These protection elements can be used for a variety of applications, such as
• Undervoltage protection — For voltage sensitive loads, such as induction motors, a drop in voltage increases the
drawn current, which can cause dangerous overheating in the motor. The undervoltage protection feature can be
used to either cause a trip or generate an alarm when the voltage drops below a specified voltage setting for a
specified time delay.
