STARTERS:
10-AMPS or 2-in-1:
A 10-amp or 2-in-1 motor starter is an electrical device used to start, stop, and protect electric motors with a maximum current rating of 10 amperes. It is commonly used for small motors in pumps, fans, compressors, or machine tools. These starters are typically designed for both single-phase and three-phase systems and are compatible with voltages ranging from 220V to 415V AC.
The starter usually includes key components such as a contactor and a thermal overload relay. The contactor switches the motor on and off, while the thermal overload relay provides protection against overcurrent and overheating, automatically disconnecting the motor when necessary. The system may also include manual controls like push buttons and auxiliary contacts for automation or signaling purposes.
10A starters are available in different types such as Direct-On-Line (DOL) starters, which are the most basic and economical, or soft starters that gradually ramp up motor speed to reduce mechanical stress.
They are often enclosed in protective IP-rated casings, making them suitable for both indoor and outdoor industrial environments.These starters are built according to international standards like IEC or NEMA to ensure safe and reliable operation.
Components of a 10A Starter:
Contactor
- Electromechanical switch for starting/stopping motor
- Coil operates on control voltage (usually 24V, 110V, 230V AC/DC)
- Rated for 10A in this case
Thermal Overload Relay
- Protects motor against overload
- Trip range adjustable around 7–10A depending on model
- Bimetallic strip trips the relay when excessive heat is sensed
Enclosure (optional)
- IP-rated for dust/water protection
- Wall-mounted boxes in industrial environments
Real-World Usage:
Domestic Applications:
- Water Pumps (1 to 2 HP): For overhead tank filling or garden irrigation
- Small Air Compressors: Used in home garages or workshops
- Motorized Gates or Doors
Agricultural Applications:
- Borewell Pumps
- Drip Irrigation Systems
- Agitator Motors for Mixers
Industrial Applications:
- Conveyor Belts: Light-duty loading or packaging lines
- CNC Machines & Lathes: For tool spindle control
- Exhaust Fans & Blowers
- Coolant Pumps
Commercial Usage:
- HVAC Systems: Small motors in air handling units
- Elevator Door Motors
- Automatic Sliding Gates
SPECIFICATION:
- Starter Types:
- 10A Starter (2 in 1 or suitable for 10 HP motor)
- Input Supply: 3-Phase, 440V, 50 Hz AC supply.
- Auto Mode: The motor turns on automatically based on the timer (set in seconds).
- Phase Failure Protection: If there is a fault in at least one phase, the starter will automatically trip.
- Voltage Protection: The starter will trip automatically if the input voltage drops below 350V or exceeds 460V.
- LCD Display: Displays voltage, current, and error messages clearly.
- LED Indicators: Show specific errors like High Voltage, Low Voltage, Phase Fault, and Overload.
- Motor Safety Function: Designed to protect motors from issues like bearing faults, float failure, or gearbox problems—if the load (amps) increases, the starter trips automatically.
- Portable Design: Compact, lightweight, and easy to carry.
- Self-Protection: Equipped with a fuse (0.1A or 100mA) for internal protection.
- Enclosure: Supplied with a durable PVC enclosure.
20 Amps or 4-in-1
The 20 Amps or 4-in-1 Starter is designed to control and protect motors up to 10 HP, operating on a 3-phase 440V, 50 Hz AC supply. With a current handling capacity of 20 amps, this starter is ideal for larger motor applications such as aerators, pumps, and industrial machines. It combines multiple functionalities in one compact unit, including Auto Mode (timer-based), Manual Mode (push-button), Overload Protection, and Phase/Voltage Protection, hence the “4-in-1” name.
Equipped with an LCD display, the starter provides real-time information on voltage, current, and fault conditions.
Additionally, LED indicators alert users to specific problems such as High Voltage, Low Voltage, Phase Failure, and Overload, ensuring fast diagnosis. If the incoming voltage drops below 350V or exceeds 460V, or if any phase is missing, the starter automatically trips to protect the motor.
