Schneider Electric Harmony Phase Control Relay, Slim Design 3-Phase Supply Monitor for Sequence, Failure, and Imbalance, 208–480VAC, 0.69" Width with Tamper-Proof Cover for Pumps, Lifts, Packaging

Harmony Control Monitoring and Control Relays monitor and detect abnormal operating conditions concerning phase, current, voltage, frequency, speed, or temperature. The relays inform users of abnormal conditions and allow them to initiate the necessary corrective actions before serious and costly breakdown can occur. Harmony phase control relays detect all possible faults occurring in the phases. Harmony voltage and current control relays ensure your equipment is powered with proper values. Harmony frequency control relay monitors frequency variation from your power generation line. The product monitors its own power supply, when the power supply is abnormal, the output relay de-energizes. Applications for these Harmony relays include hoisting, construction cranes, harbor cranes, packaging, construction elevators, passenger elevators, escalators, textile, water and waste water.

• PHASE MONITORING FOR SYSTEM SAFETY: The Harmony 3-Phase Supply Control Relay detects phase failure, sequence errors, undervoltage and overvoltage, and imbalance in 3-phase power systems to protect sensitive equipment from costly breakdowns and unsafe oper
• ULTRA-SLIM DESIGN: With the same width as a 1-pole circuit breaker, this compact relay streamlines panel layout and helps reduce installation time and material costs
• SELF-MONITORING FOR RELIABILITY: This electrical component monitors its own power supply and automatically de-energizes the output relay in abnormal conditions, ensuring fast response and equipment safety
• TAMPER PROTECTION: The durable transparent cover design deters unauthorized access while minimizing maintenance interruptions and protecting internal components
• VERSATILE APPLICATIONS: This relay is ideal for use in hoisting, elevators, packaging lines, textiles, water treatment, and pumping systems, anywhere consistent phase control is critical
