Leak monitoring also helps detect insulation failures in conductors and loads. This type of fault can also jeopardize the continuity of supply to the installation, resulting in service outages and considerably higher operating costs.<\/p>\n
As a result, installing residual current protection relays ensures service continuity in your installation<\/span>, avoiding drops in productivity rates and economic losses due to service outages.[\/vc_column_text][vc_column_text]<\/p>\n A protection relay must obviously trip when there is a leakage current to ground that can put people, loads or the installation itself at risk.<\/p>\n Many of the RCD trips in facilities are the result of the new technologies that are present in the connected loads. Many of them currently rely on power electronics for their control, which improve their performance but create a series of problems in the installation.<\/p>\n Loads such as variable-speed drives, solar inverters or electric vehicle chargers are some examples of this type of technology. This type of load has to be connected through EMI filters so as not to couple electrical noise to the installation, which could hamper its operation.<\/p>\n However, simply by virtue of being connected, they generate earth leakage (they have integrated capacitors connected to ground), which increases as the voltage in the installation goes up, and even in the presence of voltage harmonics, which can cause nuisance trips of RCDs.<\/p>\n RCDs<\/a> must thus be designed to avoid nuisance trips caused by the normal operation of loads, and even by other transitory phenomena that occur when loads are connected or disconnected.[\/vc_column_text][vc_message message_box_color=”grey” icon_fontawesome=”fas fa-arrow-right” css=”.vc_custom_1712752123842{margin-top: 1rem !important;}”]The CBS-40A<\/strong> and CBS-400A<\/strong> protection units have an ultra-immunized system<\/span> that prevents trips below 85% of their rating, so if we have a high level of leakage caused by EMI filters, we will have a better performance margin without trips at non-hazardous levels.[\/vc_message][\/vc_column_inner][\/vc_row_inner][vc_column_text]<\/p>\n [\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/2″][vc_single_image image=”48525″ img_size=”medium” alignment=”center” style=”vc_box_rounded” css_animation=”fadeIn” css=”.vc_custom_1712554549679{background-color: #e7e7e7 !important;border-radius: 5px !important;}”][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image image=”48565″ img_size=”medium” alignment=”center” style=”vc_box_rounded” css_animation=”fadeIn” css=”.vc_custom_1712554557302{background-color: #e7e7e7 !important;border-radius: 5px !important;}”][\/vc_column_inner][\/vc_row_inner][vc_column_text]\u2013<\/strong> Residual current protection and monitoring units<\/p>\n The CBS-40A<\/strong> and CBS-400A<\/strong> units are the perfect solutions for protecting up to 4 loads or circuits, completely independently, guaranteeing the best service continuity thanks to all the features offered by the ultra-immunized system<\/span>.<\/p>\n This solution is ideal for protection panels where there is more than one load or line to be protected, offering a reduction in both size and cost.<\/p>\n Ideal for preventive maintenance, with local or remote display, and offering high immunity against transients and harmonics.[\/vc_column_text][vc_column_text css_animation=”left-to-right” css=”.vc_custom_1712754591734{padding-top: 1rem !important;padding-bottom: 1rem !important;}”]\u203a 4 individual channels in a single device Devices without ultra-immunized systems can trip due to a leakage that is 50% above their rating, as required by the regulation on RCDs, which can cause a trip with a leakage current that is much lower than the trip limit.<\/p>\n The CBS<\/strong> residual current protection units have an ultra-immunized system to better guarantee continuity of supply in the installation.[\/vc_column_text][vc_column_text css=”.vc_custom_1712754873294{margin-top: 20px !important;margin-bottom: 20px !important;}”]<\/p>\n [\/vc_column_text][vc_row_inner content_placement=”middle” css=”.vc_custom_1712555592015{margin-bottom: 2rem !important;padding-top: 1rem !important;padding-right: 1rem !important;padding-bottom: 1rem !important;background-color: #426da8 !important;border-radius: 5px !important;}”][vc_column_inner width=”1\/4″][vc_single_image image=”35520″ img_size=”100×100″ alignment=”center” css_animation=”fadeIn”][\/vc_column_inner][vc_column_inner width=”3\/4″][vc_column_text css_animation=”fadeIn”]<\/p>\n Tripping range between 85%-100%<\/strong> of sensitivity.

If we don’t use a relay with an ultra-immunized system, it is possible for the combined earth leakage current to be below 300 mA and for the device to trip as low as 150 mA, a threshold that is well below 300 mA, the value at which a current starts posing a danger to people.<\/p>\n Therefore, there is a real leak that is not dangerous to people or to the installation that is causing the RCD to trip, causing service outages and raising the indirect costs of the installation.<\/p>\n To prevent this effect, we suggest installing ultra-immunized RCDs that are guaranteed not to trip below 85% of the circuit breaker’s rating. In other words, continuing with the example above, these devices will only trip with currents above 250 mA, without ever exceeding the 300 mA required by the protection system, and bringing the trip value as close as possible to the actual rating of the RCD.[\/vc_column_text][vc_single_image image=”48626″ img_size=”full” alignment=”center” style=”vc_box_rounded” css=”.vc_custom_1712826105640{margin-bottom: 10px !important;background-color: #f2f2f2 !important;border-radius: 5px !important;}”][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text css_animation=”bounceIn” css=”.vc_custom_1712755561715{margin-bottom: 40px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;background-color: #782f3d !important;border-radius: 3px !important;}”]<\/p>\n It can trip!<\/p>\n [\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text css_animation=”fadeIn” css=”.vc_custom_1712755617310{margin-bottom: 40px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;background-color: #00b388 !important;border-radius: 3px !important;}”]<\/p>\n Does not trip up to 250 mA<\/p>\n [\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=”.vc_custom_1712755637051{margin-top: 20px !important;margin-bottom: 20px !important;}”]<\/p>\n [\/vc_column_text][vc_row_inner content_placement=”middle” css=”.vc_custom_1712555568631{margin-bottom: 2rem !important;padding-top: 1rem !important;padding-right: 1rem !important;padding-bottom: 1rem !important;background-color: #ffbf3f !important;border-radius: 5px !important;}”][vc_column_inner width=”1\/4″][vc_single_image image=”35536″ img_size=”100×100″ alignment=”center” css_animation=”fadeIn”][\/vc_column_inner][vc_column_inner width=”3\/4″][vc_column_text css_animation=”fadeIn”]<\/p>\n Filtering of high-frequency leaks<\/strong>.
