RC transient voltage suppression Protects contactor coils For TeSys Deca contactors Side clip-on mounting 110-250V AC operation Limits transient voltage to 3 Uc

Product description

The Schneider Electric LAD4RCU is an RC transient suppressor module designed for TeSys Deca contactors (LC1D09-D38, LC1DT20-DT40) and CAD control relays. It provides protection against voltage spikes and transient overvoltages in control circuits operating between 110 and 250V AC. This module uses an RC circuit to limit transient voltage to a maximum of 3 Uc.

This suppressor is crucial for industrial control panels, automation systems, and power distribution units where protection against voltage transients is necessary. Its side-clip mounting design ensures it fits without altering the overall dimensions of the contactor, offering a discreet yet effective protection solution.
