Rated at 10 A conventional free air thermal current (Ith) at 60 °C, it handles 6 A at 120 V AC-15 and 0.55 A at 125 V DC-13 — the AC-15 figure governs solenoid and contactor coil loads, while the DC-13 rating applies to electromagnetic loads with a high inrush. Insulation voltage is 690 V per IEC 60947-5-1, with a making capacity of 140 A AC and 250 A DC per the same standard — enough to handle momentary inrush from a contactor coil without welding the contacts. The 2 NC configuration is common for safety circuits or feedback loops where the closed state must be verified. IP20 protection means it is suitable for installation inside a control cabinet, not in washdown or outdoor locations. The TH protective treatment per IEC 60068 confirms it can handle humid, tropical environments typical of untreated enclosures. Mechanical durability of 30 million cycles means this block outlasts most contactor bodies it pairs with — the wear limit is usually the main contactor's electrical life, not this auxiliary. ## Integration notes Mounts on the front of a TeSys D or TeSys Deca contactor or reversing starter. Faston terminals accept wire; the 26 mm width matches the contactor footprint, so no extra DIN rail space is consumed. The minimum switching current of 5 mA and minimum voltage of 17 V mean it can reliably switch PLC-level signals, not just power loads — useful for low-energy feedback circuits.","metaTitle":"LADN029 TeSys Deca Auxiliary Contact Block, 2 NC, Faston Ter","metaDescription":"LADN029 TeSys Deca auxiliary contact block, 2 NC, Faston terminals.
