product description 

A 3-pole manual motor starter is a device used to manually control the starting and stopping of a three-phase electric motor. It typically includes a manual operating handle or lever that allows the operator to manually engage or disengage the motor from the power source.

Here are some key features and functions of a 3-pole manual motor starter:

1. Three-phase Control: As the name suggests, it has three poles or contacts, each controlling one phase of the three-phase power supply. This allows for the balanced starting and stopping of the motor, which is essential for proper motor operation.

2. Manual Operation: Unlike automatic or remote-controlled starters, a 3-pole manual motor starter requires direct, physical interaction by an operator to engage or disengage the motor. This is done by moving the operating handle or lever to the appropriate position.

3. Circuit Protection: Manual motor starters often include overload protection features to prevent damage to the motor due to excessive current draw. This protection may be in the form of thermal overloads or magnetic trip units that sense the current flow and trip the starter if the current exceeds a preset limit.

4. Auxiliary Contacts: The starter may also include auxiliary contacts that can be used to signal the motor's status (e.g., running or stopped) or to control other equipment related to the motor's operation.

5. Flexible Mounting: Manual motor starters are typically designed for easy installation and mounting in a variety of electrical control panels or enclosures.

6. Durability and Safety: These starters are designed to withstand industrial environments and are typically constructed with safety features to prevent accidental activation or damage.

When operating a 3-pole manual motor starter, it is important to follow safety procedures, such as ensuring the power is off before making any adjustments or repairs, and using appropriate protective equipment, such as gloves and eye protection.

Remember, working with electrical equipment can be dangerous, so it's always advisable to consult with a qualified electrician or technician when installing, configuring, or maintaining a manual motor starter.
