Description
Schneider Electric LADR4 Time Delay Auxiliary Contact Block is an electrical component used in control circuits of various industrial applications. It is used to add a time delay element to the operation of a circuit. It has one Normally Open (NO) contact and one Normally Closed (NC) contact. These contacts can be used to control other devices in an electrical circuit.
Off Delay 10-180s means that after the trigger condition is met, there will be a delay of 10 to 180 seconds before the contacts actually change state. The wiring or connections are located at the front of the component for easy access. Screw Clamp Terminal is the type of terminals used for connecting wires. Screw clamp terminals are common in industrial applications and allow for a secure connection.
Schneider Electric LADR4 Time Delay Auxiliary Contact Block is used for applications that need a delayed response after a trigger event, such as turning off a motor after a certain period of time.
