Features and benefits:

• Off-delay timer adjustable from 1 to 30 seconds enables controlled shutdown sequencing in motor circuits.
• Compatible with TeSys Deca CAD, LC1D, TeSys F LC1F, and CR1F for broad integration across the TeSys contactor range.
• Non-overlap time of 1.5 ms on both opening and closing prevents contact bridging between NC and NO states.
• Insulation resistance greater than 10 MOhm and GG fuse protection at 10 A ensure reliable circuit integrity.
• Operating range of -40 to 70°C and IP20 protection support demanding industrial environments.

Applications:

• Motor control panels requiring timed shutdown sequencing after contactor de-energisation.
• Industrial automation switchgear where auxiliary off-delay timing is needed between circuit events.
• HVAC and refrigeration control systems in compliance with IEC 60335-2-40 Annex JJ.
• Machine control cabinets built around TeSys D or TeSys F contactors.
