The SEN Plus system has been designed from the outset based on customer requirements. The result is a product that offers unrivalled flexibility and user safety, backed up by comprehensive testing and support for many applications.
SEN Plus system can meet the most demanding requirements, from high current applications up to 7600A, down to motor control applications for a few kW. Furthermore, the system is available in different configurations, which include:
Height 2000 / 2200
Depth 600 / 800 / 1200
Width 400 / 500 / 600 / 800 / 1000 / 1200 / 1400
Degree of protection IP30 / IP41 / IP42 / IP54
Form of internal separation up to Form 4b
Color RAL 7035
Type tested IEC/EN 61439-2
Internal arc tests IEC/TR 61641
Seismic withstand UBC
Marine certification ABS
Rated operational voltage Ue 690V AC / 600V DC
Rated frequence f 50 / 60Hz
Rated impulse voltage / Overvoltage category Uimp 8kV / III
Rated current horizontal busbars up to 7600A
Rated current vertical busbars up to 2700A
Peak withstand current - horizontal busbars (Ipk) up to 220kA
Short time withstand current - horizontal busbars (Icw) up to 100kA-1s / 50kA-3s
Complete system control
Communication and control increasingly forms part of a system – data exchange via Profibus or Modbus is available for most components, to ensure a homogeneous setup. SEN Plus complies with following international standards and is tested at independent test bodies e.g. IPH, KEMA/DEKRA, ABS etc.
