Product catalog summary
Product Overview: The document provides technical specifications for wire-wound resistors manufactured by KRAH-RWI Elektronische Bauelemente GmbH. These resistors are available in various styles and special versions upon request.
Specifications:
  • Resistance Range: The resistors have a specified resistance range, with tolerances provided for each model.
  • Power Rating: The nominal power rating is specified, along with dissipation values at different temperatures (40°C, 70°C, 200°C, 250°C, 300°C).
  • Limiting Voltage: Each model has a specified limiting voltage, ranging from 3000V to 6000V.
  • Dimensions: The dimensions are provided in millimeters, including the total length of the groove.
Materials: The bolt terminals are made of zinc-coated steel, and the flashover guard ferrules are anodized aluminum.
Product Variants: The document lists several models (e.g., UK 126 x 300, UK 126 x 400) with specific resistance values, power ratings, and dimensions.
Ordering Information: An example order designation is provided, illustrating how to specify the desired product model and quantity.
