Latest Patents

Kleemeier’s listed patents focus on protective devices that detect electrical faults and help disconnect a conductor network.

- **Fault-current protection device with an overload protection device.** This invention combines a mains-independent residual-current tripping circuit with mains-powered overload protection. Both circuits use a common tripping relay to operate the switching mechanism.

- **Protective device, in particular a fault-current protective device.** This invention uses two detection systems to respond to fault currents at different frequencies. One system handles currents below a changeover frequency, while the other handles currents above it; the changeover frequency is preferably at least 1 kHz.
