WIRING DIAGRAM
Wiring explained:
Input:0.2-30A
Output rating：0.3A@240V AC/DC
Normally open:
When the current through the perforated line is greater than the set value, the output terminal is connected When the current through the perforated line is less than the set value, the output terminal is disconnected
Normally closed:
When the current through the perforated line is greater than the set value, the output terminal is disconnected When the current through the perforated line is less than the set value, the output terminal is connected
Dimensions:65*25*47MM
Application examples： 1. Linkage switch between two devices
2. Whether the monitoring equipment is working properly
3. Send a witch signal to PLC
4. Give the switch signal when the current is overloaded

FAQ
Q1: Are you a manufacturer?
Answer: Yes, we start from the circuit board patch, then welding, assembling one-stop production, and have our own finished product warehouse.
Q2: Have your products passed CE, FCC, ROHS certification?
Answer: Yes.
Q3: Is there any stock?
Answer: Small batch orders, such as several hundred pieces, are available in stock in normal warehouses. When the quantity is large, a certain production cycle is required, and communicate and negotiate when ordering.
