The is typically designed to:
Standard 35mm DIN rail (HT35) or screw mounting via two M4 holes. Visual Status Indicators (LEDs)
Reliable operation requires proper termination. The controller uses heavy-duty terminal blocks designed for insulated copper wire. Step-by-Step Terminal Routing Connect the raw, unswitched supply lines directly to
What type of equipment () is this relay controlling?
Replacement units and detailed model variations (like the 6060009) are commonly available through industrial suppliers like AliExpress wiring diagram summary for a specific application, or do you need help troubleshooting a particular phase fault light? Connect the L3 line to terminal 3
If the phase sequence ( or L1-L2-L3 ) is cross-wired or inverted during service or initial hookup, the relay blocks startup. This prevents three-phase motors from spinning backward, which can cause catastrophic mechanical damage to scroll compressors or hydraulic pumps. Dynamic & Static Phase Loss Protection
