Three-phase Phase-sequence Phase-loss Relay
K8AB-PM
Ideal for monitoring 3-phase power supplies
for industrial facilities and equipment.
• Monitor overvoltages, undervoltages, 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.
• 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).
• Relay warning status easily monitoring using LED indicator.
• Easy wiring with ferrules
