Definite purpose contactors

SD-Q DC interface contactors designed to directly driven by the transistor output DC24V are DC operated contactors of compact size and high ability.

The contactors is specially designed for the dynamic brake circuit of the motor, the switching of motor starting resistance, switching of emergency light. 2 or 3 NC(normally closed contact) main contacts.

The contactors are designed for DC circuits,that is the variable-speed drive-control curcuits(SCR switching circuit) and DC motor control circuits.

The contactors are designed for applications with frequent inching operations such as hoists and cranes. The contactors have a reinforced main contact compared to standard contactors.

The contactors are specially designed for the areas of mining,pumping,sawing and other applications where voltage above 1500VAC are frequently used.
A large-capacity vacuum magnetic contactor boasting high-performance, long lifespan and maintenance-free characteristics through combination.
