Description
The Schneider Electric (Square D) LC1D253BD Contactor 3-Pole is an electrically operated switch for power circuit switching in HVAC systems. In normal working conditions, when the 24VDC coil is energized, an internal electromagnet drops, making the three normally open 3 NO main contacts. This action makes it possible for current to flow through the circuit and hence the connected equipment to function. Also, it has one normally open 1 NO and one normally closed 1 NC auxiliary contact for control circuit feedback or interlocking.
