The APSW-DC75 is a Solid State DC Contactor capable of switching 75 amps DC current continuously at a nominal 750 VDC bus voltage. With solid state contacts configured as a Low Side switch, it provides a switch closure between the 750V RETURN signal (RET. terminal) and the output terminal when the switch is energized. The switch is controlled by an opto-isolated control signal, which accepts 24 VDC input. When 24 VDC is present at the control input the switch output is closed; when 24 VDC is removed from the control input, the switch output is opened. DC contactor is suitable for the circuits with rated voltage up to 660V and rated current up to 32A for remote making and circuit breaking. It is mainly used for the electric equipment in metallurgical factories, steel rolling factories and cranes. This product conforms to the standard of Q/HY022-200. |

Typical applications are lifts, transport cooling and refrigeration, where control voltage is DC and a high inrush current is no problem. Combined with a thermal overload relay, a DC contactor switches and protects induction motors against overload and asymmetric loads.Ideal for regenerative and non-regenerative systems requiring limited interrupting capacity, such as gas and oil well drilling equipment, transit and rail systems, adjustable speed drives, electic haul trucks, mining machinery, fuel cells, uninterruptible power supplies, and crane controls. Features: UL recognized/CSA certified Non-polarized arc chute design Optional Over Current Hold-In Bifurcated main contacts Silver-plated current carrying-parts High dielectric and mechanical strength Special ratings available—consult Hubbell Industrial Controls |
