It is a 32 V DC wide-range coil, meaning it accepts a broader control voltage band than a fixed-coil variant — useful when the control supply is unregulated or shared across multiple loads. Rated hold-in power consumption is 22 W at 68 °F (20 °C), with an inrush power of 22 W as well. The coil has no built-in suppressor module, so an external flyback diode or RC snubber is needed across the coil terminals if the control circuit requires back-EMF suppression. Verify the coil voltage range and mechanical fit against the existing 80 A contactor before committing — the wide-range 32 V DC coil mates only with that specific frame. The control circuit voltage limits specify drop-out at 0.1...0.3 Uc and operational at 0.75...1.2 Uc at temperatures below 131 °F (55 °C). This means the coil will reliably pick up when the control voltage is at least 75% of nominal (24 V DC for a 32 V DC nominal coil) and will drop out cleanly below about 3.2 V DC — important for fast contactor opening during a control power sag. These are the limits for high-speed cycling applications like stamping presses or rapid-transfer conveyors — most general motor-starting applications stay well below this rate. The time constant of 75 ms characterizes the coil's magnetic build-up — relevant when coordinating with the contactor's own closing time in a sequence. Ambient operating temperature range is -5...140 °F (-5...60 °C), covering typical panel environments without derating.","metaTitle":"Schneider LX4D7BNW TeSys Deca Contactor Coil, 32 V DC, Obsol","metaDescription":"Obsolete LX4D7BNW contactor coil for TeSys Deca 80 A contactor. 32 V DC wide-range, 22 W hold-in.

Any substitution requires checking the 80 A contactor frame compatibility and coil voltage range — a standard 32 V DC coil from the same TeSys Deca family may fit, but verify the mounting and electrical interface against the existing contactor."},{"question":"What is the TeSys range?","answer":"TeSys is Schneider Electric's legacy platform for contactors, overload relays, and accessories.
