Ecostruxure IT Expert Access for 500 nodes

This RM AirSeT is a medium voltage gas insulated switchgear (GIS). It comprises 2 functional units: 1 switch-disconnector I, 1 circuit breaker B. It applies for a rated voltage up to 24kV. The rated busbar current is 630A. The short circuit current is up to 20kA for 1s or 3s. It conforms the standards IEC 62271-200 and IEC 62271-1 for indoor installation. The familiar 3 positions switch-disconnectors use Shunt Vacuum Interruption (SVI)™ technology including load breaking, disconnecting and earthing. The circuit breakers on the top of B functional units are interlocked with 3 position disconnectors directly connected to cable bushings. Breaking / switching is insured in vacuum interrupters. The gas of disconnection and insulation is pure air. The pure air, main contacts, vacuum interrupters and busbar are preserved from ambient environment in a IP67 stainless steel sealed pressure system, for the service life. Its footprint is similar to previous generations, for applications as ring main unit (RMU) or modular unit. Opening the link on the nameplate’s QR code at site, provides a digital access to products data. Monitoring and control functionalities can be implemented with the advanced PowerLogic devices (fault passage indication, remote telecontrol units, power quality…). Some kits (motorisation…) and tutorials including videos are available for further upgrade. The dimensions are width (W): 770mm x depth (D) 780mm x height (H) 1625mm in standard 1.6 (or 1400mm in version 1.4) without extended Low Voltage cabinet. The standard operating temperature is -25°C to 40°C. The storage temperature is -40°C to 70°C.
