Time relays

Time relays are electrical devices used to control delays between events in a circuit, delaying the activation or deactivation of a load after a set time. They consist of a timing mechanism and contacts that switch once the delay period has passed, enabling control of devices like motors, lights, and alarms. These relays are essential in automation and control systems, often used in industrial applications for motor protection, lighting control, heating systems, and sequential operations. They are manufactured according to standards like IEC 61812-1, EN 61812-1, and UL 1054, which ensure their safety and performance. Well-known manufacturers like Wilo, Siemens and Weidmüller, along with other leading manufacturers, offer their 3D CAD models on 3Dfindit, including time relays.
