Omron K8AK-PA Series Monitoring Relay, 5A Contact Current, 3 Phase Electrical Phase - K8AK-PA2
This monitoring relay is designed to detect phase sequence and provide transducer-style monitoring within three-phase systems, offering protection against incorrect phase rotation and related faults. It is intended for panel-mounted automation and control installations where continuous verification of supply phasing is required, and it connects via screw terminals for secure wiring in DIN-rail-mounted assemblies.
Features and Benefits:
• SPDT contact arrangement delivering selectable output switching
• 5A contact rating for handling control and indicator loads
• Works with three-phase supplies to verify correct rotation
• Low power draw of 4.4VA for efficient control circuits
• Rated for operation between -20°C and 60°C for varied sites
• Complies with multiple safety standards for industrial use
Applications
• Suitable for phase rotation protection in motor control panels
• Used with pump systems to prevent reverse-rotation damage
• Ideal for integration into factory automation control racks
• Can be used for monitoring supply integrity in distribution boards
