Description
Three-phase Voltage Relay
K8AB-PW
CSM_K8AB-PW_DS_E_2_1
Ideal for monitoring 3-phase power supplies for industrial facilities and equipment.
Monitor overvoltages and undervoltages for three-phase 3-wire or 4-wire power supplies. DIP switch setting for 3-phase 3-wire or 3-phase 4-wire power supply. Two SPDT output relays, 6 A at 250 VAC (resistive load). Separate outputs possible for overvoltages and undervoltages. World-wide power specifications supported by one Unit (switchable using DIP switch). Relay status can be monitored using LED indicator.
Refer to Safety Precautions for the K8AB Series. Refer to page 9 for the Q&A section.
