Susol Series Contactors
MC-(D), a contactor or special use, is adjusted for switching single-step or multiple-step condenser bank.
It is standardized by IEC-60947-4941, UL and CSA.
When the switch is closed condenser must be discharged before recharged. (Maximum residual voltage at terminals ≤ 50V)
In working voltage 500V(Ue=500V), 100,000 times for MC-9(D)~32(D) and 80,000 times for MC- 35(D)~95(D).
To prevent short current, gG type fuse must be 1.5~2 times than rated current.
It must be separated from resistant wire
