IP20 on the wired terminals and other faces, IP40 on the front panel outside the connection zone. Operating altitude 2000 m, shock 10/15 gn depending on pole position, vibration 2–4 gn over 5–300 Hz. 60 mm deep, 45 mm wide, 66 mm tall — fits a standard 1.8-inch-wide slot on the rail. Listed to EN/IEC 60947-6-2 and UL 60947-4-1 with phase barrier, CSA C22.2 No 60947-4-1 with phase barrier — the trio covers most North American and European panel specs. Fire resistance at 960°C for live parts, 650°C for others. Safe separation at 400 V SELV between control/auxiliary and main circuits. The part carries the TH protective treatment per IEC 60068 for humid environments. RoHS/REACH declarations are standard with the brand; request them with the order.","metaTitle":"Schneider Electric LUCB1XB TeSys Ultra Advanced Control Unit","metaDescription":"Schneider LUCB1XB TeSys Ultra advanced control unit for motor protection.
