Type test of a switching device
 Knebl, Ladislav ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
Protection of the electrical ciruits in electrical installations by circuit breakers is the most common way of protecting circuits from overcurrents. In the low voltage installations, fuses were replaced by the circuit breakers. For this reason, it is important to put great emphases on their quality and user safety . This thesis deals with principle of the circuit breaker, its function, construction requirements and requirements for the type test, which the manufacturer needs to pass before release the device on market. These requrements are listed in Czech Technical Standard ČSN EN 60898-1. In this thesis, specific type of circuit breaker will be also described. Some sequences of tests described in the standard will be performed on that breaker.
