The CHM2DIU is a two-pole modular DIN-Rail fuse holder designed for UL supplemental and IEC 10x38 fuses with IP20 finger-safe construction. It is rated for 600 Vac/30 A (UL) and 690 V/32 A (IEC) with a short-circuit current rating (SCCR) of 200 kA RMS symmetrical, and features open fuse indication capability. The holder mounts on standard 35 mm DIN-Rail and accommodates wire sizes from #18 to #4 AWG (0.8 mm² to 21.1 mm²) in solid, stranded, or fine stranded copper conductors rated at 75°C or 90°C. It is UL Recognized (File E14853, Guide IZLT2), CSA certified (File 47235, Class 6225-30), and complies with IEC 60269-2 and CCC standards, with UL 94V0 self-extinguishing flammability rating. The CHM2DIU is ideal for industrial control panels, distribution systems, and applications requiring modular, ganged fuse protection with optional remote PLC fuse indication monitoring.
