IEEE 200-1975 or "Standard Reference Designations for Electrical and Electronics Parts and Equipments" is a standard that was used to define referencing naming systems for collections of electronic equipment. IEEE 200 was ratified in 1975. The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter.
IDEC was founded by Tsuneo Funaki in 1945 and it became a company organization in 1947. IDEC is known for its various electromechanical control products such as relays, timers, and switches. The company also manufactures automation products, such as micro-programmable logic controllers , power supplies, and touch-screen displays.

Electromechanical protective relays operate by either magnetic attraction, or magnetic induction. [9]: 14 Unlike switching type electromechanical relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics.
