0441 OHMITE Rheostat

Review OHMITE Rheostat 100 Watt Model Series Nib

The Ohmite 0441 rheostat is a versatile and reliable adjustable resistance device designed for various applications where precise voltage regulation or current limiting is required. This rheostat is manufactured by Ohmite, a leading name in the field of resistive components.

The Ohmite 0441 rheostat is a wirewound type, which means it uses a resistive wire wound on a drum or cylinder to provide adjustable resistance. This design offers several advantages, including high power handling capacity, stability, and durability. The resistance value of this rheostat can be adjusted continuously by rotating a dial or a knob, allowing fine-tuning of voltage or current to meet specific application requirements.

The Ohmite 0441 rheostat comes in various power ratings, ranging from 1 A to 150 A, and resistance values from 0.1 ohms to 200 ohms. The specific resistance value and power rating selected will depend on the particular application and the amount of power and current that needs to be regulated or limited.

The Ohmite 0441 rheostat features a robust construction with a porcelain base and a brass housing. The knob is made of bakelite or other insulating material, ensuring safe operation even when the rheostat is adjusted while in use. The resistance wire used in the rheostat is made of high-quality materials, such as carbon composition or metal film, to ensure long-lasting performance and stability.

The Ohmite 0441 rheostat also includes several safety features to protect against overheating and electrical faults. These include a temperature limiter, which automatically disconnects the rheostat when it reaches a certain temperature, and a current limiting fuse, which protects against overcurrent conditions.

Overall, the Ohmite 0441 rheostat is an excellent choice for applications where precise voltage or current regulation is necessary, such as in laboratory experiments, industrial processes, or power supply systems. Its rugged design, adjustable resistance, and safety features make it a reliable and versatile component for a wide range of applications.
