Overview
The Westinghouse OT2B with OT2D is an oil tite contact block assembly used in industrial motor control and electrical switching applications. This legacy component combines the OT2B (normally open contact configuration) with the OT2D (normally closed contact configuration), providing dual switching capability for control circuits. Oil tite design ensures reliable performance in harsh industrial environments.
Key Features
- Oil tite sealed contact block design for environmental protection
- Dual contact configuration: OT2B (normally open) and OT2D (normally closed)
- Reliable electrical switching for motor control applications
- Legacy Westinghouse component compatible with older control systems
- Compact form factor suitable for panel-mount installations
