Functional Features:
- Overvoltage Protection: Crowbar circuit design provides rapid short-circuit protection against overvoltage conditions in drive systems.
- High-Voltage Equipment Control: Controls circuit breakers, disconnect switches, and other high-voltage equipment in medium-voltage switchgear.
- High Precision: Uses high-precision electronic components to ensure control accuracy.
- High Reliability: Industrial-grade design with strong anti-interference capability and wide working temperature range.
- Easy Integration: Standard terminals provided for user-friendly connection.
Application Scenarios:
- Power generation plants
- Electrical substations
- Industrial factories
- Mining operations

- Railway systems
- Marine and shipboard applications
Material and Structure:
- High-quality printed circuit board with robust copper traces
- Industrial-grade electronic components
- Compact design for integration into control cabinets
Working Principle: The crowbar board monitors system voltage levels and rapidly triggers a short-circuit path (crowbar action) when dangerous overvoltage conditions are detected, thereby protecting sensitive downstream equipment from damage.
Important Note: This product has been discontinued by ABB. Replacement parts or alternative solutions are required for ongoing system maintenance. Factory warranty may no longer apply.
