Phase-sequence Phase-loss Relay
K8AB-PH
Three-phase Phase-sequence Phase-loss
Relay Using Voltage Detection Method
• Prevents reverse motor rotation due to incorrect wiring.
• Distinguishes between positive phases, reversed phases, and
phase loss when power is turned ON.
• Voltage detection method enables application for any load
current.
• One SPDT output relay, 6 A at 250 VAC (resistive load).
• Output status can be monitored using LED indicator.
Refer to Safety Precautions for the K8AB
Series. Refer to page 5 for the Q&A section.

Meaning
Power indicator
(PWR: Green)
Lit when power is being supplied (see note).
Relay status indicator Lit when relay is operating (normally lit).
(RY: Yellow)
Note: 1. The input across L1 and L3 is used for the internal power
supply. Therefore, the power indicator will not be lit if there
is no input across L1 and L3.
2. Use either a solid wire of 2.5 mm2 maximum or a ferrule with
insulating sleeve for the terminal connection.
The length of the exposed current-carrying part inserted
into the terminal must be 8 mm or less to maintain dielectric
strength after connection.
For 2.5 mm2 or
smaller solid wires
For ferrules with
insulating sleeves
8 mm max.
Recommended ferrules
Phoenix Contact
Al 1,5-8BK (for AWG16)
Al 1-8RD (for AWG18)
Al 0,75-8GY (for AWG18)
3. Tightening torque
Recommended: 0.49 N·m
Maximum: 0.54 N·m
8 mm max.
Operation and Setting Methods
Connections
1. Input
Connect using L1, L2, and L3.
Make sure the phase sequence is wired correctly. The Unit will not operate normally if the phase
sequence is incorrect.
2. Outputs
Terminals 11, 12, and 14 are output terminals for SPDT.
