New generation, simpler commercial references We know any change in commercial references will be an adjustement, but in the long run we believe this change is needed, and will make your life easier. The table below describes how new references are build. For instance LV429630 (ComPacT Breaker NSX100F 36kA AC 3P3D 100A TMD) becomes C10F3TM100.
Buildings ComPacT NSXm devices up to 160 A (70 kA/415 V) are equipped with thermal magnetic trip units. ComPacT NSX devices up to 630A (200 kA/415 V) are equipped with Magnetic, Thermal Magnetic, basic electronic trip units (MicroLogic 2) and advanced electronic trip units (MicroLogic 5/6) which offer embedded metering and communication. Both devices can protect against insulation faults thanks to their embedded earth leakage protection. ComPacT NSXm and NSX can be easily installed at all levels in distribution systems, from main LV switchboard to the sub-distribution boards and enclosures.
ComPacT NSX DC range up to 1200 A (5 kA/600 V DC) meets the requirements of UPS manufacturers keeping the same compact footprint as the standard ComPacT NSX range. Batteries are usually used for emergency power supply and circuit breakers are used to protect the battery circuit (between the battery and the circuit) [c]. To allow a continuous supply of power, some electrical installations are connected to two power sources [d]: b A normal source. b A replacement source to supply the installation when the normal source is not available. A mechanical and/or electrical interlocking system between two circuit breakers or switch-disconnectors avoids all risk of parallel connection of the sources during switching. A source-changeover system can be: b Manual with mechanical device interlocking b Remote controlled with mechanical and/or electrical device interlocking b Automatic by adding a controller to manage switching from one source to the other on the basis of external parameters.
