The 2NC configuration is the one you reach for when you need a positive-break feedback on a safety circuit or a seal-in that drops out cleanly. The rated operational current changes with the duty: 6 A at 120 V AC-15 (typical solenoid or contactor coil load), dropping to 1.04 A at 690 V AC-15. On DC control circuits, it handles 0.55 A at 125 V DC-13 and 0.1 A at 600 V DC-13 — that's enough for a DC coil holding circuit but not for a motor brake directly. Minimum switching is 5 mA at 17 V, so it reliably wets low-energy PLC inputs without contact oxidation over time. Making capacity is 140 A AC and 250 A DC per IEC 60947-5-1, with short-time withstand of 100 A for 1 s, 120 A for 500 ms, and 140 A for 100 ms. The 10 A GG fuse protection limit says the upstream fuse should be sized to that — no bigger, or the contact block becomes the weak link in a fault. Mounts on the front of any TeSys Deca contactor or reversing contactor — the snap-in terminals accept 1 to 4 mm² flexible or rigid wire (with or without ferrule) on the main terminal, and 1 to 2.5 mm² on the second terminal. The block is IP20 finger-safe, so it's fine inside a standard control panel with the door closed. Dimensions are 42 mm deep, 44 mm wide, 48 mm tall — about the footprint of a DIN-rail terminal block. Altitude rating goes to 3000 m without derating. The TH protective treatment per IEC 60068 means it's tested for humid tropical environments — no extra conformal coating needed for most indoor industrial settings. Certified to EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, and GB/T 14048.5. Also listed to EN 50012 and the glow-wire tests of IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ, which covers heat exposure in HVAC equipment.","metaTitle":"TeSys Deca LADN02A Auxiliary Contact Block, 2NC, 10A","metaDescription":"LADN02A auxiliary contact block, TeSys Deca series, 2NC, front mount, snap-in terminals.
