Vacuum Interrupters has introduced the RVI-PV-74A, a direct replacement vacuum interrupter designed for use in General Electric Limitamp contactors.
The RVI-PV-74A is engineered as a fit-and-function replacement for GE PV-74A vacuum interrupters and is compatible with GE Limitamp CR193D, CR193VB, and CR193WB vacuum contactors. The unit meets original equipment ratings and is built to deliver high-voltage insulation, strong cumulative and breaking capacity, internal torsion control, and a robust vacuum seal using fine alumina ceramic.
Key technical specifications
- Rated current: 400 A RMS
- Maximum voltage: 7.2 kV RMS
- Impulse withstand: 60 kV peak
- Short-circuit breaking current: 7 kA RMS
The replacement interrupter requires no modification for installation in existing GE Limitamp contactors, helping minimize downtime during maintenance or retrofit projects. Vacuum Interrupters also offers compatible assembly components and mounting hardware to streamline installation.
The RVI-PV-74A expands the company’s portfolio of replacement vacuum interrupters and components for medium-voltage circuit breakers and contactors, supporting continued operation of legacy and in-service equipment across industrial and utility applications.
