Allen Bradley 1489-M1C400 Miniature Circuit Breaker, 40A, 1-Pole, Trip Curve C

The Allen Bradley 1489-M1C400 is a high-performance miniature circuit breaker designed for industrial and commercial applications requiring reliable overcurrent protection. This 1-pole breaker features a 40A current rating and a Trip Curve C, which provides medium magnetic trip sensitivity ideal for general-purpose loads like motors and lighting circuits. It is UL 489 listed, ensuring compliance with stringent safety standards for branch circuit protection. Key benefits include compact DIN rail mounting for space-efficient installation in control panels, high breaking capacity up to 10 kA at 240V AC, and robust construction for durability in harsh environments. Compared to similar products from competitors like Schneider or Siemens, the 1489-M series offers superior integration with Rockwell Automation systems, easier diagnostics, and a wider range of accessories. Drawbacks may include higher cost for non-Rockwell ecosystems and limited availability in some regions. Applications span automation, HVAC systems, and machinery protection. This listing appears to include a lot of 6 unused units (based on images: three boxes with Qty 2 each, plus six breakers shown), in excellent condition with original packaging for some. Serial numbers visible on boxes (e.g., 1207, PN-D16248).
