Ensure Continuous Farming Operations with Minilec Pump Protection Relays
In India’s agriculture sector, where water pumps are essential for irrigation and productivity, sudden electrical failures can disrupt operations and damage expensive equipment. Minilec offers a comprehensive range of water pump protection relays specifically engineered for Indian farming conditions. These devices protect submersible and monoblock pumps by monitoring 3-phase supply and providing intelligent protection against electrical faults.
Whether you’re dealing with single phasing, reverse phasing, or unbalanced voltage, Minilec’s Auto Switch and Single Phasing Preventors act as the first line of defense ensuring your motor doesn’t run under unsafe conditions.
Why You Need Pump Protection Relays for Farming Applications
Farmers in India frequently face challenges such as unstable power supply, phase loss and voltage imbalance. Running a pump during these conditions can lead to motor burnout, dry running or operational failure resulting in costly repairs and crop loss.
Minilec’s pump protection relays are designed to automatically detect these anomalies and safely switch off the motor to prevent damage. With features like auto reset, on-delay timers and manual override, these devices provide both automation and flexibility.
Key Features of Minilec Pump Protection Devices
- 3-Phase Supply Monitoring: Continuously checks phase health and voltage balance
- Pre-Wired Terminals: Makes installation inside starter panels quick and easy
- Auto-Manual Switch: Flexibility to operate pumps manually or automatically
- Adjustable On-Time Delay: Avoids nuisance tripping and protects during power restoration
- Built-in Timer for Star-Delta Starters: Perfect for semi-automatic control panels
- Dual-Mode Protection: Works seamlessly in both Auto and Manual modes
These protection relays are crafted for rugged Indian usage from remote farmlands to large-scale irrigation systems
Built-in Electrical Protections
Each Minilec model includes a combination of the following protections:
- Single Phasing Protection: Detects loss of any one phase and shuts down the pump
- Reverse Phasing Protection: Prevents damage due to reverse rotation
- Unbalanced Voltage Detection: Monitors voltage differences across phases
- Dry Run Protection: Stops pump when no water is detected (select models)
- On Delay Timer: Prevents frequent restarts during intermittent power supply
