Suitable for distribution network circuits with AC 50Hz, rated working voltage of 400V and below, and rated current of 63A and below;

• Provide indirect contact protection for individuals;
• Provide leakage protection for equipment;
• Overload and short circuit protection for lines and power equipment;
• Under normal circumstances, it can be used for infrequent switching of circuits and infrequent starting of motors.

The product meets the standards of IEC 61009-1 and GB/T 16917.1.

It also complies with the technical specifications for bidding of State Grid Xizang Electric Power Co., Ltd. The small leakage circuit breaker shall have the function of leakage exit.

This circuit breaker adds real-time monitoring of the remaining current value of the line on the basis of the original protection function, and has a set of passive alarm signal outputs, which can achieve remote and close range leakage alarm functions.

The working principle of the circuit breaker with optional leakage alarm and non trip function is as follows:

1. When the leakage protection function is turned on: there is no signal output, and the leakage alarm light does not light up. When the leakage current in the circuit reaches the action value, the product trips within the specified time;
2. When the leakage protection function is turned off: when leakage current is generated in the circuit, an alarm signal is output, and the leakage alarm light is always on, but the product does not trip. At this time, the circuit should be maintained in a timely manner.

Attention: When there is a leakage alarm, timely maintenance should be carried out to ensure the safety of personnel and property
