Schneider Electric LAD4BB3 Contactor Retrofit Coil Adapter

Product Description

The SCHNEIDER ELECTRIC LAD4BB3 is a retrofit coil adapter designed for use with TeSys D series contactors. This accessory allows technicians to replace or upgrade the coil assembly in an existing contactor without replacing the full unit, reducing downtime and material cost on industrial control panel service calls. At 0.07 pounds and a compact 2.5 x 2.5 x 1 inches, the LAD4BB3 fits neatly into the existing contactor body. It is installed by licensed electricians and industrial maintenance technicians working on motor control and load switching equipment.

The LAD4BB3 is intended for use in commercial and industrial electrical systems where TeSys D series contactors are deployed for motor starting, lighting control, or general load switching. It is compatible with LC1D40A through D65A frame contactors, covering a range of amperage ratings common in three-phase motor control applications. This makes it a practical service part for maintenance programs that keep TeSys D contactors in service rather than replacing entire assemblies.

Installation Notes

Installation should be performed by a qualified electrician. De-energize and lock out the panel or control circuit before removing or installing the coil adapter, following NFPA 70E arc flash and lockout/tagout procedures. Verify that the replacement coil adapter matches the voltage rating required by the control circuit before re-energizing. Refer to the TeSys D contactor installation documentation for proper seating and retention of the coil assembly.
