Corrib® resistors are ideal for applications involving high currents at very low resistance values—as low as 0.1Ω for the 300 Watt units. 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. FEATURES • 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. SPECIFICATIONS Material Coating: Lead free vitreous enamel except for extreme low resistance 35 watt models, and very large models (1000 watts and up), which are supplied in Silicone Ceramic. Core: Tubular Ceramic. Terminals: Tinned lug with hole. Adjustable Lug: Supplied with adjustable 300 watt models. Part No. 1974-A or 1974-B. Electrical Tolerance: ±10% (K) Power rating: Based on 25°C free air rating. Derating: Linearly from 100% @ +25°C to 0% @ +400°C. Overload: 10 times rated wattage for 5 seconds. Temperature coefficient: ±400 ppm/°C. Dielectric withstanding voltage: 1000 VAC measured from terminal to mounting bracket.
