Residual current circuit breakers

Transcription

1 circuit breakers (RCCB) The residual current circuit breakers are most up-to-date devices mainly used for protection against indirect contact, but in some cases also against direct contact. The residual current breaker automatically starts to operate if the defect current (eg. insulation defect, short circuit etc.) in the protected network exceeds a critical value. Installation is suggested and in some cases even compulsory, in outdoor connections, in building site boxes, concrete mixers, bathrooms, etc. Over 6000 A independent short circuit current one must be use a shunt fuse!

The RCCB switches off automatically when the leakage current is too high on the protected network. Being portable, it can be used for any network not provided with residual current protection. The device can be switched on by the RESET button. Before first use the operation of the device must tested by the TEST button; after pushing the button the device has to switch off the plug from the network. While using the device continuously it must be tested monthly by pushing the TEST button. After installing the adaptor the protected device or net can be plugged into the socket-outlet.

4 Motor-driven automatic re-connection device General description of operation: This device automatically re-connects the previously disconnected consumer (due to overcurrent generated by failure or atmospheric phenomena), once the current into the circuit has fallen back into the normal range. Such devices are an advantage in places where circuit break-off is expected to take long until the arrival of the service personnel (telecommunication stations, traffic control by signal lamps, remote control switching devices). The cause of the overcurrent is usually transitory, long tome interruption is unnecessary and causes important disturbance. Operation properties Re-connection devices are easy to be installed and adjusted. For automatic operation just pull the convex cover in the direction of the O arrow. If the re-connection device fails to re-connect the controlled circuit breaker after the pre-set number of attempts (1-8), the break-off status will persist. Once the defection causing break-off was eliminated, the contactor can be switched on manually. For maintenance work on the circuit, before switching off the circuit breaker, the convex cover of the re-connection device shall be pushed in the direction of the OFF arrow; otherwise the reconnection device will automatically switch on the circuit breaker. To prevent unwanted reconnection, the re-connection device can be locked.

5 Control units of device The control units of automatic reconnect device can be found on the right side of dome cover as follows: The potential-independent auxiliary contacts and the remote operation contacts can be found in one row next to each other. The possible connections are: C open auxiliary contact, O close auxiliary contact, connection for O remote pushbutton connection for O remote pushbutton With Reset Counter button user can reset the digital release counter and the device is getting back to normal operation state. The Power ED with changeable color can inform the user about operation state of device as follows: - Green: normal operation; - Red: locked; - Blinking red: reconnection operation is under process. With the help of the button found on the left side of the next row, user can select the number of reconnection attempts (1; 2; 4; 6 or 8). With the button on the right side of this row one can select the delay between reconnection attempts (10; 30; 60; 120 or 180 sec). Under these buttons the digital displayed release counter was placed. Under the display were placed the connection terminals ( and ) for power supply of automatic unit Slider switch IECEE-CB CERTIFICATE O. SEMKO CERTIFICATE O.
