Automatic circuit breaker tester UPA-3 is designed for testing and ampere-second characterization of automatic AC current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switching interval. Circuit breaker tester UPA-3 is a mobile device, which could be easily transported to a required testing location. Circuit breaker tester UPA-3 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (RNO or VR) or through a built-in thyristor controller.

Introduction The LWâ?¡-252/4000-50 self-extinction Ac circuit breaker which is outdoor type finds its universal range of applications for the electrical system with elevation not greater than 2000m, ambient temperature not lower than-30C, dirtiness grade not higher than IV, alternating current 50Hz and the maximum voltage 126kV. It is used for cutting the rated current, malfunction current or switching the circuitry, to control and protect the electrical system, and it can also be used for connecting with the circuit breaker The gas of the SF6 is employed as the arc-extinguishing medium and the dielectric material. The self-extinction technology and the new-type spring operating mechanism are introduced in the SF6 circuit breaker. Thus the circuit breaker has good qualities with long electrical life, low operation power, lower noise, high reliability, simple structure, small and long overhaul periods. It can fully replace the import same type one. Caracteristic of structure The breaker introduces the three-phase porcelain -pole with single interrupter structure. A spring operating mechanism is supplied and the mechanical action of the three-phase is inner connected. The gas of the SF6 is connected in the three-phase pole parts. A density controller with temperature compensation is used to monitor the gas of the SF6.

An essential electrical safety tool that guards against electric shock and other electrical dangers is a residual-circuit current breaker (RCCB). It detects the difference in electric current flow between the live and neutral wires and shuts off the circuit if a fault is found. In residential, commercial, and industrial applications, an residual circuit current breaker is often placed in the distribution board or consumer unit. Residual-Current Circuit Breakers are intended to offer better defense against electrical fires and shocks brought on by other electrical faults, including ground faults. They are a crucial part of electrical safety and are needed in most nations due to laws and regulations. Advantages of Using Residual-Current Circuit Breakers in Electrical Systems Enhanced Safety Residual-current circuit breakers offer enhanced safety by instantly cutting off the power supply to a circuit in the event of an earth leakage or a fault current. This reduces the risk of electric shock or fire caused by an insulation fault.
