摘要： A circuit breaker system (100) providing a low impedance magnetic latch tripping scheme. The circuit breaker system (100) includes a trip unit (310) coupled to a switch unit (108). Trip unit (310) is coupled to an electrical circuitry and utilizes a current transformer (114) to sample a current conducting through the electrical circuitry. This current is processed into an input signal (126) suitable as an input to a trip circuitry (316) included in the trip unit (310). When a processor (322) senses an overcurrent condition in the input signal (126), processor (322) transmits a trip signal (128) to a switch (220) to initiate protection against the overcurrent condition, i.e., a trip of the electrical circuitry. Switch (220) permits a low release current to conduct through a low impedance electromechanical interface unit (218) such that the electromechanical interface unit (218) can actuate a mechanical opening mechanism included in the switch unit (108).

摘要： A circuit breaker system (100) providing application specific module (ASM) instantaneous overcurrent indication is disclosed herein (FIG. 5). A trip unit (110) included in the circuit breaker system (100) is powered by an external power supply unit (134) in the ASM (104). The circuit breaker system (100) includes transmitting an indication signal (130) from the trip unit (110) to the ASM (104) in response to an overcurrent condition. The indication signal (130) triggers a first controller (130) included in the ASM (104), the first controller (130) configured to cause the external power supply unit (134) to maintain power to the trip unit (110) for a first length for time sufficient to communicate a data corresponding to the overcurrent condition to the ASM (104). The output of the first controller (130) triggers a second controller (132) included in the ASM (104), the second controller (132) configured to cause the external power supply unit (134) to reset the trip unit (110) in readiness to respond to the next overcurrent condition. The data received by the ASM (104) may be processed to form a trip and overcurrent data set for display in a display unit (112).

摘要： A portable circuit breaker tester (10) for testing a current transformer (30, 32, 34, 36) of a circuit breaker (18) having a first terminal (30e, 32e) on a first end of the transformer and a second terminal (138) on a second end of the transformer has a test port (14) configured to be coupled to the first (30e, 32e) and second terminals (138) and a test circuit (68, 74, 96, 104, 146) coupled to the test port (14). The test circuit (68, 74, 96, 104, 146) is configured to provide a test current through the test port (14) to the first terminal (30e, 32e), to monitor the second terminal (138) through the test port (14), and to provide an output signal to an indicia (38, 40) based on whether the test current is received at the second terminal (138). The test circuit (68, 74, 96, 104, 146) is configured to perform first and second testing operations on the circuit breaker (18) through the test port (14). During the first testing operation the test circuit (68, 74, 96, 104, 146) provides a test signal to a terminal (30e, 32e, 138) coupled to the current transformer and during the second testing operation the test circuit (68, 74, 96, 104, 146) provides power to the circuit breaker (18).

摘要： Disclosed is a vehicle which includes an electrical system monitoring system which results in detecting arcing in the electrical distribution system of the vehicle and the ability to provide notification and protection for such arcing. The system functions to monitor the electrical distribution system of the vehicle to sense the frequencies of signals in the system using appropriate filtering. One type of filtering which may be used is based upon a heterodyning circuit which provides variable frequency filtering for filtering a signal representative of the current in at least one electrical circuit of the vehicle. The heterodyning circuit output is configured to produce a signal which may be logarithmically related to the filtered signal. If the output signal exceeds a predetermined limit (representative of noise) for a predetermined period (representative of a typical arc duration), the system generates an arc signal. The arc signal may then be used to operate a circuit interrupter or an indicator in a circuit protection system or both.

摘要： A sputtering arc fault detector (10) for a system having an electrical conductor (14) carrying current to a load. The sputtering arc fault detector includes a current monitor (64) coupled to the conductor for generating a variable signal responsive to behavior of the current in the conductor. A level detector (58) is coupled to the monitor and generates a first pulse when the variable signal exceeds a first level. A step detector (62) is coupled to the monitor and is responsive to rapid step increases of the variable signal. The step detector generates a second pulse when the variable signal exceeds a second level. An arc verifier (48), which is coupled to the level detector and the step detector, combines the first and second pulses, and generates a fault signal when the combined pulses exceed a third level.
