L1D09P7 The LC1D09B7 is a specific model within the Schneider Electric TeSys D range of contactors. These are industry-standard components used for switching electrical power circuits, most commonly for controlling motors. Here is the full breakdown of what this part number represents and its technical capabilities. Part Number Breakdown The nomenclature tells you exactly what the device does: LC1D: TeSys D Range (3-pole contactor). 09: Rated for 9 Amperes (AC-3 operational current). B7: Indicates the control coil voltage is 24V AC at 50/60 Hz. Technical Specifications The LC1D09B7 is designed for reliability and high cycle rates. Power Circuit Poles: 3 NO (Normally Open) power contacts. Rated Operational Voltage (U e ​ ): Up to 690V AC. Motor Power: 2.2 kW at 220/230V AC. 4 kW at 380/400V AC (Standard industrial motor size). 5.5 kW at 660/690V AC. Utilisation Category: AC-1 (Resistive loads) and AC-3 (Motor starting/stopping). Control &amp; Auxiliary Coil Voltage: 24V AC. Auxiliary Contacts: Built-in 1 NO + 1 NC (Normally Open + Normally Closed) contacts for signaling or interlocking. Mounting: Can be clipped onto a 35mm DIN rail or screw-mounted to a plate. Key Features High Endurance: Mechanical durability of roughly 15 million cycles. Safety: Features a protective cover to prevent accidental manual operation and IP20 finger-safe terminals. Flexibility: Compatible with a wide range of add-ons, such as thermal overload relays (LRD series), auxiliary contact blocks (LADN), and pneumatic timers. Applications You will typically find this contactor in: Small motor starters (pumps, fans, conveyors). Heating and lighting control circuits. Industrial automation panels where a 24V AC control signal is used for safety or standardized logic. Would you like me to find a compatible thermal overload relay to pair with this contactor for motor protection?
