Phase Monitoring Relay — Model SIP-1A05 What it does Continuously monitors three-phase power to detect phase loss, phase reversal, phase imbalance, and abnormal voltage conditions. Protects motors, compressors, pumps, and other three-phase equipment from damage caused by incorrect supply conditions. Key benefits Prevents equipment failure and costly downtime by tripping or signaling before damage occurs. Provides fast, reliable detection of common three-phase faults so corrective action can be taken immediately. Reduces maintenance time and repair costs by catching supply issues early. Customizable to fit control and protection schemes (is_customized: Yes). Important attributes Function: Phase monitoring for three-phase power systems; fault detection and signaling for phase loss, sequence errors, imbalance, and voltage anomalies. Compatibility: Designed for integration with industrial control panels, motor starters, contactors, and PLC-based control systems where three-phase protection is required. Size and mounting: Compact, panel-friendly form factor suitable for space-conscious control enclosures (verify mounting requirements with supplier). Material and construction: Built for industrial environments with a durable housing and reliable electrical connections (consult datasheet for specifics). Performance: Intended for continuous operation in three-phase monitoring roles; precise response behavior and reset/trip control depend on configuration and wiring. Packaging and safety Package: Other High-concerned chemical: None Model and ordering Model Number: SIP-1A05 Customization available as specified on order (is_customized: Yes). Confirm required configuration and options when ordering. Practical use scenarios Manufacturing plant motor protection: Install SIP-1A05 on motor control panels to detect phase loss or reversal and stop the motor before overheating or bearing damage occurs. HVAC and pumping systems: Protect pumps and chillers from running on imbalanced or single-phase supply that shortens equipment life and reduces efficiency. Backup generation and transfer systems: Monitor incoming generator and utility supply to ensure correct phase sequence and voltage balance before automatic transfer and synchronization. Installation and integration tips Mount in the control panel near the protected device and wire per the system wiring diagram. Coordinate with motor starters, overload relays, and PLC inputs for reliable trip or alarm actions. Specify required customization at purchase to ensure settings and outputs meet your control logic. For configuration details, wiring diagrams, and environmental ratings, request the SIP-1A05 datasheet from your supplier.
