Features and benefits:

• 1NO+1NC instantaneous contacts enable simultaneous normally-open and normally-closed signalling from a single block
• Front mounting design allows easy addition to TeSys D and TeSys Deca contactors without replacing the base unit
• 1.5 ms non-overlap time between NC and NO contacts prevents false signals during switching transitions
• Wide compatibility across TeSys D CAD, LC1D, TeSys F LC1F, CR1F, and TeSys Deca ranges
• Rated for 30 million mechanical cycles, ensuring long service life in high-cycle applications
• Lugs-ring terminal connection with M3.5 screws provides secure, vibration-resistant wiring

Applications:

• Motor starter control circuits requiring auxiliary signalling and status feedback
• Industrial automation panels using TeSys D or TeSys Deca contactors for interlocking logic
• HVAC control systems where contactor position feedback is needed for building management integration
• Machine safety circuits requiring NC contact monitoring of contactor state
• PLC input modules receiving run/stop status signals from motor control centres
