Ohmite 280 Corrib® Series Fixed Resistors


The 280 series of heavy-duty power resistors from Ohmite are constructed with corrugated resistive wire. The wire is fused to the ceramic core by a protective vitreous coating, ensuring improved durability. The corrugated wire and ribbed construction enables rapid cooling. With a hollow core unit, these power resistors can be fastened to chassis surfaces with brackets and through bolts.

Features & Benefits:


Tinned lug terminals with holes

Adjustable lug supplied with adjustable 300 W models

±10% tolerance

Overload: 10 times rated wattage for 5 seconds

750 W or above models feature silicone coating

Product Applications:


These power resistors are suitable for applications requiring low resistance at high current capacity. For example, the 300 W model has resistances as low as 0.1 Ω. These power resistors are ideal for dynamic braking and motor starting applications.
