All protection parameters such as overvoltage, undervoltage, power limit, leakage protection, etc. can be set according to the power demand to ensure that the protector can instantly cut off the power supply in case of overvoltage, undervoltage, short circuit, leakage and other faults in the line, protecting the electrical equipment from damage.<\/p>\n
This series of products has a compact structure, beautiful appearance, and standard guide rail installation. It is mainly suitable for school dormitories, rental houses, and other occasions.<\/p>\n
2\u3001Product working principle<\/h2>\n
\n
Example:\u00a0Product default parameters: Single power is 0.2kw, limited to 3 times, total power is 2.0kw<\/p>\n
a\u3001 Connect 10 appliances with a power of less than 0.2kw separately, and at this time, the individual power does not exceed 0.2kw, and the total power does not exceed 2.0kw. The protector is working normally. If the single power of the connected electrical appliances does not exceed, but the total power exceeds 2.0kw due to too many connections, the protector will disconnect within the specified time, and manual reset is required at this time.<\/p>\n
b\u3001 When a single electrical appliance is connected with a power greater than 0.2kw, the red light P of the product flashes, indicating that an appliance with excessive power has been connected. If the load power supply is not disconnected and cut off in a timely manner within the specified time, the product will enter a countdown. When the countdown ends, the product will automatically close. If there are still over limit appliances after closing, the product will automatically disconnect. After exceeding the limit for more than 3 times, the reset button must be manually pressed to close the circuit.<\/p>\n
c\u3001 If the power of a single appliance does not exceed the limit, but exceeds the total power, the product must be manually reset to close after protection.<\/p>\n
When manually pressing the reset button is required, all over limit electrical appliances need to be removed<\/p>\n
