Product Description
CTH-CS Spring Operating Mechanism
CTH-CS spring operating mechanism apply to ring main unit switchgear 12kV, with function of energy storage & coil open and close, both by manual and motor.
With open spring for recloser function, and interlock with disconnecting mechanism. The mechanism is compact structure and small input power, more reliable,
longer life, easy installation for RMU switchgear panel.
