The Gelco ELCW+ (4–20 Amp) is a single-phase electronic motor starter and protection panel designed for operating and safeguarding submersible, openwell, and monoblock water pumps (typically 0.75 HP to 3 HP capacity). Key Features & Functions Adjustable Current Rating (4–20 Amp): Features an adjustable electronic overload current range from 4 Amp to 20 Amp, allowing custom setup according to the motor's specific rating. Complete Electrical Protection: Electronic Overload Protection: Cuts off power automatically if the motor draws excess current due to mechanical binding, worn-out bearings, or over-usage. Dry-Run Protection: Detects under-load conditions when there is no water flow and trips the motor automatically to prevent overheating and dry-run pump damage. High & Low Voltage Trip: Automatically disconnects power during severe voltage drops or spikes to protect motor windings. Digital Display Unit: Equipped with a built-in digital display that monitors real-time line voltage, operating current (Amperes), and fault/trip indicators. Auto-Start & Delay Timers: Features an automatic restart functionality after power cut recovery or dry-run wait periods with configurable OFF-time delay timers. Technical Specifications Operating Voltage: 230V AC, 50 Hz (Single Phase) Load Current Range: 4 Amp to 20 Amp (Settable) Motor Capacity: Suitable for ~0.75 HP up to 3 HP pumps Over-Voltage Cutoff: > 280V Low-Voltage Cutoff: < 150V–160V Enclosure: Heavy-duty powder-coated sheet metal panel Applications: Domestic water lifting pumps, agricultural single-phase submersibles, commercial building water supply systems.
