Siemens 3RU21164AB0 Overload Relay

Product Description:

• An Overload Relay is a protective device used to safeguard electrical motors and circuits from damage due to excessive current (overload conditions).
• It does not respond to short circuits but protects against sustained overcurrent that can overheat the motor.
• They are often integrated into motor control panels and are part of a motor starter or motor control circuit.
• They are commonly use in industrial and commercial settings where motors power a wide range of machinery and equipment.
• The overload relay monitors the current flowing through the motor.
• It does this by using a current sensor, such as a thermal element (often a bimetallic strip) or electronic current measurement circuit.
• Overload relays protect motors from overheating, which can lead to motor burnout or damage to winding insulation.
