protection element, so that current can only flow through the bimetallic overcurrent protection element when a replaceable fuse comprising an intact fuse element is supported on the electrically isolated terminal stud.

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.
