Product abstract

The CT32 operating mechanism can be used to close and open ZF10-126, ZF5T-126, ZF12-126, ZF4A-126, ZF31-126, ZF21-126, ZF29-126, ZF25-126, ZF39-126, ZF35-126, ZF34-252, as well as disconnecting, earthing and load switches. The required torque is comparable to that of the above mentioned switches.

The closing and opening positions and output angles of the mechanism are ensured by a clutch and worm gearing through the forward and reverse function of the motor. The mechanism has both manual and electric functions.
