Telemecanique lh4 n225qn7 soft starter

The Telemecanique LH4 N225QN7 Soft Starter is an advanced electronic device made to start and stop a motor in a sequence. Telemecanique is globally recognized for its high reliability and efficiency of industrial motor control solutions. The LH4 N225QN7 supports its motors with better protection, decreases the mechanical stress during its movement, and thus strengthens the overall efficiency of the motor-driven systems. It supports soft start and soft stop functions. As a result, it is often utilized in operations that require stepwise acceleration or deceleration.

Key Features:

1. Soft Start & Soft Stop Functions: The LH4 N225QN7 facilitates a smooth start and soft stop of the motor, reducing inrush current and mechanical stress on the motor and the equipment that goes with it.

2. Wide Voltage Range: This product is suited for 380/415 V AC systems. The operating frequency ranges between 50/60 Hz, hence applicable for multiple industrial purposes.

3. Current and Overload Protection: It continuously handles current up to 25.3 A, which provides fundamental overload protection for the motor and system components.

4. High Power Rating: The device supports motors that are power-rated up to 7.5 kW (10 HP), making it applicable to a wide range of medium power motors.

5. Compact Design: The device is only 800 g in weight, and its structure makes it easy to install in control panels that have minimal space for an installation.

6. Compliance with International Standards: It is in compliance with IEC 947.4.2, thereby ensuring international compatibility with industrial standards.

7. Auxiliary Contacts: LH4 N225QN7 has auxiliary contacts, B300. This makes the integration with other components and control circuits possible with flexibility.

8. Energy Efficiency: By reducing the starting current and eliminating mechanical shocks, it saves energy and extends the life of the motor and all associated equipment.

9. Wide Operating Range: It accommodates a wide range of wire gauges (AWG 10 – 18) and offers easy wiring options for installation.

Applications:

1. Pumps: It avoids water hammer that may cause jerks in pump start-up, and sudden jerks or stoppages in compressors, valves, and pressure vessels, among others, in stopping the pumps slowly.

2. Conveyors: To avoid sudden jolts and stops in the conveyor system for smooth material flow and protection to the mechanical equipment.

3. HVAC Systems: Optimizes motor operation of fans, blowers, and compressors in HVACs, thus giving less wear to the system.

4. Sack Slitting and Packaging Machines: This is particularly suited for gradual acceleration and deceleration in machines handling packaging materials, such as sack slitters, without causing damage to the material.

5. Fans and Blowers: The starting of large fans or blowers results in reduced inrush current, ensuring a long motor life and minimal stress on electrical circuits.

6. Compressors: The compressors are started and stopped without jerky movements that might cause system failures or mechanical damage.

7. Mining and Construction Equipment: It is ideal for applications where heavy-duty motors are required, such as crushers, mills, and other machinery used in mining or construction.
