TeSys D suppressor module, for LC1D40A-D80A, LC1DT60A-DT80A contactors. To be used with 12-24V AC or DC control circuit voltage, it provides a bidirectional peak limiting diodes protection limiting the transient voltage to 2 Uc max. Clip-on front mounting, overall size of the contactor is unchanged. Green Premium compliant (RoHS/REACh).
