ABB OT16ET3 general purpose disconnect switch, 3-Pole, 16A, 600VAC 10HP with handle

This switch is designed for general-purpose use, such as disconnecting power to motors and other equipment. The 3-pole design is suitable for three-phase systems, and the 16-amp current rating supports loads up to 10 horsepower at 600 volts. The handle makes it easy and safe to operate and disconnect the device.

Applications:

• As main switch for electrical cabinets
• As main switch or emergency stop switch for machinery.
