Compact NSX2550F Circuit Breaker, 3 Pole
This compact, 36 kA space saving MCCBs, part of Siemens NSX range, has been designed with reliability in mind and can operate in the most stressful environments, an excellent choice for standard and specific industrial applications. With thermal magnetic trip technology and embedded earth leakage protection, this MCCB helps protect industrial installations against insulation faults. Space saving and easy to install by simply clicking into place.
Small is size but packed with innovation such as rota-active breaking technology which helps extend the life of your installation. This capable MCCBs features Everlink terminations, which is a creep compensating technology built into the terminals, helping to maintain consistent pressure on the cable during operation.
Dependable, these MCCBs combine intelligent metering and monitoring with advanced protective functions and can be connected to Schneiders EcoStruxure Power architecture. Through this platform users can anticipate and prevent issues throughout lifecycle of their equipment by measuring performance data and offering performance analysis,
