Application Scenarios
In a large-scale automotive manufacturing plant,sudden motor failures on the production line were causing costly downtime—until the 269plus-d_o-100p-125vdc was installed.The plant’s conveyor system motors,prone to overloads due to variable part weights,frequently tripped traditional fuses,halting production for hours.After deploying the 269plus-d_o-100p-125vdc,the relay’s programmable overload curves were tailored to the motors’specific load patterns.It now detects overloads early,发出警报instead of immediate shutdown,allowing operators to adjust loads and prevent full stops.This reduced unplanned downtime by 75%and extended motor lifespan by an estimated 30%.

Technical Principles and Innovative Values
Innovation Point 1:The 269plus-d_o-100p-125vdc uses advanced algorithm-based monitoring to distinguish between temporary overloads and genuine faults.Unlike traditional relays that trigger shutdowns based on fixed thresholds,its Flex Curve™technology adapts to motor thermal characteristics,reducing false trips by up to 60%in variable-load applications.
Innovation Point 2:Integrated RTD temperature monitoring provides dual-layer protection—combining electrical fault detection with direct thermal sensing.This ensures the relay responds to both current-based issues and overheating,a feature missing in 40%of comparable relays,according to industry benchmarks.
Innovation Point 3:Modbus RTU compatibility enables real-time data transmission to SCADA systems,allowing predictive maintenance.Users can track motor health trends remotely,identifying potential issues before they cause failures—reducing maintenance costs by an average of 25%.
Application Cases and Industry Value
In a coal-fired power plant,the 269plus-d_o-100p-125vdc was deployed to protect critical boiler feed pump motors,which operate under high pressure and temperature.These motors are essential for maintaining steam production,and failures could lead to plant shutdowns costing
