Thermal overload relay for fast, reliable motor protection Key benefits Prevents motor damage: Detects motor overload quickly and reacts to cut or limit current, reducing the risk of burnt windings and extended downtime. Dependable operation: Uses the current-based thermal effect principle with a stable internal structure to deliver consistent overload protection across different environments. Flexible protection settings: Trip threshold is adjustable so you can match protection to the actual motor load and operating conditions. Broad compatibility: Designed to protect a wide range of motor types and to work in varied industrial and commercial environments. What it does Monitors motor current and responds to sustained overcurrent conditions with a thermal trip mechanism that mimics motor heating, providing a realistic and effective overload cutoff. Offers repeatable, predictable protection performance without relying on complex electronics. Important attributes Function: Thermal overload detection and tripping for motor protection. Compatibility: Suitable for numerous motor types and protection schemes; applicable across diverse working environments. Construction: Stable, robust design based on the thermal current effect to ensure long-term reliability. Performance: Rapid detection and reliable response to overload conditions; adjustable trip point for tailored protection. Typical applications Industrial production lines: Protects drive motors on conveyors, presses, and machine tools from overload-related damage. Pumps and HVAC systems: Safeguards pump and fan motors in water treatment, heating, ventilation, and air conditioning installations. Compressors and material handling: Prevents motor failure in compressors, lifts, and automated handling equipment. How it helps you Reduces unplanned downtime and maintenance costs by detecting overloads early and protecting the motor. Allows configuration of trip thresholds so protection matches actual operating needs, avoiding nuisance trips while maintaining safety. Provides a straightforward, proven method of motor protection that integrates with common motor control setups. For applications where reliable, adjustable overload protection is required, this thermal overload relay offers a simple, effective solution without adding unnecessary complexity.
