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.

Tinned lug terminals with holes

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.

Ribbed construction aids in rapid cooling
Designed for equipment requiring low resistance loads at low ohmic values and high current capacity
Especially constructed for motor starting, dynamic braking, etc

Corrib resistors are ideal for applications involving high currents at very low resistance values as low as 0.1Ω for the 300 Watt unit. These large, heavy duty resistors are designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. Special order units are available to accommodate up to 1500 watts. Corribs are manufactured with corrugated resistive wire. To accelerate cooling, the wire is securely fused to the ceramic core by the protective vitreous enamel coating to improve durability. Corrib resistors are hollow-core units which can be securely fastened to chassis surfaces with thru bolts and brackets.
