The ISOVAC (Integrated, Spatially Optimised Vacuum Circuit Breaker) is a fixed-type 12/24kV Vacuum Circuit Breaker designed to be mounted within LKE's IV2000 Air-Insulated M.V switchboards. The ISOVAC-M has the following features:

• Maximum breaking capacity of up to 31.5kA
• Short-circuit withstand current of up to 31,5kA / 4sec
• It is driven by a low energy single-coil permenant-magnet actuator system which includes a manual tripping and manual closing function
• It is capable of more than 50,000 mechanical operations and 20,000 electrical operations.
• Compact design which integrates an isolating-switch module (Optional), a vacuum interrupter module, a current and voltage sensor module(Optional), an earth-switch module (Optional) and an interlocked operating mechanism module into one single system.
• Final panel dimensions may be as compact as 475mm X 1800mm X 900mm (WXHXD) for 12kV systems and 520mm X 2000mm X 1100mm (WXHXD) for 24kV systems for a single IV2000 panel.
