Schneider Electric Telemecanique LA3-D22 Time Delay Relay

The Schneider Electric Telemecanique LA3-D22 Time Delay Relay is an off-delay timer block in the TeSys D family used to provide controlled delayed switching for contactors in industrial motor control systems. It offers an adjustable off-delay timing range of 0.1 to 30 seconds, a 1 normally open plus 1 normally closed contact configuration, minimum switching voltage of 17 V, and minimum switching current of 5 mA, with a conventional free-air current rating of 10 A. The device is rated for insulation voltage Ui of 690 VAC and operating voltage Ue up to 690 VAC (25–400 Hz); it mounts via front clip-on for TeSys D contactors and uses screw clamp terminals for secure connections. Compatible with TeSys D devices (LC1D, CAD) and related control relays, the LA3-D22 supports roughly 5 million operating cycles and is a common replacement for Schneider Electric LADR2 Time Delay Auxiliary Contact Block in industrial motor control panels.
