- Description
The Schneider Electric LC1DT25B7 is a TeSys Deca 4-pole (4NO) contactor rated 25 A AC-1 for non-inductive loads at up to 690 V. It takes a 24 V 50/60 Hz AC coil, a low-voltage control standard on machine panels, and 1NO+1NC mirror-certified auxiliary contacts come built in. Screw clamp terminals serve both the power and control circuits.

Selection Notes
The LC1DT25B7 switches 25 A AC-1 uniformly across all four poles, making it a fit for resistive heater or lighting banks that need four-pole isolation rather than three-phase motor duty. A 24 V AC coil matches the control-transformer secondary used on most European machine-tool panels. For the same coil voltage at higher resistive current, the 32 A and 40 A LC1DT variants share the same technology.
