ComPact NSX offers a complete range of high-performance compact circuit breakers (MCCB) in two frame sizes. The breakers are designed to meet your needs, from thermal-magnetic protective relays up to MicroLogic protective relays equipped with extended protection and monitoring features. The MicroLogic protective relays also include MicroLogic Vigi protective relays that save installation space, as earth fault protection or monitoring is built into the relay functions. The VigiPacT earth fault protection module is an external accessory for the ComPact NSX breaker, installed on the breaker's output. The earth fault module can be either tripping or alarming. The setting range is adjustable from 30 mA to 3 A. In tripping earth fault modules, a time delay can additionally be set from 0 ms to 4 s.
