Toshiba International CD231-EA1AB DC Contactor

The Toshiba CD231-EA1AB DC Contactor is a 440 VDC, 5 A electromagnetic DC switch engineered for reliable control of DC power in industrial automation and power distribution systems. Its panel-mount design is commonly used in industrial control panels, railway and battery-powered applications, and OEM machinery that require robust DC circuit switching and isolation. The device uses a DC electromagnetic coil (voltage configuration model dependent) to energize contacts for DC motor control, battery systems, and other DC loads, delivering targeted switching and control without compromising safety. This legacy OEM component from Toshiba carries the manufacturer part number CD231-EA1AB and is often replaced by Toshiba CD231-EA2AB, CD231 Series DC Contactor, or CD250 Series DC Contactor in maintenance and retrofit projects. Typical use cases include OEM replacement, control panel upgrades, and industrial electrical repair of DC power systems.
