The Single Phase Preventer INT-501 is a dedicated protective relay engineered to shield single-phase motors from the damaging effects of electrical supply irregularities. It vigilantly monitors for low voltage, high voltage, overload, and complete phase failure, conditions that can lead to immediate motor burnout or gradual degradation. Upon detecting a fault, the device triggers a precise shutdown with a configurable delay, preventing costly damage. Housed in a compact, durable metal enclosure, the INT-501 features clear LED indicators for status monitoring and is designed for straightforward wall mounting. With an operating voltage of 230V, a maximum current rating of 10A, and a wide trip voltage range of 180-270V, it offers reliable protection tailored for common single-phase motor applications, backed by a one-year warranty for assured performance.

This device finds critical usage across industries and settings where motor reliability is non-negotiable. In agriculture, it protects irrigation and water pumping systems from erratic rural power supplies. For residential and commercial infrastructure, it secures water supply pumps for overhead tanks and underground sumps. Small industrial workshops and manufacturing units rely on it to guard motors in essential machinery like compressors, lathes, and conveyor belts. The INT-501 is also deployed in commercial establishments such as cold storage facilities, laundries, and retail environments to ensure the uninterrupted operation of refrigeration and air conditioning systems, where motor failure can lead to significant product or operational loss.

The business value of the INT-501 lies in its role as an affordable insurance policy for your motor-driven assets. Its primary benefit is risk mitigation; by preventing motor burnouts, it avoids expensive motor replacements, unplanned downtime, and lost productivity. The device enhances operational efficiency by ensuring motors run within safe electrical parameters, which extends their service life and reduces long-term maintenance costs. Its reliability is built on robust components and a design focused on precise fault detection, giving operators peace of mind. The compact and simple installation means it can be integrated into new setups or retrofitted into existing ones with minimal effort, delivering immediate protection and a rapid return on investment through avoided repair bills and sustained operational continuity.
