| 24 | Electronic tripping device for a circuit breaker | US09701401 | 2001-03-05 | US06603649B1 | 2003-08-05 | Thomas Müller; Ulrich Baumgärtl; Wolfgang Röhl; Holger Hochgraef |
| An electronic tripping device for a circuit breaker contains circuitry for simulating the response curve of a fuse. This circuitry can be controlled by a single setting mechanism representing the nominal currents or rated currents of fuses. This improves the coordination of protection in sophisticated power supply equipment containing both circuit breakers and fuses. Tripping devices equipped with microprocessors or operating in an analog fashion can be configured for the mode of operation. The new protection system achieves particularly safe operation for the user in that the setting mechanism is combined with a rating plug for the “fuse” mode, thus directly setting the tripping device to one current value. In a manner similar to a true fuse, consequently, the setting mechanism is provided with appropriate labeling. The simulated curves may contain a point of inflection below a limit in a lagging manner, to increase the nominal switching capacity and selectivity limit of a circuit breaker. | ||||||

| An improved circuit breaker comprises an externally accessible plug-in type replaceable rating adjuster removably supported on the housing of the circuit breaker. The rating adjuster comprises resistor means having a first resistance value. The plug-in rating adjuster can be removed and replaced by another plug-in rating adjuster comprising resistor means having a different resistance value to thereby enable a rating change of the circuit breaker in the field. Interlock means is provided to automatically trip the circuit breaker if the circuit breaker is closed when the rating adjuster is removed and to maintain the circuit breaker in a tripped condition so long as the rating adjuster is removed to thereby prevent operation of the circuit interrupter while the rating adjuster is removed. Keying means prevents the mounting of an improper rating adjuster on the breaker.
