Three-phase Asymmetry and Phase-sequence
Phase-loss Relay
K8AB-PA
Ideal for 3-phase voltage asymmetry
monitoring for industrial facilities and
equipment.
• Monitor voltage asymmetry, phase sequence, and phase loss
for three-phase 3-wire or 4-wire power supplies with just one
Unit.
Switch setting for 3-phase 3-wire or 3-phase 4-wire power
supply.
• One SPDT output relay, 6 A at 250 VAC (resistive load).
• World-wide power specifications supported by one Unit
(switchable).
• Relay warning status easily monitoring using LED indicator.
• Easy wiring with ferrules
