Overvoltage: It cuts off the power if the voltage rises dangerously. It protects electronic devices from burning out due to power grid faults or when power is suddenly restored after an outage.
Undervoltage: Cuts off the power supply when the voltage drops too low. Protects motor-driven appliances, such as refrigerators and air conditioners, from overheating and damage.
Overcurrent: Cuts off the power if the connected devices draw more Amps than allowed, protecting the installation from overheating.
Phase Asymmetry: Checks whether there is a large voltage difference between the three phases, protecting three-phase machines from dangerous malfunctions.
Phase Sequence: Ensures the correct phase sequence so that motors and pumps do not rotate in reverse, causing damage.
Shows the maximum current in amperes that the device can withstand. Choose the amperes so they cover the overall protection of your electrical panel or the maximum consumption of the device you want to protect.
