Schrack RT174012 12V DC PCB Power Relay – 10A, SPDT Changeover Contact

Description

Product Overview
The Schrack RT174012 is a general-purpose power relay from the Schrack RT1 sensitive relay series. It uses a 12V DC control coil to operate an electromechanical contact, allowing a low-voltage control signal to switch a separate electrical circuit.
Its single changeover contact provides normally open and normally closed switching paths. The compact PCB-mount design makes it suitable for compatible electronic control boards, timer circuits, and automation equipment. The RT174012 is identified by TE Connectivity part number 3-1393239-8.
