Mitsubishi SD-T80-DC24V Magnetic Contactor for MS-T Series 298646

The Mitsubishi 298646 (SD-T80-DC24V) is a three-pole, non-reversing magnetic contactor from the MS-T series. It is designed for DC-operated control with a 24 V DC coil and provides a 45 kW rating at 380-440 V AC in AC-3 duty, along with 2 NO and 2 NC auxiliary contacts for control and interlocking circuits. The contactor has a rated operational voltage of 690 V, a rated impulse voltage of 6 kV, and screw-clamp terminals with finger protection. It can be mounted on DIN rail or on a flat surface, measures 88 x 106 x 133 mm, and weighs approximately 2.1 kg. This MS-T series contactor is used for direct-on-line and full-voltage non-reversing starting and control of three-phase motors in industrial control panels, machine tools, and motor-driven equipment. It is compatible with TH-T65KP overload relays specified for S(D)-T65, S(D)-T80, and S(D)-T100 contactors, allowing a compact motor starter assembly. The 24 V DC coil suits control systems that use a DC control bus, while the 2NO+2NC auxiliary contacts support status feedback, sealing, and interlock functions. The device is rated for 50/60 Hz operation and an ambient temperature range of -10 to 40°C.
