About this item
Siemens 3UA50 40-0J 0.63-1A 690v Overload Relay
New product out of manufacturer's box
Model: 3UA50 40-0J
. The overload relay helps prevent motor damage that can occur due to overheating caused by high electrical currents.
The basic function of an overload relay is to monitor the current flowing through the motor. If the current exceeds a certain limit for a specific period of time, the overload relay is triggered and shuts down the motor. This protects the motor from damage caused by overheating due to abnormal operating conditions.
Overload relay 0.63...1 A tripping class: 10A size 0 for 3TF30/31,3TF40/41,3TB40/41 AUX. contacts: 1 NO + 1 NC
The Siemens 3UA50 40-0J 0.63-1A overload relay is an electrical protection device that acts to protect electric motors against thermal overloads. It is designed to be installed in motor control circuits and consists of a bimetal, an output contact, and a safety fuse.
The bimetal is a bimetallic element, composed of two metal strips with different coefficients of thermal expansion. When the bimetal is heated, the two strips expand at different rates, causing the bimetal to bend. This bending opens the
relay's output contact, interrupting the motor control circuit.
The safety fuse is an additional protection device that is designed to protect the thermal relay from damage. If the bimetal fails to open the output contact, the safety
fuse will blow, interrupting the motor control circuit.
The Siemens 3UA50 40-0J 0.63-1A overload relay is a reliable and efficient device that can help protect your electric motors from damage.
Here are some of the key features of the Siemens 3UA50 40-0J 0.63-1A Thermal Relay:
Rated current: 0.63-1A
