Overload Detection

CNC machining center using Load Controls UPC for spindle load monitoring, tool break detection, and process optimization.

Motor overloads don't just damage equipment, they cause unplanned downtime, production losses, and safety incidents. Conventional overload protection reacts after damage is already underway, tripping the motor only when current thresholds are exceeded, often too late to prevent harm.

Load Controls' power sensors detect overload conditions earlier and more accurately than current-based protection alone, measuring true power draw rather than just current. Because power reflects the actual mechanical load on the motor - including power factor changes that current sensing misses, our sensors catch developing overloads sooner, triggering alarms or automatic shutdowns before equipment damage occurs. Adjustable set points let you fine-tune protection to your specific motor and process. All sensors are non-invasive, install at the motor control panel, and are manufactured in the USA to ISO 9001:2015 standards.

Q: Why is power-based overload detection better than current-based detection?

Current alone doesn't tell the full story, power factor changes mean a motor can be overloaded while current appears normal. True power measurement catches these conditions that current-only protection misses.


Q: Can I set different overload thresholds for different operating conditions?

Yes. Load Controls sensors feature adjustable set points so you can configure separate thresholds for different load phases or process stages.

Q: Will the sensor cause nuisance trips during normal motor startup?

Adjustable time delays allow the sensor to account for normal load variations during motor startup, only triggering protection once steady running conditions are established.
