Mitsubishi SD-T20-DC48V-1A1B 3-Pole Magnetic Contactor for MS-T Series 48 V DC 7.5 kW

The Mitsubishi SD-T20-DC48V-1A1B is a three-pole magnetic contactor from the MS-T series in the T20 frame size, designed for direct-on-line (DOL) and full-voltage non-reversing motor control. It uses a 48 V DC control coil and provides one normally open plus one normally closed auxiliary contact (1NO+1NC). At 440 V AC in AC-3 duty, the contactor is rated for 7.5 kW, with an 18 A rated current at 380 V, 400 V, 415 V and 440 V AC. Its rated operational voltage is 690 V AC and its rated impulse withstand voltage is 6 kV. Screw-clamp connections with finger protection, IP20 protection and DIN-rail or surface mounting make it suitable for installation in control cabinets. The compact 43 mm width, 75 mm height and 100 mm depth help with dense panel layouts. Typical applications include direct-on-line starting and stopping of three-phase motors, pumps, fans and other machine loads controlled through Mitsubishi MS-T series contactor assemblies.
