Ohmite E300K4R0E Vitreous Enamel Power Resistor
OHMITE's 280 Series Corrib resistors are robust power resistors ideal for demanding applications involving high currents and low resistance values. Constructed with corrugated resistive wire and a protective vitreous enamel coating, these resistors offer exceptional durability and cooling efficiency. They are particularly well-suited for motor starting, dynamic braking, and other applications requiring frequent start-stop cycles. Custom units with higher wattage ratings are available upon request. The hollow-core design allows for secure mounting to chassis surfaces.
