What is the main function of a contactor? A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. How does off delay timer work? With ON-delay operation, the Timer receives input and then an output signal is an output by switching the Timer contacts after a set time delay. This name is used because there is a delay between when the input signal is received (i.e., turns ON) and when the output signal is output. What is a phase failure relay? The Phase Failure Relay is a phase-voltage-balance monitoring device designed for use with magnetic controls to automatically prevent three-phase motors or other equipment from operating or attempting to start up under open phase or single-phase conditions, thereby eliminating burnouts and consequent down-time ... Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. ... When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized. An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may be used to prevent undesired states in a finite-state machine and may consist of any electrical, electronic, or mechanical devices or systems. more contents on contactors    • Direct online starter|Control ciruit|...   Understand phase failure/ monitor    • Explaining phase monitor|phase failur...   Subscribe to my channel    / @electreca1
