6EP4437-7FB00-3DX0 SIEMENS SITOP SEL1200 5 A selectivity module 8-channel with switching characteristic Original Brand New

The SITOP SEL1200/1400 selectivity modules enable the reliable and efficient protection of load feeders in almost any application. This is ensured by the high functionality of the narrow add-on modules in various designs.

• Reliable detection of overload or short-circuit in the 24 V and 48 V circuit
• Safe tripping regardless of line resistance
• SITOP SEL1200: Switching characteristic for standard protection and high inrush currents
• SITOP SEL1400: Current-limiting characteristic for increased fuse protection requirements
• Either 4 or 8 load feeders per module with individually adjustable response threshold
  • 4 outputs 24 V, adjustable, 2 – 10 A
  • 8 outputs 24 V, adjustable, 1 – 5 A or 2 – 10 A
  • 4 outputs 48 V, adjustable, 1 – 10 A (SEL1200 48 V)
• Common signaling contact or single-channel diagnostics for voltage, current, set threshold value and reason for switch off, if applicable
• Ex variants for use in hazardous environments
• Evaluation via free SIMATIC S7 function blocks (S7-1500/1200/400/300) and faceplates for SIMATIC Comfort Panels and Unified Panels
• Library for visualization in SIMATIC PCS 7
• Simple configuration thanks to individual setting of maximum current for every output using potentiometers
• 3-color LEDs for fast on-site fault localization
• Remote reset possible from a central location
• Simple commissioning thanks to manual switch on/off of outputs
• Sequential connection of feeders to reduce total inrush current
• Sealable transparent cover over adjusters for currents and times protects against maladjustment
• Push-in terminals for fast wiring
• In the design of SITOP PSU6200 power supplies
