Schneider Electric LC1D09B7 TeSys D Contactor – 9A, 440V AC-3, 24V AC Coil
The Schneider Electric LC1D09B7 is a TeSys D / TeSys Deca 3-pole contactor with 3NO power contacts, rated 9A AC-3 at up to 440V AC. It features a 24V AC 50/60Hz control coil, 1NO + 1NC auxiliary contacts, and compact DIN-rail mounting, making it suitable for motor control, industrial automation, HVAC, pumps, fans, and machine-control applications.
Description
The Schneider Electric LC1D09B7 TeSys D contactor is a compact and reliable 3-phase motor contactor designed for switching and controlling electrical motors and other industrial loads. With a 9A AC-3 rating at ≤440V AC, it is well suited to small and medium motor-control applications.
The LC1D09B7 is equipped with a 24V AC control coil operating at 50/60Hz, making it compatible with control circuits using a 24V AC supply. The contactor provides 3 normally open (3NO) main contacts and includes 1NO + 1NC auxiliary contacts for control logic, interlocking, signalling, and status feedback.
As part of the Schneider Electric TeSys D / TeSys Deca range, the LC1D09B7 supports flexible panel installation through 35mm DIN-rail or screw mounting. Its compact 45mm width makes it suitable for space-conscious electrical control panels.
The LC1D09B7 Schneider contactor is particularly suitable for industrial automation panels, motor starters, HVAC equipment, pumps, fans, conveyors, compressors, and general machine-control systems where a 24V AC control voltage is required.
