TeSys D suppressor module, for LC1D09-D38, LC1DT20-DT40 contactors and CAD control relays. To be used with 126-250V DC control circuit voltage, it provides a bidirectional peak limiting diodes protection limiting the transient voltage to 2 Uc max. Clip-on side mounting, overall size of the contactor is unchanged. Green Premium compliant (RoHS/REACh).
