The LADN049 is an auxiliary contact block from the TeSys Deca range, designed for front mounting on TeSys Deca contactors and reversing starters. It provides four normally-closed (4NC) instantaneous contacts, wired via Faston terminals, to signal contactor position or interlock control circuits. Rated operational current is 6 A at 120 V AC-15 (pilot-duty inductive loads), derating to 1.04 A at 690 V AC-15. For DC-13 solenoid loads, it handles 0.55 A at 125 V DC and 0.1 A at 600 V DC. The conventional free-air thermal current (Ith) is 10 A at 60 °C, protected by a 10 A GG fuse. Making capacity is 140 A AC and 250 A DC per IEC 60947-5-1, adequate for momentary inrush on pilot-duty solenoids.
Integration Notes
Mounts on the front of TeSys Deca contactors (e.g., LC1D series) without additional hardware. The IP20 finger-safe enclosure suits panel installation where incidental contact is possible. The block occupies 44 mm width and 42 mm depth on the contactor face. Minimum switching requirements of 5 mA at 17 V ensure reliable dry-circuit signalling to a PLC input without contact wetting.
