- Description
CAD50D7 is Schneider Electric's TeSys Deca control relay in a 5NO arrangement, built around a 42 V AC coil and a 140 A AC rated making capacity for up to 690 V circuits. Rated for AC-15/DC-13 duty between -40 and +60 °C, it duplicates and interlocks pilot signals in motor control circuits, terminating on screw clamp terminals on DIN rail or a mounting plate.

Selection Notes
Choose this 5NO variant for five make contacts, useful where one command must be duplicated to several downstream circuits without a break contact. The 42 V AC coil matches circuits already wired at that voltage, avoiding a separate step-down winding. The AC coil closes in 12–22 ms and draws 70 VA at inrush, dropping to 8 VA hold-in — the figure to size a shared control transformer against when several TeSys Deca relays operate together.
