CONTACTORS AND STARTERS-IEC
[18] Installing the suppressor into the cavity makes the electrical connection. Overall width of the contactor remains the same.
[19] For LC●D09–LC●D65A with DC or low consumption DC coils, 3-pole contactors are fitted with built-in bidirectional diode suppression as standard.
[20] Mounting at the top of the contactor on coil terminals A1 and A2.
[21] For 24 V operation, the contactor must be fitted with a 21 V coil: coil voltage code Z5 for 50 Hz; Z6 for 60 Hz; and ZD for DC.
[22] Adapter required for D09–D65A, see .
