ABB OT200U03 Disconnect Switch,200Amp,3P
The ABB OT200U03 is a manually controlled safety switch, especially a 3-pole disconnect switch rated at 200 amps. Electrical circuits are physically isolated from their power source in order for it to work. This eliminates the possibility of live current when working on electrical equipment, which is essential for safety and maintenance. Disconnect switches such as the ABB OT200U03 are commonly used in a variety of HVAC equipment, including air handling units, chillers, and fan coil units. Their major role is to increase the safety of persons performing maintenance or repairs on these systems by isolating them completely from the power supply. Disconnect switches reduce the possibility of accidentally coming into contact with live wires by providing visual and positive proof of unplugged power.
