OT1W

The Westinghouse Ot1w Cutler Hammer Oil Tite Contact Block 20312 is a versatile and reliable electrical component designed for use in various industrial and commercial applications. This contact block is part of the Oil Tite series, which is known for its ability to prevent oil and coolant contamination in electrical circuits.

The Ot1w contact block is a single-pole, double-throw (SPDT) design, meaning it can be used to switch between two circuits. It is constructed with high-quality brass material, ensuring durability and resistance to corrosion. The contacts are silver-plated, providing excellent conductivity and reducing the risk of arcing and sparking.

One of the standout features of the Ot1w contact block is its Oil Tite seal, which is designed to prevent contaminants from entering the electrical connections. This seal creates a tight, watertight seal around the contacts, keeping out oil, coolant, and other contaminants that could cause shorts or other electrical issues.

The contact block also features a captive screw design, which makes installation and maintenance easy and efficient. The screws are held in place by the block itself, eliminating the need for separate screws or hardware. This design also helps to prevent the screws from loosening over time, ensuring a secure electrical connection.

The Ot1w contact block is rated for a maximum voltage of 600 volts and a current of 20 amps, making it suitable for use in a wide range of industrial and commercial applications. It is also UL listed, ensuring that it meets the highest standards for safety and quality.

Overall, the Westinghouse Ot1w Cutler Hammer Oil Tite Contact Block 20312 is a high-performance electrical component that offers superior protection against contaminants, easy installation, and reliable operation. It is an essential component for any industrial or commercial electrical system that requires a secure and contamination-free connection.
