Product details

The LX4D7TD is a replacement coil for the TeSys Deca range of contactors, specifically wound for a 305 V DC control circuit and intended for an 80 A frame contactor. It is a DC-standard coil with no built-in suppressor module, meaning you'll need to add an external flyback diode or RC snubber across the coil terminals to protect the control circuit from the inductive kick when it de-energizes.

Rated for 305 V DC control voltage, with a drop-out threshold of 0.1 to 0.3 Uc and an operational range of 0.85 to 1.1 Uc. Hold-in and inrush power consumption is 22 W at 20 °C, with an average coil resistance of 4486 ohms. That's a steady-state current draw of about 68 mA at nominal voltage — well within the capacity of a standard PLC digital output or relay, but check your driver's current rating if you're switching it directly from a card.
